How can I send messages to the maya user depending on the current tool settings? I tried to use “print” from the otl's hdaModule using attributes callback script but for buttons it only seem to run once automatically when the asset and not when it's pressed. For other parameters like menus it doesn't seem to do anything at all.

NM. Don't know what I did beside restart Maya but now I can see my hdaModule prints in the script editor and they do read the attribute editors settings so it's all good.
