When having a rich:dataTable whose value is a List of objects (saying List<User>), the suggestion completion (aka CA) is done on the var attribute and works fine:

<rich:dataTable value="#

{myBean.userList}

" var="_user">
<rich:column>
<h:outputText value="#{_user.name}" /> <!-- CA is done correctly on the name property -->
</rich:column>
</rich:dataTable>

However, when having a generic List of objects, CA does not work.

This occurs for example when converting a Set<User> to a List<User> to provide to the dataTable (due to JSF restrictions to work on List and not on Set) if the convert function uses generics:

@Name("jsfUtils")
public class JsfUtils {
public <T> List<T> asList(Set<T> set)

{ return new ArrayList<T>(set); }

}

<rich:dataTable value="#

{jsfUtils.asList(myBean.userSet)}

" var="_user">
<rich:column>
<h:outputText value="#{_user.name}" /> <!-- CA does not work on the name property -->
</rich:column>
</rich:dataTable>

It would be nice if the type <T> is recognized as <User> by transitivity.
