[Paraview] VTK Writer

I've just noticed that none of my writer plugins are working from the GUI.
 They appear but when trying to write I get the following output:

Failed to create writer for:  "/path/to/file.mytype"
ERROR: In /ParaView/ParaViewCore/ServerManager/vtkSMWriterFactory.cxx, line
374
vtkSMWriterFactory (0x8b3d8a0): No matching writer found for extension:
mytype

Is this intentional and do we need to put in hints for each writer now?  I
thought the type just went in the pqXML file.

Thanks,
Paul
