[Paraview] Troubles with exporting selection labels from current ParaView render view

[Utkarsh Ayachit]

Step into "createDataRepresentation" in a debugger. You'll see one of
the arguments is NULL. I suspect its the view. The view isn't setup
yet. Try making the slot connection to a queued connection that way
ParaView gets the change to setup the representation object.
