[Paraview] GetSources() fails with Custom Filters

[m.c.wilkins at massey.ac.nz]

Hi,

Perhaps I am doing something wrong, because I am getting different
behaviour to you Utkarsh.

I have not tried the current git-master, just 3.6.2 and 3.8.0.

With 3.8.0 GetSources() only works if I make the custom filter, then
restart paraview and apply it.  If I apply the custom filter
immediately after making it, GetSources() craps out with the KeyError
as below.

With 3.6.2 GetSources() always craps out, regardless of whether I
restart paraview or not.

To make the custom filter I just make two filters, select them both,
go to Tools -> Create Custom Filter, give it a name, then hit Next
Next Finished.  I don't do anything more than that.  Is there some
other step I am missing perhaps?

Thanks

Matt Wilkins
