      I used seam-gen to build a EntityQuery class


      When I am trying to get a DataModel from it using getDataModel()
           


      @DataModel
ListDataModel clients = (ListDataModel) clientList.getDataModel();




      I am getting an NPE.


      Caused by: java.lang.NullPointerException

      Going through the forum, that it could be caused by the ManagedEntityIdentityInterceptor




      http://seamframework.org/Community/CanDataModelBeReplacedWithEntityQuery



      Has this been resolved ? Am I doing something wrong ?


      Thank you for help.
