I'm bumping my head on this. I have a hda with multiple inputs, with a multiparm showing different options for each input dynamically. All working fine. But I want to change the sub-folder/labels for each multiparm to reflect the name of the input, but I can't succeed.
Running into the same problem here. Trying to update the labels dynamically in a Python module but if the multiparm is changed then the reference to the label parm is set to none.
