Hi Alejandro,
I did not drag a process over the ImageContainer, I did it the other way round: I dragged the container icon over the Debayer process. (A converse dragging doesn't do anything.) When compared to other processes, e.g. PixelMath, everything is all right and working fine.
There is a BatchDebayer script, I know. Maybe this script has been written to overcome the difficulties I've been facing with ImageContainer applied to the Debayer process. But what is different with Debayer, so that the general methodology of PI (processes which do not have a dialog based multi-file input can be fed by a ProcessContainer) does not hold in this case?
Viele Gruesse
