somebody else had same problem - won't trigger after 1st time...
Finally got automator and calendar to work.
I was able to accomplish this as well, but I'm having a devil of a time getting the workflow to repeat after the first event.
The calendar repeats the event, but does not trigger the workflow app.
For example, I want a workflow to be triggered on the 1st of every month.
I go to the workflow in Automator and schedule it for September 1st, which adds a calendar entry in the "Automator" Calendar on my Mac.
I then edit the Calendar entry to repeat every month, and I see it add the event to the 1st of every month thereafter.
On September 1st the Workflow executes beautifully but then October 1st rolls around and nothing happens.
Its driving me mad.
