Hello dear Paraview Developers!
I am trying to extend the GUI and I need to access my filter
`pxm->GetProxies("filters", "MyFilter", render_view_proxies);`
However, it does not work. There is no group as filters inside, only filter\_prototypes. What should I use?
Best regards

This looks correct to me. Is “MyFilter” actually available in the filters of ParaView through a plugin or something ?

Yes, and more than that, it is launched and is in the pipeline monitor

More than that,
pxm-\>GetProxies(“filters\_prototypes”, “MyFilter”, render\_view\_proxies);
It works but
vtkSMPropertyHelper dont set anything on them
what could be wrong?
Maybe update vtk is missing (or is it inside helper?)

Could my filter be on another vtkSMSessionProxyManager than
`vtkSMSessionProxyManager* pxm = pqActiveObjects::instance().proxyManager();`
?
