Hey Zoli,

I don't have any code in this method. I only have code in
objectEventPerformed ().

I commented out all the contents and the same exception is occuring.
Something outside the scope of objectEventPerformed is throwing the
***Unhandled and unknown exception was thrown in BON2Component
ObjectEvent*** exception. I have also experienced the same problem when
trying to handle the OET_RegistryChanged event when OET_ObjectCreated is
sent as well.

I don't understand what using the consoleMsg has to do w/ what I'm doing
since I'm not trying to write to the console?!?!?! I just want to import
an existing model.

Thanks,
