[vtkusers] ActiViz | Garbage Collection unhandled exception

[franko]

When running my application (ActiViz.Net, C++), I get the following error:

Exception was unhandled
error: could not get registered type - mteIndex='4294967295' classNameKey=''

I've read the following threads in VTK-Users archive:

- ActiviZ | Strange Error | DavidCole
- Dispose to vtk objects
- ActiViz vtkImagePlaneWidget

My application draws a model of connected pipes with annotations. There are
times when the code needs to redraw the model. I use the same vtkRenderer
and vtkRenderWindow, but I execute renderer->RemoveAllViewProps() before
adding new actors and assemblies to the renderer.

I'm wondering if .Net has deleted something that VTK thinks is still there.
Any ideas on how to troubleshoot this? 

Thanks,
Frank Opila
