Q: Anyone knows this error message?

[Mirco Mueller]

Greetings vtk-gurus!

During runtime of a vtk-program I get this error

    ERROR In vtkOpenGLPolyDataMapper.cxx, line 133
    vtkOpenGLPolyDataMapper (0x107043c0): No input!

when I do a

    ren->AddActor( some_actor );

    Any idea what could cause this? The mapper is set up with SetInput()
method before the actor gets properly set up with the SetMapper()
method.

Thanks in advance for your time and kind advice!

Best regards...

Mirco
