[Paraview] Trouble with "information_only" GUI property in paraview filter

[Yumin Yuan]

Hi Alex,

You can add the following to your xml to see if it helps.

show="1"

If this property does show up after adding that, it should be
displayed as disabled since it is read-only. If it does not help, this
could be a bug.
