Summary:                    vtkOpenGLGPUVolumeRayCastMapper PreRender end Error
on readding volumes
Description: 
First off, I am using the Java Wrappers of vtk, if this might be of any use.

Problem:
I have a Program where the user can switch between the volumes to be rendered.
For this I call
renderer.RemoveAllVolumes();
...
volume = getVolume(); // this will actually get the same volume, they are
cached, if the user decides to display the same volume again
...
renderer.AddVolume(volume);

If using the vtkOpenGLGPUVolumeRayCastMapper, the user first adds a new volume,
than goes back to the original volume, I get the following error:

PreRender end (x502) Invalid Operation

which I have tracked down to originate from the vtkOpenGLGPUVolumeRayCastMapper.

This does not crash the System, it still works fine.

So far I could only recreate this on a Linux System, maybe later I can try it on
a Win System.
