[vtkusers] vtkGenericDataObjectReader, error handling

[Michal Szostakiewicz]

Dear Bill!

Thanks so much for your answer! (although I must say I'm a little bit
surprised there is no other way to check that)

I looked at this ErrorObserver class, but is there any way to use this
technique in Java wrapper?

What I basically need is just to "ignore" all the errors... Maybe there is
some "built-in" vtkCommand to do that?


Best regards,
Michał
