[Paraview-developers] information_only property doesn't update, please help

[iusadhfoias sidufasipudf]

Hi Cory,
what is the reason, why you ignore my emails?

run within seconds, and I described the problem in sufficient detail. In
this list many questions are answered that leave out important details
again and again. But my question is ignored. What is wrong with my problem
description?
