Yes... That's the Only Error.

Because I implemented them. When I debug the IB source it seems like
the Event is not assigned, so it just raises the Exception.
I just did a ShowMessage on the OnError Event, but it never gets
fired.

cached updates?

No, I'm not using Cached Updates. Just a plain TIBOQuery with no
special props set. Only AutoFetchAll = True and FetchWholeRows =
False
