[Paraview] Singleton vtkObject multiple SMProxies

[Biddiscombe, John A.]

Dave,

Thanks, I see the adaptive options stuff. You are manually creating the SMAdaptiveoptionsProxy - which is ok if you have a custom panels - I do for one window, but the others are autogenerated, and I want them to pick up the same proxy (and custom panel for the sub proxy) - I tried creating a singleton proxy but can't make it work and on plugin load it instantiates one, then when I try to use it in a filter - the connection Id changes when instantated the second time and paraview gives me grief.

to try to explain better ...

you have 
<AdaptiveOptionsProxy name="AdaptiveOptions" class="vtkAdaptiveOptions">
...
</AdaptiveOptionsProxy>

which is nice, it instantiates a vtkSMAdaptiveOptions which is a custom SMProxy. All is well, but when I try to use this as a sub proxy on a filter. Paraview ain't happy

    <SourceProxy name="Annoyingfilter" class="vtkAnnoyingFilter">
      <SubProxy>
        < AdaptiveOptionsProxy 
		name = blah blah
This bit ain't working in here.	
        </ AdaptiveOptionsProxy >
      </SubProxy>

I can't make it use my custom proxy as a filter param sub proxy (or use my panel either)

any ideas?

JB
