pvpython Fetch and multi-block data
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
When multi-block / composite data is loaded using pvpython, Fetch does not return real data. The dataset returned from Fetch has the type of one of the sub-blocks, but it's empty (no cells, points, attribute data, etc.).
In the attached python script that demonstrates this problem, the DataDir should be set to VTKData (not ParaViewData).
