Hi Malcolm,
   
  Is there a need to create DBEntity and ObjEntity for the superclass? 
   
  Regards,
  James

  Hi James,

Yes you can. In the modeler, you define a common "Custom Superclass" under
the DataMap "Entity Defaults". Make sure you custom superclass extends
DataObject, and add your common attributes. You generated classes will then
extend your common superclass.

Make sure your DB Entities support these attributes.

regards Malcolm Edgar
