[vtk-developers] vtkPolyDataAlgorithm - returned failure for request: vtkInformation ?

[Jana Sefcikova]

Hi all, my algorithm renders correct result, but in console I have
following error :

ERROR: In /Developer/VTK 5.10/src/Filtering/vtkExecutive.cxx, line 756

vtkStreamingDemandDrivenPipeline (0x10734fc00): Algorithm
vtkWatershed(0x10732f110) returned failure for request: vtkInformation
(0x107351280)

  Debug: Off

  Modified Time: 1074

  Reference Count: 1

  Registered Events: (none)

  Request: REQUEST_DATA

  FROM_OUTPUT_PORT: 0

  ALGORITHM_AFTER_FORWARD: 1

  FORWARD_DIRECTION: 0

The algorithm derives from vtkPolyDataAlgorithm and implement only
RequestData method, add an array to input and shallow copy input  to output.

What it can mean?


Thank you.

Jana
