I'm just starting with PrimeFaces 3.3.1 coming off RichFaces 3 and 4.
I have a datatable with the structure:
<f:facet name="header">
<h:outputText value="Employees" />
</f:facet>
<p:column sortBy="#{emp.lastName}">
<f:facet name="header">
<h:outputText value="Last Name" />
</f:facet>
<h:outputText value="#{emp.lastName}" />
</p:column>
<p:column>
<f:facet name="header">
<h:outputText value="First Name" />
</f:facet>
<h:outputText value="#{emp.firstName}" />
</p:column>
...
<p:column>
<p:commandButton icon="ui-icon ui-icon-trash"
value="Remove"
process="@this"
update="employee-remove-dialog"
oncomplete="employeeRemoveDialog.show();">
<f:setPropertyActionListener target="#{employeeManager.currentEmployee}" value="#{emp}" />
</p:commandButton>
</p:column>
</p:dataTable>
<p:dialog header="Remove Employee"
modal="true"
appendToBody="true"
widgetVar="employeeRemoveDialog"
id="employee-remove-dialog">
<h:outputText value="Remove employee #{employeeManager.currentEmployee.fullName}?" />
<f:facet name="footer">
<p:commandButton icon="ui-icon ui-icon-check"
value="OK"
action="#{employeeManager.deleteEmployee}"
process="@this"
update="employee-list"
oncomplete="employeeRemoveDialog.hide();" />
<p:commandButton icon="ui-icon ui-icon-close"
value="Cancel"
onclick="employeeRemoveDialog.hide();"
ajax="false"
immediate="true" />
</f:facet>
</p:dialog>
</h:form>
However PrimeFaces throws an exception:
09:36:08,961 SEVERE [javax.enterprise.resource.webcontainer.jsf.application] (http-localhost-127.0.0.1-8080-1) Error Rendering View[/employeeList.xhtml]: javax.faces.FacesException: Cannot find component with identifier "employee-remove-dialog" referenced from "j_idt30:employee-list:0:j_idt41".

The ID cannot be found. Hmm.... I basically copied the structure from RichFaces. There the row button to delete or edit the row doesn't need the :employee-form:... prefixing. I wonder why.
When giving the form an ID and prefixing the PF component references with the ':' syntax the code runs as expected:
<h:form id="employee-form">
<p:dataTable ...>
...
<p:column>
<h:panelGrid ...>
<p:commandButton ...
update=":employee-form:employee-remove-dialog"
...>
...
</p:commandButton>
</h:panelGrid>
</p:column>
</p:dataTable>
<p:dialog ...
id="employee-remove-dialog">
</p:dialog>
</h:form>
Q:
Why does a p:datatable need to prefix the root JSF IDs? Maybe it's my code, but the example posted seems minimal to me. In any case, using this will result in possibly long IDs all over the application.
What am I doing wrong?
PS: I'm on JBoss AS 7.1.1.Final, Mojarra 2.1.7, PF 3.3.1
