[Paraview] Problem with setting the scalar range for the lookup table of a newly added source

[Cory Quammen]

Anton,

Maybe try adding

stc->getProxy()->UpdateVTKObjects();

after setting the scalar range?

It's always possible there is a bug in the rescaling logic. Do you
have a minimal code example you could post to make it easier to track
down?

Thanks,
Cory
