Enable support for DataModelSelection when used with entiy-query
----------------------------------------------------------------

                 Key: JBSEAM-1287
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-1287
             Project: JBoss Seam
          Issue Type: Feature Request
          Components: Framework
            Reporter: Brian Smith


It would be nice to be able to match up a DataModelSelection with a DataModel that is provided by an entity-query.  As of now a deployment error is thrown.

Use Case:  If a data table is driven by an entity-query, the only way currently to select a row is by passing the var using the Extended EL Seam provides.  The extended EL is not compatible with some component libraries (Trinidad) and it is very ugly to go through component bindings to get the current value of the selected row.  It would be nice to hook a DataModelSelection to the entity-query.

Something like this
-components.xml-

  <framework:entity-query name="allUsers"
                               ejbql="select u from User u"/>

-facelets page-
[code]
            <tr:table id="user_table" value="#{allUsers}" var="user">
                <tr:column id="user_column">
                    <f:facet name="header">
                        <tr:outputText id="user_header" value="Customer"/>
                    </f:facet>
                    <tr:commandLink id="user_link" text="#{useruserName}" actionListener="#{attachUser.done}"/> 
                </tr:column>
            </tr:table>[
/code]

-Seam Bean-

@DataModelSelection("allUsers")
List <User> userList;
