    Auto generated composite key generates Attribute required exception

    Anthony Yulo Newbie

      I have a composite/primary key composed of two attributes. One of the attributes is supposed to be only populated by a trigger (im using MySQL).  Its not actually a sequence, but the function trigger takes care of supplying its values.


      However, on the java side, since it is a primary key, it is supposed to be not nullable.  So everytime I save an entity object, the application complains, saying it requires a value for one of the attribute that is auto-generated.  Temporarily I have supplied an arbitrary value to the attribute, because eventually it will be overwritten by the trigger. 


      Any ideas?
