I think you need a "dabo.ui.loadUI('wx')" right here.

Ed, Paul, thoughts on this....I was inclined to say that johnClasses
was not in the right directory, but then I saw the stack trace. If it
couldn't find the py file, it would traceback on the import statement.
Could it possibly be something with the cdxml file? I have not used
these yet.....If I had to take a gander, I would say that you imported
johnClasses in the main file, but it is trying to access the
johnClasses class from a different file, which doesn't recognize the
import from the main. Paul, can you put import statements in the
cdxml file?
This is why I like coding by hand...........
