[Paraview] [EXTERNAL] Re: PV 4.2.0 Color legend disappearing

[Scott, W Alan]

Perfect!!

I have replicated this bug, and repeated it a few time.  Breaks every time.  Thanks Armin for writing it up!!  I just targeted PV 4.3, out next month for the fix.

I actually realized that the state files I provided used a rather large dataset that I didn't provide.

However, I actually have been able to reproduce the bug now consistently when using an explicit server/client setup.

Here the steps to trigger the disappearance to the color legend:
1) run pvserver (e.g. on the local machine)
2) Connect to pvserver
3) Add a source (e.g. cylinder or sphere)
4) Change the displayed quantities, i.e. the color array, about 5-10 times. Usually I can display each color array at least one time, but when switching several times between them the legend disappears.

As said, without using an explicit connection to pvserver I cannot trigger this bug.

I attached again two state files, this time using the cylinder source only.

Thanks for taking care of this!
