[vtkusers] Bug in vtkVRMLImporter?

[Ruediger Tornow]

Hi,

I am using the vtkVRMLImporter to import multiple VRML files. 
It seems that the global variables are not initialized
correctly if the Importer is used several times during one
program run. Even creating new vtkVRMLImporter objects for every
import does not work.
Due to this problem the import fails after reading three to 
five files.
Did anyone encounter this problem before and maybe fixed it?
If so, please let me know.

Thanks,
Ruediger
