Is VF.py your code?

If so, you have a bug in the code.

If not, then *possibly* there is a bug in the ViewerFramework package. Or more 
likely you are aren't using it correctly. My guess is that you haven't 
initialised the framework correctly. Read the documentation for it.

Read the documentation.
Check your code.
Google for the error message and see if other people are having it.
What are you doing that leads to the error? Do something different.
If there is a forum specifically for the ViewerFramework package, ask there.
If not, write to the author.
