CA should recognize the object type when using generics in rich:dataTable value
-------------------------------------------------------------------------------

                 Key: JBIDE-4903
                 URL: https://jira.jboss.org/jira/browse/JBIDE-4903
             Project: Tools (JBoss Tools)
          Issue Type: Feature Request
          Components: jsp/jsf/xml source editing
    Affects Versions: 3.1.0.M2
            Reporter: Julien Kronegg
            Priority: Minor


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.
