[Paraview-developers] Reader plugin with multiple outputs

[Michael Schlottke]

Hi Phil,

Thanks a lot, this actually solves problem/question no. 1. Do you know why you need the 'id="port0"' attributes? If I omit them, it seems to work just as well.

This works well so far, however, I have a couple of questions:
