[Paraview] Catalyst edition: no proxy for XMLPPolyDataWriter found

[Lars Bilke]

Dear ParaView users,
I have created a custom catalyst edition (see attached manifest). It is basically the same as the Extras-edition with some parts removed. I have integrated a catalyst adaptor into my application. Everything builds and links fine. Now I want to use a python coprocessing pipeline (see attached script). When running I get the following output:

Generic Warning: In /Users/bilke/code/catalyst/fem-python/ParaViewCore/ClientServerCore/Core/vtkProcessModuleInitializePython.h, line 254
Non-app bundle in install directory not supported

Error: Could not import vtkCommonComputationalGeometryPython

vtkSIProxyDefinitionManager (0x7ff1c9527d70): No proxy that matches: group=filters and proxy=XMLPPolyDataWriter were found.

AttributeError: 'NoneType' object has no attribute ‚GetProperty'


Why is the writer proxy searched in the filters group? It should be in the writers group right?

Thanks for your help!
