onModify triggered from field change via script
I have a global field that shows status messages after certain tasks are done. I am trying to set it up to clear after a certain period of time, using a script that pauses, and then resets the field to "". I'd prefer not to call that script at the end of every script that sets a message, but instead use a script trigger on the field itself. FM states onModify "triggers a script to run when the value associated with an object changes" but it doesn't seem to work when the field was set via another script, and not directly from the layout. Is there a way to accomplish this?
