[vtk-developers] [vtkuser] vtkAssignAttribute returned failure for request: vtkInformation

[victor sv]

Hello all,

i'm lost with the following error ... :

ERROR: In /media/Novo volume/VTK6.0.0/Filters/Core/vtkAssignAttribute.cxx,
line 275
vtkAssignAttribute (0x5b30840): Data must be point or cell for vtkDataSet

ERROR: In /media/Novo
volume/VTK6.0.0/Common/ExecutionModel/vtkExecutive.cxx, line 754
vtkCompositeDataPipeline (0x375de50): Algorithm
vtkAssignAttribute(0x5b30840) returned failure for request: vtkInformation

I'm using VTK6 and It happens when I use vtkAppendFilter to visualize
multiple meshes at same time.

Does anyone know why it could be happening?

Thanks :)
Víctor.
