Modal dialogs BUG - jsf

Question

I have this code, currently working:
<?xml version="1.0" encoding="UTF-8"?>
<ui:composition 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"
template="/templates/default.xhtml">
<ui:define name="content">
<h:form id="form">
<p:dataTable id="clienti" var="c" value="#{clientiController.clienti}" rowKey="#{c.id}">
<p:column headerText="Ragione sociale">
<h:outputText value="#{c.ragioneSociale}" />
</p:column>
<p:column headerText="Codice fiscale">
<h:outputText value="#{c.codiceFiscale}" />
</p:column>
<p:column style="width:4%">
<p:commandButton
update=":formDialog:clienteEditDialog"
oncomplete="clienteEditDialog.show()"
value="Modifica"
title="Modifica">
<f:setPropertyActionListener value="#{c}" target="#{clientiController.clienteSelezionato}" />
</p:commandButton>
</p:column>
</p:dataTable>
<p:commandButton
value="Aggiorna"
actionListener="#{clientiController.aggiorna}"
update=":form:clienti"
icon="ui-icon-arrowrefresh-1-n" />
<p:commandButton
value="Nuovo Cliente"
actionListener="#{clientiController.nuovo}"
update=":formDialog:clienteEditDialog"
oncomplete="clienteEditDialog.show()" />
</h:form>
<h:form id="formDialog">
<p:dialog
header="Modifica Cliente"
widgetVar="clienteEditDialog"
id="clienteEditDialog"
showEffect="fade"
hideEffect="explode"
closable="true">
<h:panelGrid id="clienteEditDialogTable" columns="2" cellpadding="10" style="margin:0 auto;">
<p:outputLabel for="fieldNome" value="Ragione Sociale:" />
<p:inputText id="fieldNome" value="#{clientiController.clienteSelezionato.ragioneSociale}" />
<p:outputLabel for="fieldCodice" value="Codice:" />
<p:inputText id="fieldCodice" value="#{clientiController.clienteSelezionato.codiceFiscale}" required="true" requiredMessage="Codice fiscale obbligatorio" />
</h:panelGrid>
<p:commandButton
value="Conferma modifiche"
actionListener="#{clientiController.modifica}"
update=":form:clienti"
oncomplete="clienteEditDialog.hide()"
rendered="#{clientiController.clienteSelezionato.id!=null}" />
<p:commandButton
value="Conferma nuovo cliente"
actionListener="#{clientiController.crea}"
update=":form:clienti"
oncomplete="clienteEditDialog.hide()"
rendered="#{clientiController.clienteSelezionato.id==null}" />
</p:dialog>
</h:form>
</ui:define>
</ui:composition>
Now I'd really like my dialog to be modal, so I add modal=true to my .
The result is my dialog appears "under" the overlay.
After a bit searching, I found that appendToBody=true would solve my problem, so I try it and my dialog appears the right way.
But... WTF??! Buttons inside the dialog stop working!!
BUG? Or is there any solution?

Answer 1

Move <h:form id="formDialog"> inside the dialog
Because when you use appendToBody=true the content of the dialog being appended to the BODY of your page... And in you case its being taken outside the h:form and as you know commandButtons must reside within a h:form in order to work....
Like this
<p:dialog appendToBody="true".....
<h:form id="formDialog">
.....
When working with dialogs allays remember to place your h:forms inside the dialog...
