[Paraview] vtkSMProxy saving/restoring

[Nehme Bilal]

Hi again,

I did save and restore the source proxy and 
representations and it's working.
All display properties are saved/restored perfectly, but 
after restoring, changing "color" or "Style" properties 
from the object inspector has no effect. Other properties 
like "visible" or "Transformation" works !

after restoring I called:
vtkSMObject::GetProxyManager()->UpdateRegisteredProxiesInOrder();

but it didn't solve the problem.
