[Paraview] Please help!! How to force Render() from a reader

[Olesen, Mark]

On a related tangent to the rendering issue:
What method is needed to get the 3d view window to refresh.
I have a customized reader panel with a few Qt checkboxes.
When I select, for example, "Add Labels", the slot sends it to the server manager and it is correctly updated.
However, the text labels themselves don't appear in the window until I do something else like resizing the window, clicking something, etc.

What method should be I using?
