> 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.
