I am not able to open Dialog from my Bean. I have also tried actionListener instead of action
This is how my JSF looks like:
<ui:composition template="../templates/site.xhtml"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:p="http://primefaces.org/ui"
xmlns:sec="http://www.springframework.org/security/tags">
<!-- remove me just for encoding check ä -->
<ui:define name="content">
<h:form id="form">
<h:panelGrid columns="1" cellpadding="5">
<p:commandButton value="Button" type="button" id="myButton"
action="#{testBean.showDialog}" />
</h:panelGrid>
</h:form>
<p:dialog id="testDialog" widgetVar="testDialog2"
header="My Test Dialog" modal="true" appendToBody="true">
<h:form>
<h:outputText value="Output" />
</h:form>
</p:dialog>
</ui:define>
And this is my Bean
#Component
#Scope("view")
public class TestBean {
public void showDialog(){
RequestContext.getCurrentInstance().execute("testDialog2.show()");
}
}
Your showDialog() method is not called at all. Remove type="button" as you want to use AJAX enable submit, not push button.

On a single xhtml, I have two pages (p:page). Each page has a form and in each form, there is a growl defined. When I am on the first page, the growl is displayed upon clicking the button. However, when I am on the second page, the growl is not displayed. Below is the reproducible sample code.
The reason, why I did not use the update="#form", is that there is another form in an overlay panel and via #(.errorHandlingPanel) selector, I should be able to easily trigger the growl without knowing which page currently I'm on.

Thanks, ilhami visne
Somehow it seems the show method is not invoked after page navigation. The only workaround i found out is manually showing the message in ajax component oncomplete attribute using following method:
<p:growl id="growl" widgetVar="growlWidgetVar"/>
<p:commandButton outcome="pm:otherPage" update=":growl" oncomplete="showGrowl('growlWidgetVar');"/>
/*
* show current growl message again - PF-mobile bug on page navigation not showing it
*
* #param widgetVar PF widgetVar
*/
function showGrowl(widgetVar)
{
PF(widgetVar).show(PF(widgetVar).cfg.msgs);
}
The navigation often takes even place if a growl shall be shown. For this case call it in the pageshow handler instead:
$(document).on('pageshow', '#myPage', function(){
showGrowl('growlWidgetVar');
});
I have a p:dataTable and the selected value is throwing null pointer when Im tring to get it,this situation is after put the datatable inside a modal p:dialog, but if remove the modal atribute works fine.
PD:the modal p:dialog was behid the overlay like this question
Primefaces - AjaxStatus - Dialog is behind the overlay
the answer is not working for me, because Im using primefaces 5.1, so I have to use appendTo="#(body)"
I don´t know if that is important for my problem.
Resume: the null pointer exist if the p:dialog is modal.
Here is my code

You append your <p:dialog> to the body of the html page(see appendTo attribute), as a result it is not included in any <h:form>.
This could be a problem for your <p:dataTable>
Could you place your <h:form id="panotation"> inside of your <p:dialog> and not outside ?
I am using PF5, Jboss7, Mojarra 2.2 with Jdk1.7.
I have a dynamic tree with context menu. When I click on the menuitem, the page appears in the content panel. However, after that, looks like i lose all the listeners on the page including the tree. Cannot expand, second menuitem does not respond, basically, primefaces removes all the listeners on the page or, perhaps removes the form component, not sure.

I generated a Primefaces based CRUD website starting from JPA Entities with netbeans and after adjusting the Update dialog to fit my needs I am experiencing several problems. The domain Model is quite easy: I have an entity Invitation which contains several Guests.
#Entity
public class Invitation implements Serializable {
...
#OneToMany(cascade = CascadeType.ALL, orphanRemoval = true, mappedBy = "invitationId")
private List<Guest> guestList;
public List<Guest> getGuestList() {
return guestList;
}
...
}
I have an overview page (list.xhtml) where all the invitations are listed and the user can pick one to edit it.

Note that layout.xhtml doesn't contain any form (no nested forms).

And the Controller
#SessionScoped
#Named
public class InvitationController implements Serializable {
private Invitation selected; //with getter and setter
}
Now, I think my problem should be in the combination of p:dialog and h:form.
The original generated version of edit.xhtml had the form InvitationEditForm nested within the dialog and not the contrary as I posted above. The problem with that was after clicking editButton the dialog was loaded, but the dataTable was always filled with guests of the first Invitation I selected in my session (more strangely, suppose the first invitation in the session had just a guest A: after selecting an Invitation with 2 guests B and C I got A and B displayed). As the controller was returning the right guestList(), I supposed there was a problem with update and inverting form and display solved this problem..
Unfortunately this didn't solve all the problems, as now the actionListener for addGuestButton and deleteGuestButton doesn't get invoked anymore..
I am really confused: can you please help me to fix my code? Thanks in advance!
I have a DataTable (Primefaces 3.5, JSF 2.0) which is populated from a database. In the first column of this table, checkboxes are displayed (multiple row selection).
After selecting row(s), when a button (<p:commandButton>) is pressed, the selected rows are expected to be deleted from the database.
Before deleting row(s), a confirm message regarding the deletion of the selected row(s) is displayed in <p:confirmDialog> with two buttons Yes and No something like the following.
Test.xhtml:
<?xml version='1.0' encoding='UTF-8' ?>

The managed bean:
#ManagedBean
#ViewScoped
public final class TestManagedBean implements Serializable
{
#EJB(mappedName="ejb/JNDI")
private TestService testService;
private List<Test> list;
private List<Test>selectedValues;
public TestManagedBean(){}
#PostConstruct
public void init()
{
list=testService.getList();
}
public List<Test> getList() {
return list;
}
public List<Test> getSelectedValues() {
return selectedValues;
}
public void setSelectedValues(List<Test> selectedValues) {
this.selectedValues = selectedValues;
}
public void deleteMultipleActionListener(ActionEvent actionEvent)
{
//Just show a warning message, when the delete button is pressed.
for(Test test:selectedValues)
{
System.out.println(test.getId()+" : "+test.getDescription());
}//Displays the list.
}
public void deleteMultiple(ActionEvent actionEvent)
{
System.out.println("multiple");
for(Test test:selectedValues)
{
System.out.println(test.getId()+" : "+test.getDescription());
}//The list is not null and empty.
}
}
When the button (indicated by an arrow in XHTML) is pressed, the deleteMultipleActionListener() method in the managed bean is invoked where it simply displays the list which is populated by the selected rows and the confirm dialog as shown in XHTML appears afterwards. (This is just to show a warning message before deletion. The loop in this method is just for the demonstration).
When the Yes button on the confirm dialog is pressed, the deleteMultiple() method is invoked which is responsible for actual deletion of rows (actionListioner in <p:commandButton> inside <p:confirmDialog>) and the deletion of rows should be performed but here the list of the selected rows retrieved here is empty (not null).
The resulting list inside the deleteMultiple() method is empty because of <f:view> on the template page. The template page is shown below.

When I remove this template from the above Test.xhtml page and use this <f:view> tag on the Test.xhtml page itself, everything works fine and the list of the selected rows inside the deleteMultiple() method is obtained correctly.
So, what is going wrong? Why does the list become empty when the Yes button is pressed, if the template page is enclosed by <f:view>? Is it wrong? How to accomplish this? (<f:view> is used for the localization of the application as it can be imagined).
Your problem is solved when you replace the process="#this datatable" in your confirmDeleteMultiple by process="#this", which makes the button component only be processed. In fact you don't need Ajax to process your datatable when you send the deletion confirmation, because values for deletion are already stored in the bean since previous step (that's the main benefit of the view scope).
Making your datatable to be processed in your Ajax request invokes again the setSelectedValues setter, so the original value is getting overriden by the new (empty) selection.
