Rex,

>I have a CEvent subclass in a CListObjEdit form with the oCallingFormListObj and another business object. I can't link to oCallingFormListObj In the CEvent.DefineParticipatingEntities method because oCallingFormListObj does not exist yet. CEvent.DefineParticipatingEntities() executes before CListObjEdit.Init().

That's probably the best place...put the code that you would have placed in DefineParticipatingEntities() in the Init() instead.

Regards,
