Loading state file that references an unstructured grid or uniform rectilinear grid pops up error message
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
The collaboration branch merge introduced the following regression:
ParaView nightly build (pv commit 0e9d5b39), local server, Linux 64-bit.
- Sources / Wavelet. Apply
- File / Save State / filename: foo.pvsm
- File / Disconnect
- File / Load State / filename: foo.pvsm
=> the following error message is raised:
VTK/Filtering/vtkDemandDrivenPipeline.cxx, line 727 vtkCompositeDataPipeline (0x34e4ef0): Input port 0 of algorithm vtkOpenGLGPUVolumeRayCastMapper(0x364b000) has 0 connections but is not optional.
A similar error message is raised if the state file references an unstructured grid (Apply "Clean to Grid" before saving state):
VTK/Filtering/vtkDemandDrivenPipeline.cxx, line 727 vtkCompositeDataPipeline (0x4142e60): Input port 0 of algorithm vtkUnstructuredGridVolumeZSweepMapper(0x30b4e20) has 0 connections but is not optional.
This does not happen for e.g. a polygonal mesh.
Neither of these errors were raised with PV 3.11.0.
