Since you say "thread"... that could be part of the problem.

QAIM is not thread safe. And a view has to be the gui thread. As a result,
both the model and the "serial" data feeder need to be in the gui thread.

However, I have heard here of people having no problems with the view and
the model in different threads, but only with a readonly view. Just make
sure that the object writing to the model is in the same thread as the model
itself.
