[Paraview] Custom GUI Not Loading for Plugin

[Michael Jackson]

I have a custom plugin which implements a couple of readers and a couple of filters. I have a custom GUI for each of them which inherits from pqLoadedFormObjectPanel. The filters will load their custom QtPanels BUT it seems the readers will not. The constructors are not ever called. All the code is compiled from what I can tell. The plugins are loading when ParaView launches so I am at a loss as to why they are NOT loading. This is with the 3.12.0 sources for ParaView running on OS X 10.6.8.
  Could someone enlighten me as to some possible reasons why a custom gui panel would NOT get loaded? 

Thanks
