Hi there, I'm running Paraview 4.0 RC 2 and trying to make a selection from Python shell. First I used the Find Data dialog with Python trace to get on track and then do it all from the shell.
I have a Legacy VTK source with 2Tuple point data, and would like to extract a selection based on the point data magnitude (Surface_pressure). The following commands are given in the shell: ex = ExtractSelection() sqs = SelectionQuerySource( ProcessID=-1, QueryString='mag(Surface_pressure) >= 100', HierarchicalIndex=-1, FieldType='POINT', HierarchicalLevel=-1) ex.Selection = sqs Show() but I get the following runtime exception Traceback (most recent call last): File "<console>", line 1, in <module> File "/usr/local/ParaView-4.0.0-RC2-Linux-64bit/lib/paraview-4.0/site-packages/paraview/simple.py", line 300, in Show raise RuntimeError, "Could not create a representation object for proxy %s" % proxy.GetXMLLabel() RuntimeError: Could not create a representation object for proxy SelectionQuerySource The Python trace does not help as it does not show any proxy handling. Is this a proxy issue or something else? Thanks.
