    Modifiable Data Model example produces: java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Long when filtering EJB ID column

    JEE 4 Hire Newbie

      Modifiable Data Model example produces: java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Long when filtering EJB ID column

      http://livedemo.exadel.com/richfaces-demo/richfaces/dataTable.jsf?tab=modifiableDataModel&cid=4036

       

      Currently, filtering can only be done on String type fields.

      For example, if I include the Long ID field to CSV_FIELDS, then the following exception is produced.

      What changes do I need to make to org/richfaces/demo/modifiableModel/BaseModifiableHibernateDataModel.java

      so filtering will work on any entity EJB?

       

      Stack trace:
