Martin Marinschek commented on MYFACES-1197:
--------------------------------------------
Not quite - you wouldn't need to provide a var, cause the
parentComponentClientId would always store the client-id of its immediate
parent (optionally, one might supply a for-attribute for the then renamed
component).
So it would look like this:
<h:form id="someForm">
<t:storeParentComponentClientId/>
<h:inputText id="name" required="true"/>
<h:panelGroup rendered="#{myfacesContext.ifMessage['name']}">
<!-- some markup to support the error message -->
<h:message for="name"/>
</h:panelGroup>
</h:form>
and the internal implementation of ifMessage would look up the component by
finding first the parent component (for which it has the client-id) and then
finding the component with the id name on the parent.
