Why are comopnents of another form validated with JSF 2.3? - primefaces

I just upgraded to JSF 2.3 & Wildfly 14 (from 2.0 and 13) and primefaces 6.2.5.
I noticed a strange behavior when i use a command button. I have 2 forms and when a push the button of the first form, the input of the second form is validated and the error (in this case required errors) are displayed in a p:message :
<h:form id="form1" prependId="false">
<p:commandButton id="save" value="Save" actionListener="#{myBean.save()}" update="#form">
<f:actionListener binding="#{myBean.reloadResults()}" />
</p:commandButton>
<p:messages id="msgs" severity="error,warn" escape="false">
<p:autoUpdate />
</p:messages>
...
</h:form>
<p:dialog >
<h:form id="form2" >
<p:messages severity="error,warn" escape="false">
<p:autoUpdate />
</p:messages>
<div>
<p:calendar id="myDate" value="#{myBean.myDate}" required="true" />
</div>
...
</h:form>
</p:dialog>
I was expecting only the content of the first form to be processed and validated. This was the case with wildfly 13 and jsf 2.0.
Any idea?

You have not specified attribute process in your command button. Default value of this is #all which will validate all Forms.
Please use process="#form" to avoid validation and process of other form.
Updated code is as below:
<p:commandButton id="save" value="Save" actionListener="#{myBean.save()}" update="#form" process="#form">
<f:actionListener binding="#{myBean.reloadResults()}" />
</p:commandButton>

I have to apologize for not posting the entire code but it would have been to big. I found out what the problem was. It's related to this bug:
https://github.com/primefaces/primefaces/issues/4122
I have a panelgrid of 4 columns but with 10 elements in it.
The whole ajax communication was then broken. Fix is coming in PF 6.3

PrimeFaces confirmDialog won't show after changing language

I have a form with a datatable inside it . In one of the columns is a button to delete that row. That button has a primefaces confirm dialog attached to it.
<h:form id="form" style="text-align: -webkit-center">
<p:dataTable id="preferenceConfigs" var="preferenceConfig"
value="#{preferenceManagementBackingBean.preferenceConfigs}">
<p:column style="width:6rem; text-align: center">
<p:commandButton update=":form"
title="#{msgs['common.delete.userpreference.button']}"
icon="fa fa-trash"
action="#{preferenceManagementBackingBean.invalidatePreferenceConfig(preferenceConfig)}">
<p:confirm header="Confirmation" message="#{msgs['common.dialog.preference.config.warning']}"
icon="fa fa-exclamation-circle" escape="false"/>
</p:commandButton>
</p:dataTable>
<p:confirmDialog global="true" showEffect="fade" hideEffect="fade" style="text-align-last: center">
<p:commandButton value="#{msgs['common.dialog.confirm.yes']}" type="button"
styleClass="ui-confirmdialog-yes" icon="fa fa-check"/>
<p:commandButton value="#{msgs['common.dialog.confirm.no']}" type="button"
styleClass="ui-confirmdialog-no" icon="fa fa-times"/>
</p:confirmDialog>
</h:form>
Everything works fine until I change the language on the page through a commandLink. They are located in a masterLayout file above this one:
<h:form id="generalSettingsForm">
<ul id="language">
<li><h:commandLink
action="#{languageSessionBean.changeLanguage('en')}" value="EN"
class="blgm_lSwitch" id="EN"/></li>
<li><h:commandLink
action="#{languageSessionBean.changeLanguage('nl')}" value="NL"
class="blgm_lSwitch" id="NL"/></li>
<li><h:commandLink
action="#{languageSessionBean.changeLanguage('fr')}" value="FR"
class="blgm_lSwitch" id="FR"/></li>
</ul>
</h:form>
public void changeLanguage(String language) {
locale = new Locale(language);
findCurrentFacesContext().getViewRoot().setLocale(locale);
}
This refreshes the page and displays the correct language. However pressing the remove button now automatically performs the action without any sign of the confirmation dialog. Only if I open another dialog (that is present in the JSF page) and return, will the confirmation shows its face again...
The dev console gives me the following error:
VM1391 components.js.xhtml:13 Uncaught TypeError: Cannot read property 'style' of undefined
at c.show (VM1391 components.js.xhtml:13)
at c.showMessage (VM1391 components.js.xhtml:13)
at Object.confirm (VM1391 components.js.xhtml:1)
at Object.confirm (VM1390 core.js.xhtml:1)
at HTMLButtonElement.onclick (preferenceManagement.xhtml:58)
Any insight?
Seems that confirmDialog doesn't play well with ajax updating.
Normally a language change means that all the parts of the page must be updated, so there is no benefit in using partial updating.
The easy way to solve it is to set ajax to false on your commandLinks:
<h:commandLink action="#{languageSessionBean.changeLanguage('fr')}"
value="FR" class="blgm_lSwitch" id="FR" ajax="false" />
After some more googling, it seems to be an issue with primefaces 6.2 with the following behaviour:
confirmDialog does not show, an error is logged on console (TypeError:
this.jqEl is undefined)
This was fixed in 6.2.2. I cannot test this myself since all minor releases are for paying users only. As a workaround, I'll try a custom dialog. You can probably also use primefaces 7.0
official github with reproducer
Could you try to put the p:confirmDialog out of the form? Something like this:
<p:confirmDialog global="true" showEffect="fade" hideEffect="fade" style="text-align-last: center">
<p:commandButton value="#{msgs['common.dialog.confirm.yes']}" type="button"
styleClass="ui-confirmdialog-yes" icon="fa fa-check"/>
<p:commandButton value="#{msgs['common.dialog.confirm.no']}" type="button"
styleClass="ui-confirmdialog-no" icon="fa fa-times"/>
</p:confirmDialog>
<h:form id="form" style="text-align: -webkit-center">
<p:dataTable id="preferenceConfigs" var="preferenceConfig"
value="#{preferenceManagementBackingBean.preferenceConfigs}">
<p:column style="width:6rem; text-align: center">
<p:commandButton update=":form" icon="fa fa-trash"
title="#{msgs['common.delete.userpreference.button']}"
action="#{preferenceManagementBackingBean.invalidatePreferenceConfig(preferenceConfig)}">
<p:confirm header="Confirmation" message="#{msgs['common.dialog.preference.config.warning']}"
icon="fa fa-exclamation-circle" escape="false"/>
</p:commandButton>
</p:dataTable>
</h:form>
Using the version primefaces 6.2 the same thing happened to me, then searching hard I found this solution that worked perfectly, I hope it helps someone, in the web xml add:
<context-param>
<param-name>primefaces.MOVE_SCRIPTS_TO_BOTTOM</param-name>
<param-value>true</param-value>
</context-param>

Why JSF form maintain the validation styles even if has values on it?

I have a form (frmAddPax) to add some users data. This data could be submited manual or vía a barcode reader. When the button "Escanear" is pressed this one calls a dialog with another form (frmScan).
This form read some data from a barcode reader and this data is processed in the managed bean. The data creates an object that is used in the original form (frmAddPax).
The problem is all the form has the styling as there wasn't any data on it, all the mandatory fields have the required="true" attribute.
If I press the "Escanear" button again and scan the same data it shows the form just fine.
I think this could be because before the data is ready updated in the form the validation process happend, but as I have seen in some questions the action and actionListener events happend before the update process so I have no clue.
This is the code of the form:
<h:form id="frmAddPax"
rendered="#{MB.renderStatus.isRenderFormAddPax()}">
<p:panelGrid styleClass="no-border">
<p:row>
<p:column>
<h:outputText
value="#{label['manageVipLoungeEntrance.addPassenger.firstName']} />
</p:column>
<p:column>
<p:inputText required="true"
value="#{manageVipLoungeEntranceExtMB.passenger.firstName}"
style="text-transform: uppercase;" converter="upperCaseConverter">
<f:ajax event="blur" update="#this" render="#this" />
</p:inputText>
</p:column>
...
...
<!-- BOTON ESCANEAR AGREGAR PASAJERO -->
<p:column>
<p:commandButton inmediate="true"
value="#{label['manageVipLoungeEntrance.addPassenger.button.scan']}"
onclick="showLocalDate()" update=":frmScan"
actionListener="#{manageVipLoungeEntranceExtMB.clear}"
oncomplete="{wgvScan.show()}" />
</p:column>
<!-- BOTON ESCANEAR AGREGAR PASAJERO -->
</p:row>
</p:panelGrid>
This is the code for the call that made the "Escanear" button:
<p:commandButton inmediate="true"
value="#{label['manageVipLoungeEntrance.addPassenger.button.scan']}"
onclick="showLocalDate()" update=":frmScan"
actionListener="#{manageVipLoungeEntranceExtMB.clear}"
oncomplete="{wgvScan.show()}" />
And this is the code for the widtget that process the barcode read and updates the original form with the data processed.
<p:dialog widgetVar="wgvScan" modal="true" showEffect="fade"
closeOnEscape="true" resizable="false">
<h:form id="frmScan">
<p:graphicImage value="../resources/images/barCode.png"
rendered="#{manageVipLoungeEntranceExtMB.showTablePassenger!=true}" />
<p:inputText id="itbarcode"
rendered="#{manageVipLoungeEntranceExtMB.showTablePassenger!=true}"
value="#{manageVipLoungeEntranceExtMB.barCode}" onfocus="true"
autocomplete="off" styleClass="insertData"
style="background:#ffffff; position:absolute;left:-7000;" />
<p:commandButton id="cmdReadBarcode" style="display:none"
onclick="showLocalDate()"
actionListener="#{manageVipLoungeEntranceExtMB.readBarCode}"
update=":frmAddPax :growl">
</p:commandButton>
<p:defaultCommand target="cmdReadBarcode" />
...
</h:form>
[EDIT]
#alibttb answer get me to the solution.
I added a remoteCommand before the button that calls the dialog to listen the scanner.
<p:remoteCommand name="refreshForm" process=":frmAddPax" update=":frmAddPax" />
<p:commandButton
value="#{label['manageVipLoungeEntrance.addPassenger.button.scan']}"
onclick="showLocalDate()" process="#this" update=":frmScan"
actionListener="#{manageVipLoungeEntranceExtMB.clear}"
oncomplete="{wgvScan.show()}" />
</p:column>
And in the dialog with the form that process the barcode I added a onHide attribute calling the remoteCommand.
I change the enclouse of the dialog-form to form-dialog as was sugested.
<h:form id="frmScan">
<p:dialog widgetVar="wgvScan" modal="true" showEffect="fade"
closeOnEscape="true" resizable="false" onHide="refreshForm()">
What happens when you click the Escanear button is that you are processing the whole form, thus submitting all the fields with empty values, this will cause validation errors, your button is immediate so what happens is the following:
actionListener is immediate so it's called first and the managed bean is filled with data from a barcode scanner.
the form data is being validated and it's not valid so the inValid flag is set on all the inputs.
the response is created on the server containing an update for the form, showing the new values from the managed bean and the inValid state of the inputs from the validation process.
notice that the submitted data (empty values) is not applied to the model as it's not valid.
to fix this, just use partial processing feature on your button, and remove the immediate="true", it's just a bad design.
just replace immediate="true" with process="#this" in the Escanear button.
If you're not familiar with partial processing feature of JSF and primefaces you should give it a look.
if you really need to submit the form for validation after the scan is complete then you need to use a p:remoteCommand that submits the form after the actionListener is complete:
<p:remoteCommand name="validateForm" process="#form"/>
<p:commandButton value="#{label['manageVipLoungeEntrance.addPassenger.button.scan']}"
onclick="showLocalDate()" update=":frmScan" process="#this"
actionListener="#{manageVipLoungeEntranceExtMB.clear}"
oncomplete="{wgvScan.show()}" />
and in the other form frmScan do:
<h:form id="frmScan">
<p:dialog widgetVar="wgvScan" modal="true" showEffect="fade"
closeOnEscape="true" resizable="false" onHide="validateForm()">
....
....complete your code
the name of the p:remoteCommand becomes a javascript function that can be called back once the scan dialog is hidden.
Note bring up the dev console in your browser and watch the two requests one for updating the form and closing the dialog and the other one caused by p:remoteCommand to validate the form.
Note 1 (not related to your question) that I used the frmScan to enclose p:dialog this is the right way to do it, the form should surround the dialog not the other way around.

p:sticky not working in p:dialog

I can't seem to make p:sticky work inside a p:dialog :
my dialog xhtml :
<p:dialog modal="true" height="490" width="700" resizable="false" >
<h:form id="form">
<p:toolbar id="tb">
<p:toolbarGroup align="right">
<p:commandButton value="save" />
</p:toolbarGroup>
</p:toolbar>
<p:sticky target="form:tb" />
</h:form>
</p:dialog>
It works fine from a simple page. any thoughts?
You are not doing anything wrong, it is just not supported. And due to a 'bad' issue report, it is closed as invalid http://code.google.com/p/primefaces/issues/detail?id=6341
Looking at the javascript source code of the sticky component, it checks scrolling of the window and not any other part inside it. So there is a big chance it will also fail in e.g. a p:layout.

Primefaces Dialog box - show it conditionally. javascript code not working

I want to show a dialog box on the click of a primefaces commandbutton. Before the dialog box , I need to check a condtional.
I am using Spring web-flow 2.3.0.
So I am doing it like this ,
And the Dialog Box is
I am not able to show this dialog box based on this condition.
Please help me ,any pointers?
SWF 2.3.0 Primefaces 2.2.1 JSF 2 Spring Security 3 Spring 3.1.0M1I EhCache Apache Tomcat 6.0 STS 2.5.1
So I have changed my code as per below
<p:commandLink id="addRequest" immediate="true" value="addreq"
oncomplete="dlg3.show()" update="dialogPanel">
<f:setPropertyActionListener
value="#{searchHandler.selectedAccIns}"
target="#{reqSearchHandler.checkAccStatus}" />
</p:commandLink>
And the dialog box is
<p:outputPanel id="dialogPanel"
rendered="#{not reqSearchHandler.accStatusFlag}">
<p:dialog header="Effect Dialog" widgetVar="dlg3"
showEffect="bounce" hideEffect="explode" height="200">
<h:outputText
value="Account is #{searchHandler.selectedAccIns.accStatusDesc}" />
<h:outputText value="Do you want to continue?" />
<div align="left">
<p:commandButton value="Yes" action="accept" />
<p:spacer width="960" height="5" />
<p:commandButton value="No" action="cancel" />
</div>
</p:dialog>
</p:outputPanel>
But when I am clicking on the command link , I am getting 3 dialog boxes. Can you please tell me why it is so?
Somebody else just posted the same problem! :)
You should use the oncomplete attribute instead of onclick of the commandButton. The click javascript event occurs before the page posts back, likely causing your dialog not to appear because of the page reloading.
oncomplete="dlg3.show()" will display the dialog AFTER the postback.

why isn't this jsf/ajax code submitting the values?

I'm embedding here a simplified version of a code that is not working for me.
What happens here is that there are 2 forms.
The first form contains an ajaxified <h:commandLink> (Using <f:ajax>)
The second form contains a form with values.
When the <h:commandLink> is pressed, the values in the second form are supposed to be submitted.
What happens in practice is that values are retrieved (the getter function is run) but are not submitted (the setter function never runs).
The <f:ajax> runs because I can see the listener method running and the second form does get rerendered after clicking the <h:commandLink> but, again, the setter functions are never run.
<body>
<h:form prependId="false">
<h:panelGroup >
<h:commandLink >
<f:ajax event="click"
execute=":form_with_values_to_update" render=":form_with_values_to_update"
listener="#{mrBean.clickListenerAction}" />
Do something
</h:commandLink>
</h:panelGroup>
</h:form>
<h:panelGroup>
<h:form id="form_with_values_to_update">
<fieldset>
<ui:repeat value="#{mrBean.aMemberOfBean.aListInAMemberOfBean}" var="listItem">
<h:panelGroup>
<h:outputText value="#{listItem.label}" />
<h:inputText id="contact_details_input"
value="#{listItem.value}" />
</h:panelGroup>
</ui:repeat>
</fieldset>
</h:form>
</h:panelGroup>
</body>
P.S - Using MyFaces JSF 2.1
The commandlink/button has to go in the same form as where the data of interest is in.
If that's not an option due to some design or business restrictions, then you need a second commandlink/button. First move the original commandlink/button back in the right form, give it an id and hide it using CSS display: none;.
Then put the second commandlink/button in the other form which does something like
<h:commandLink onclick="document.getElementById('form_with_values_to_update:linkid').click(); return false;">
Do something
</h:commandLink>
