vtkStreamingDemandDrivenPipeline ERROR

Hello,

I have a doubt about my visualizer, I hope anyone can help me.

The thing is, my pcl visualizer is implemented using MSVC C++ 2010, pcl 1.6.0, vtk 5.8 and Qt 4.8 (stating with the example http://pointclouds.org/documentation/tutorials/qt_visualizer.php). In my program I receive a signal from a thread in order to update the cloud and the visualizer, this signal is received every 140ms. In general the program works fine, but sometimes a vtk windows appears with the following message :

ERROR: In C:\Projets\PCL\SuperBuild_2010_x64_vtk_qvtk\CMakeExternal\Source\VTK\Filtering\vtkExecutive.cxx, line 776
vtkStreamingDemandDrivenPipeline (0000000002F99790): ProcessRequest invoked during another request.  Returning failure to algorithm vtkTrivialProducer(0000000002F1C650) for the recursive request:
vtkInformation (0000000002FB4AD0)

  Reference Count: 1
  Registered Events: (none)

  FORWARD_DIRECTION: 0
  ALGORITHM_BEFORE_FORWARD: 1
  FROM_OUTPUT_PORT: 0

I was looking for this error but at the moment I didnĀ“t find the solution.

Anyone can help me ?

Advanced thanks.
