Dear Utkarsh,
Thank You very much for Your help. I hope Sebastien will have some idea.
Btw, in a meantime, I discovered one interesting detail. If I set
pipeline source (with widget) as currently active source
(SetActiveSource(...) in pvpython) before I execute code I mentioned
in first message (btw, it should be my_source.SMProxy.InvokeEvent() x
2, instead of active_objects.source.SMProxy.InvokeEvent() x 2 in first
message), everything will work OK. Of course, all this happens after I
switch between different views. Looks like there are some resetting in
pipeline when user switches between views.
Best regards,
Nenad.
