Dear Parview users, This question seems trivial - but I do not find any solution on my own!
I have a filter with one mandatory and two optional input ports, and this is how I proceed with it: - Select some data object, then call that filter. It does not open the input port item selection dialog because the one mandatory input is already satisfied. - I want to add one of the optional inputs (or both) - but the "change input" option is greyed! Strange - because for me this would be the logical moment to specify additional input, i.e.: BEFORE pressing the Apply button... - Ok, I press the Apply button thus. Of course the output is not what I want because the optional inputs were missing... - However, now I can choose also the "change input" option - and I do so. I select the two optional inputs. But now nothing happens any more - and now the Apply button is grey, so no way to trigger an update of the output! To me this does not look very logical, so I assume that I am missing some point... The other "intuitive option" would be to select all the desired input items, and only then open the filter. However this is impossible from the beginning because now the filter is already greyed in the menu as being "not applicable"! Thanks for any helpful hints! Regards, Cornelis Bockemühl
