I am getting this error when trying to remove an entity, that I just previously
loaded(as in the line before).
Find find = new Find(inUserGrpFacility);
getExecMgr().executeEntityManaged(find);
System.out.println("usergroup exists="+ (find.getResult()
!= null));
getExecMgr().executeEntityManagedTx(new
Remove(inUserGrpFacility));
The output of the print statement is: usergroup exists=true
Basically my find and remove calls are just custom command pattern wrappers on
the entity manager find and remove methods. The UserGroupFacility class and
its embedded key class are included below. Assuming that the find works, I am
thinking that there is a bug because the remove is throwing the exception in
the title of my message. I did a trace and there are no SQL delete statements
being executed. Are there any known issues with removing entities with
composite keys?
