Commandbutton with id("myButtonId2") works fine. I mean it updates "myOutputPanel"
but commandbutton(myButtonId) which is inside datatable doesn't update outputPanel. I found the suggestions and tried with the following,
update=":myForm:myOutputPanel"
update="#myForm"
update=":myOutputPanel"
But none of them worked...
Here is the snippet...
<h:form id="myForm" prependId="false">
<p:panel id="myPanel">
<p:dataTable id="myDatatable">
<p:column style="width:4%">
<p:commandButton id="myButtonId" actionListener="#{bean.showPanel}" update="myOutputPanel"/>
</p:column>
</p:dataTable>
<p:commandButton id="myButtonId2" update="myOutputPanel"/>
</p:panel>
<p:outputPanel id="myOutputPanel" rendered="#{bean.show}">
//some stuff
</p:outputPanel>
Try to put your <p:outputPanel /> inside a <p:panel />
and add a "widgetVar" attribute
For example : <p:panel widgetVar="var" [..]>
and just update the panel directly with update="#widgetVar(var)"

I have two selectBooleanCheckbox in differet tabs that are linked to the same variable in the backend bean, like this:
.xhtml:
<p:tabView id="tabsView" widgetVar="tabPanelWidget" dynamic="true" cache="true">
....
<p:tab id="tab1">
<p:outputPanel id="panel1">
<p:fieldset toggleable="false">
<p:panelGrid id="panelGrid1">
<p:row>
<p:column>
<p:outputLabel for="toggle1"/>
<p:selectBooleanCheckbox id="toggle1" value="#{backingBean.toogleBool}">
<p:ajax update="#(.toggle2)"/>
</p:selectBooleanCheckbox>
<p:column>
</p:row>
</p:panelGrid>
</p:fieldset>
</p:outputPanel>
</p:tab>
....
<p:tab id="tab2">
<p:outputPanel id="panel2">
<p:fieldset toggleable="false">
<p:panelGrid id="panelGrid2">
<p:row>
<p:column>
<p:outputLabel for="toggle2"/>
<p:selectBooleanCheckbox id="toggle2" value="#{backingBean.toogleBool}">
<p:ajax update="#(.toggle1)"/>
</p:selectBooleanCheckbox>
<p:column>
</p:row>
</p:panelGrid>
</p:fieldset>
</p:outputPanel>
</p:tab>
</p:tabView>
backingBean.java :
....
#Getter #Setter private boolean toggleMailAnhangExtrahieren = true;
....
Obviously this isn't my whole code as that would be too much to post here but I hope I included everything relevant. As you can see I try to use ajax to update the other selectBooleanCheckbox when one of them is clicked. As they are bound to the same variable, I would expect both selectBooleanCheckboxes to have the same status (both checked or both unchecked), but the other checkbox does not update. What am I doing wrong?
You need to fix the update part in the p:ajax tags:
#(.<class>) is a class-selector (Primefaces is using the jQuery Selector API, see https://api.jquery.com/category/selectors/), but you want to reference an id. So just use the id itself in the p:ajax tag, e.g.
<p:ajax update="toggle2"/>
Try using the tab id like this:
<p:ajax update="#form:tabsView:toggle2"/>
I am using buttons in a p:datatable and they are triggering a p:blockUI (PF 6.0)
When located in the footer of my datatable, the button does trigger the blockUI. When moved into a column, it does not trigger it
BlockUI
<p:blockUI block="blockPanel"
trigger="myForm:myTable:myButton myForm:myTable:myButton2">
Loading..<br />
<p:graphicImage name="images/loading_blue.svg" />
</p:blockUI>
Datatable
<p:panel id="blockPanel">
<h:form id="myForm">
<h:panelGrid columns="1" cellpadding="5">
<p:dataTable id="myTable" value="#{modelBean.myList}" var="entry">
<!-- Some data -->
<p:column headerText="Name">
<h:outputText value="#{entry.name}" />
</p:column>
<!-- Does not work -->
<p:column style="text-align: center">
<p:commandButton id="myButton" actionListener="#{bean.method()}" />
</p:column>
<!-- Works -->
<f:facet name="footer">
<p:commandButton id="myButton2" actionListener="#{bean.method()}" />
</f:facet>
</p:dataTable>
</h:panelGrid>
</h:form>
</p:panel>
Why ?
The following workaround did not work for me:
<p:commandLink ... onclick="bui.show()" oncomplete="bui.hide()">
...
<p:blockUI widgetVar="bui" />
As a workaround, I used pe:blockUI:
http://www.primefaces.org/showcase-ext/sections/blockui/blockPage.jsf
What I mean : You don't have any value in your datatable. Put it one, you can create a backingBean return one value and add property value=#{myBean.value}. Also you have data on you datatable ! Test it
I would create a check input information about specified in:
http://www.primefaces.org/showcase/ui/message/messages.xhtml
I create a dataTable with a lot required field (inputText with attribute required="true") and a p:message into datatable section.
Problem is when I click on button to save data: I don't see alert message in my page but starting execution of associated bean.
Why?
My code in .xhtml is this:
<h:form>
<p:messages id="messages" showDetail="true" autoUpdate="true" closable="true" />
<p:dataTable var="myAtt"
value="#{myBean.attributes}"
rowIndexVar="myAttIndex">
<h:inputHidden value="#{myAtt.value}" rendered="#{myAtt.description == 'XXX'}" />
<p:column rendered="#{myAtt.description == 'XXX'}">
<h:outputText value="*" rendered="#{myAtt.required}" />
</p:column>
<p:column rendered="#{ myAtt.description == 'YYY'">
<p:fragment rendered="#{myAtt.description == 'ZZZ'">
<p:fragment rendered="#{myAtt.value == 'value1'}">
<p:inputText size="#{myAtt.maxLength}"
value="#{myAtt.value}"
rendered="#{myAtt.const == 't1'}"
required="true"
id="idText">
<p:ajax process="#this" event="change" update="#form"/>
</p:inputText>
<p:message for="idText"/>
</p:fragment>
</p:fragment>
</p:column>
</p:dataTable>
<br />
<p:commandButton value="Create" action="#{myBean.commit()}" process="#this" update=":MYPAGE"/>
Thanks.
You forgot to indicate an id for the h:form : <h:form id="myForm">
And in the update of the p:commandButton you have to indicate the id of the form : update=":MYPAGE :myForm"
EDIT
According to the PrimeFaces users guide 3.5, the attribute action will be called when the user clicks on the button.
I have a datatable, and at the last column I will have an edit action, it will trigger the dialog box. However, I found the value in the dialog box is not updated. Can anybody to help on this?
My code as below. In fact the bean.currentItem.name and bean.currentItem.age should base on my selection from the table. I check the bean.currentItem is not null and is refer to my selection from preEdit method, but the value never show up in p:dialog.
<p:dataTable ....>
<p:column...
<p:column...
<p:column>
<f:facet name="header">
<h:outputLabel value="Update" />
</f:facet>
<p:remoteCommand name="preEdit" action="#{bean.preEdit}"
process="#this" update="#this #form:dlg">
<f:setPropertyActionListener target="#{bean.currentItem}"
value="#{thisItem}" />
</p:remoteCommand>
<p:commandLink styleClass="no-decor"
oncomplete="preEdit();PF('dlg').show();" value="Edit"/>
</p:column>
</p:dataTable>
<p:dialog header="#{lbl.tt_cat_upd}" widgetVar="dlg" id="dlg"
resizable="false" >
<h:outputLabel value="#{bean.currentItem.name}" />
<h:outputLabel value="#{bean.currentItem.age}" />
</p:dialog>
How about removing your p:remoteCommand and let your p:commandLink do all the work for you?
Assuming you have a h:form surrounding both your dataTable and your dialog
<p:commandLink action="#{bean.preEdit}" process="#this" update="dlg" styleClass="no-decor" oncomplete="PF('dlg').show()" value="Edit">
<f:setPropertyActionListener target="#{bean.currentItem}"
value="#{thisItem}" />
</p:commandLink>
If your dataTable is not in the same form with your dialog, you might replace update="dlg" by update=":formIdContainingDialog:dlg"
I have this piece of code:
<h:body>
<h:form id="form1">
<p:menuButton value="#{msgs.settingsMenuButton}">
<p:menuitem value="#{msgs.accountsMenuItem}" url="#" update=":dlgEdit" oncomplete="_dlgEdit.show()"/>
</p:menuButton>
<p:commandButton value="Accounts" icon="ui-icon-gear"
update=":dlgEdit"
oncomplete="_dlgEdit.show()"/>
</h:form>
<p:dialog id="dlgEdit" widgetVar="_dlgEdit" modal="true" closable="true" header="Accounts">
<h:form id="frmEdit" >
<p:panelGrid id="pnlEdit" columns="2">
<p:outputLabel id="lblName" for="eName" value="Name"/>
<p:inputText id="eName" value="#{tasksBean.selectedLocation}"/>
</p:panelGrid>
</h:form>
</p:dialog>
</h:body>
The dialog is not displayed when the menuItem is selected but it works when the commandButton is pressed.
The behaviors for both are the same...
Can you support me please?
Thanks,
Andrei
Try:
oncomplete="PF('_dlgEdit').show();"
