[Paraview] Python script not working after updating to 5.1

[Heather.Sheldon at csiro.au]

I have just updated from Paraview 4.3.1 to 5.1.0 and am having trouble with a Python script that no longer works correctly.

The attached script cycles through exodus files in a given directory, and for each file plots a surface plot of GlobalElementId overlain with a threshold plot of 2 other cell variables (one after the other), producing a screenshot of each image. This was working just fine with v4.3.1, but when I run it in 5.1.0 it fails to plot  GlobalElementId except for the first file, and fails to show the scalar color bar for any of the files. What has gone wrong?

Regards.
Heather
