[Paraview] loading multiple state-files without hiding and resetting already loaded objects

[Cory Quammen]

Hi Roman,

Sorry I failed to follow up. Did you find a solution to this problem?

This line in your script looks funny to me:

d[props] = pvs.GetProperty(repr, props[0])

Shouldn't props[0] just be props?

Thanks,
Cory
