[Paraview] Custom source glyph error

[Bob Flandard]

Hi Dave,

In the state file, the glyph source is already polyData - created using the
sphere source (sensibly the gui doesn't allow selection of a non polyData
glyph source).

The composite dataset feature will be very useful for multi colored glyphs.

Thanks, Bob
