I just would like to flag a bug or at least I believe so. In vtkMultiblockDataSet, the dash inside names is ignored while using selectors.
my_filter.Selectors = ['test-1']
does the same selection as:
my_filter.Selectors = [‘test1’]
The annoying thing is that if you have a data set with some coordinate in the name (e.g. x_-1, x_0, x_1), selecting only x_-1 would trigger the selection of the x_1 at the same time.
You can find this behaviour in the latest nightly version of Paraview.
Let me know if you know a workaroud to this for the time being
Thank you very much
