Hi I have a xhtml (html1), which has a save button. The click of this renders method1 of Managedbean1. This method1, inturn called method2 of ManagedBean2 and on success, brings up html1. Is there a way to have a progressbar in html1 and see though both the managedbean actions and display till html2 comes up. So far, all the examples i see have one ui and one managedbean.
#mareckmareck - Thanks for your reply. This is what I am trying to do. - Please see the code excerpts.
regbudget.xhtml
<div id="actionButtonBarNew">
<p:panel styleClass="buttonPanelNew" >
<p:commandButton id="saveBudget" value="Save Budget" type="button" onclick="pbAjax.start();startButton1.disable();" widgetVar="startButton1" />
<p:progressBar widgetVar="pbAjax" value="#{regbudgetMgmtMB.handleBudgetEvent}" ajax="true" labelTemplate="{value}%">
<p:ajax event="complete" listener="#{progressBean.onComplete}"
update="growl" oncomplete="startButton1.enable()" render="#form" update="messages,fcotcol" /> />
</p:progressBar>
</p:panel>
</div>
=======================
RegbudgetBean (//regbudgetMgmtMB)
------------------------------
public void handleBudgetEvent(AjaxBehaviorEvent evt){
// more codee--- code here --
try {
HourAllocationManagedBean hbean = getCurrentInstanceOfHourAlloc();
hbean.calculateHourAlloc();
}
===============================
HourAllocationManagedBean
public void calculateHourAlloc() {
if(logger.isDebugEnabled()){
logger.debug("HourAllocationManagedBean: calculateHourAlloc");
}
//more code here---
try{
FacesContext.getCurrentInstance().getExternalContext().redirect("/pages/budget/hourAlloc.xhtml");
}
====================================================
As you can see, i am in regbudget.xhtml, call handleBudgetEvent in RegbudgetBean , which inturn calls calculateHourAlloc in HourAllocationManagedBean and displays hourAlloc.xhtml. My requirement is to have the progressbar in regbudget.xhtml to show progress till the houralloc.xhtml is displayed. Could you please let me know if you have any suggestions. Thanks.

I show a Primefaces Dialog using the dialog framework, in this way:
RequestContext.getCurrentInstance().openDialog("myDialog", options, params);
In the page myDialog.xhtml I have a message and two buttons: YES or NO.
I would like to close the Pf dialog with the event "onclick", is there a way the to do this?
I cannot statically define the dialog using p:dialog and than close it using PF('widgetVarName').hide();
Generally, you may want something like this:
<p:commandButton action="#{someBean.closeDialog('yes')}" process="#form" update="#form"
icon="#{icons.yes}" value="#{bundle.yes}" />
<p:commandButton action="#{someBean.closeDialog('no')}" process="#form" update="#form"
icon="#{icons.no}" value="#{bundle.no}" />
public void closeDialog(String choice)
{
RequestContext requestContext = RequestContext.getCurrentInstance();
Object someData = executeChoice(choice);
requestContext.closeDialog(someData);
}
Otherwise, if you really need to close the dialog on onclick (sounds a little strange...) you may use:
<p:remoteCommand name="closeDialog" action="#{someBean.closeDialog}" process="#this" />
<p:commandButton type="button" onclick="closeDialog()" icon="#{icons.close}"
value="#{bundle.close}" />
public void closeDialog()
{
RequestContext requestContext = RequestContext.getCurrentInstance();
requestContext.closeDialog(null);
}
Finally, if you need a pure javascript solution, you may want:
<p:commandButton type="button"
onclick="PrimeFaces.closeDialog({pfdlgcid:'#{param.pfdlgcid}'})"
icon="#{icons.close}" value="#{bundle.close}" />
I have some problem to pass a entire bean in a dialog.
I would like to open a dialog with Dialog Framework in Primefaces, and pass the method and attributes content in bean.
I tried to make this code, but it don't work.How should I do?
<p:commandButton value="open dialog" ajax="true"
actionListener="#{processController.openSelectFieldDialog}"
update="tableResult , :notificationForm:info-messages">
<f:attribute name="controller" value="#{processController}" />
</p:commandButton>
This is the code inside openSelectFieldDialog method:
public void openSelectFieldDialog(){
RequestContext.getCurrentInstance().openDialog("genericSelectFieldDialog");
}
And this is the code inside the dialog controller:
public void onload() {
Object somethingBean= FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("controller");
}
I understand that i pass parameters on openDialog method, but i don't find any example on primefaces site. Can you help me?
Thanks
I want to get the value of the input Textarea and show it in the same page by clicking on the command button "compiler "
however i don't get any result ! and the contnet is only shown when I update with the browser updater
Sh How do I upate the page and the managed beans to show the content of a primefaces textarea in the same page
this is the code:
<p:layoutUnit position="west" size="520" header="Code à executer" resizable="true" >
<h:form id="moncode">
<p:inputTextarea id="mycode" value="#{fichier.code}" rows="17" cols="50" />
<p:commandButton value="compiler" id="btn3" action="guest.xhtml" styleClass="myButtonClass" />
</h:form>
</p:layoutUnit>
<p:layoutUnit position="east" size="550" header="Resultat d'execution" resizable="true" >
<h:outputText value="#{fichier.code}" />
</p:layoutUnit>
<p:layoutUnit position="south" >
my application is about compiling a given code: I write a code and then I executed with the button "compiler" so a file will be created however the file is always created with "null" and I think because the var "code" is not yet set in the managed bean that why I want to update the page so the managed bean ill be set here is compile:
`
private String code;
private String error;
public String getCode() {
return code;
}
public String getError() {
return error;
}
public void setCode(String code) {
this.code = code;
}
public void compile() throws IOException {
File file = new File("C:\\Users\\Rad1\\test.c");
PrintWriter ecrivain;
ecrivain = new PrintWriter(new BufferedWriter (new FileWriter(file)));
ecrivain.println(code);
ecrivain.close();
`
There are two ways to achieve what you want: either by using a synchronous submit of a form with a subsequesnt postback, or by sending an AJAX request to partially update necessary parts of the page.
Synchronous submit
<p:inputTextarea id="mycode" value="#{fichier.code}" rows="17" cols="50" />
<p:commandButton value="compiler" id="btn3" action="#{fichier.action}" styleClass="myButtonClass" ajax="false" />
<h:outputText id="upd" value="#{fichier.code}" />
with action method
public String action() {
//do business job
return null;
}
This way a fields will be refreshed by making a postback. Don't forget that the bean Fichier must be view scoped. Note the ajax="false" attribute of <p:commandButton>.
AJAX call
<p:inputTextarea id="mycode" value="#{fichier.code}" rows="17" cols="50" />
<p:commandButton value="compiler" id="btn3" action="#{fichier.action}" styleClass="myButtonClass" update="upd" />
<h:outputText id="upd" value="#{fichier.code}" />
with the same action method
public String action() {
//do business job
return null;
}
This way only the contents of <h:outputText> will be updated after AJAX call is finished. Don't forget that the bean Fichier should also be view scoped. Note that id attribute of <h:outputText> must be specified.
Actually, you don't call the action itself. Your action forwards to a certain page. There is no race condition or syncronization problems in a JSF action betwwen setting the properties and the action itself. I recommend you to read JSF life cycles tutorial by BalusC Aplly request values phase run before the action.
Try to call action on command Button.
<p:commandButton value="compiler" id="btn3" action="#{fichier.compile}" update="outputCode" styleClass="myButtonClass" />
Add an id attribute to your output panel and specify it in the action button.
<p:layoutUnit id="outputCode" position="east" size="550" header="Resultat d'execution" resizable="true" >
<h:outputText value="#{fichier.code}" />
</p:layoutUnit>
P.S. It is also good to read this BalusC answer for better understanding of actions, Ajax/non Ajax request etc.
I'm working on a PrimFaces mobile employee directory app and have hit a road block. Its a simple app which consists of two screens (employee filter/list + employee detail).
I was able to load a datalist without issues. Clicking on the commandlink properly loads the employee detail. I then was able to implement a custom employee filter which was somewhat painful, but I got that working. The filter works by repopulating the employee datalist's model with the filtered results.
The issue is, after I use the filter to repopulate/filter the datalist, clicking on an employee (commandlink) does not pass the correct employee ID back to the model. Instead, the employee ID that was there before the filter was performed is passed. It's like the JSF model is not matching the DOM.
I'm using:
TomEE (MyFaces 2.1.7)
PrimeFaces Mobile 0.9.3
PrimeFaces 3.3
Both of my backing models are #ViewScoped
<pm:view id="peopleDirView" onload="">
<pm:header title="People Directory" fixed="true">
</pm:header>
<pm:content>
<h:form id="form">
<div data-role="fieldcontain">
<fieldset data-role="controlgroup">
<p:inputText id="searchCriteria" value="#{peopleDirectoryBean.criteria}" type="search"
onkeyup="delay(function() {filterResults();}, 500);" />
</fieldset>
</div>
<p:dataList id="peopleDataList" value="#{peopleDirectoryBean.people}" var="person" rowIndexVar="rowIndex">
<p:column>
<p:commandLink action="#{peopleDirectoryDetailBean.loadPersonDetail(person.employeeId)}" update=":personDetailView">
<img src="/phonedir/people/image/#{person.employeeId}?width=75&height=100" width="90" height="100"
onerror="missingImage(this);" id="per-search-picture" />
<h1>#{person.nameLast}, #{person.nameFirst}</h1>
<p>#{person.deptName}</p>
<p>#{person.jobTitle}</p>
</p:commandLink>
</p:column>
</p:dataList>
<p:remoteCommand name="filterResults" update="peopleDataList" action="#{peopleDirectoryBean.peopleSearch}" />
</h:form>
</pm:content>
<pm:footer fixed="true">
<pm:navBar>
<p:button value="People" icon="home" href="#peopleDirView?reverse=true" styleClass="ui-btn-active" />
<p:button value="Locations" icon="info" href="#locationsView?reverse=true" />
<p:button value="Conference" icon="search" href="#conferenceRoomsView?reverse=true" />
</pm:navBar>
</pm:footer>
<script>
var delay = (function() {
var timer = 0;
return function(callback, ms) {
clearTimeout(timer);
timer = setTimeout(callback, ms);
};
})();
function missingImage(image) {
image.onerror = "";
image.src = "missing-person.jpg";
return true;
}
</script>
</pm:view>
Okay, looks like the mistake was on my part.
In my backing bean, I was using javax.inject.Named (#Named) because I was trying to make use of my container's ability to do CDI. Once I changed it to javax.faces.bean.ManagedBean (#ManagedBean ) the problem went away. The TomEE docs state that it supports #Named so I'm not sure what the deal is.
I'm trying the following:
labelconfig.xhtml:
<h:form id="ok">
<h:commandButton value="click">
<f:ajax event="click" listener="#{canvasController.oeps}" />
</h:commandButton>
</h:form>
And I'm trying to get it here:
CanvasController.java
#ManagedBean(name = "canvasController")
#SessionScoped
public class CanvasController
public void oeps(AjaxBehaviorEvent event) {
JOptionPane.showMessageDialog(null, "SUCCES3");
}
}
But when I click the button, I get:
serverError: class java.awt.HeadlessException
How is this caused and how can I solve it?
You are trying to call Swing from server application without any desktop GUI. Instead of JOptionPane use logger or FacesContext.addMessage to get feedback. If for some reason you do want to control Swing app through JSF make sure DISPLAY etc are set but then I suggest rephrasing your question.
