What you are likely doing is creating a component with a NIL owner and IBO
doesn't like this. You should use the TIB_Session of the thread as the owner
of the component when it is created and then you won't have to use
SetSession.

Ideally it should work as you are attempting and I will take a closer look
to see what is happening here. Consider this logged as a bug.
