[vtk-developers] Crash with vtkCompassWidget

[Ken Martin]

I already checked in a fix for this. Clearly Get methods should not crash.
It did already create a default rep before being rendered it just did not do
that prior to someone invoking one of the set/get methods in question.

Thanks
Ken

I'll just add that no other VTK class behaves like this.  It shouldn't 
crash this way.  At least the getters should check for the WidgetRep and 
return 0 or something if it isn't set and can't be set to a reasonable 
default.

cheers,
