Extract Block fails when used with temporal data
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
A user discovered that the Extract Block filter can fail when you attach to it a filter that requests multiple time steps. It appears that the executive fails to iterate the call over each time step. To replicate, do the following.
- Load can.ex2. Apply.
- Add the Extract Block filter. Select a block. Apply.
- Add the Temporal Interpolator filter to Extract Block. Apply.
When you hit apply for the Temporal Interpolator filter, you get a lot of the following error and no data.
ERROR: In /Users/kmorel/src/ParaView3/VTK/Filtering/vtkDemandDrivenPipeline.cxx, line 828 vtkCompositeDataPipeline (0x28e25960): Input for connection index 0 on input port index 0 for algorithm vtkExtractBlock(0x28e25270) is of type vtkTemporalDataSet, but a vtkMultiBlockDataSet is required.
