I have a question regarding reminders. I would like to set a reminder to be sent to a user at a certain date (a date that is stored in a field on the form that is submitted). But in the settings of the Reminder I can only set the reminder to be fired after a fixed number of days (say after 2 days or 10 minutes - in my scenario I would like to set a date like 5/9/2008).
You want the reminder to be sent on an absolute date, and not on a date that is relative to the time when the task was assigned.
I'm not sure if this is the best way, but you could create a subprocess that sends an email, and has as input values all the pertinent information (date the email should be sent, task ID, user ID, URL to the task, etc.). The subprocess uses the Email service to send an email reminder.
Make the render process of the form variable that is used with the Assign Task operation call the subprocess.
It's not a 'real' reminder, but it accomplishes the same effect.
Thanks for your answer - You describe the exact functionality I would like to have.
I believe that your solution might work - I would just want to use an event (Task Assigned) instead of the Render-Form as the case could be that the user wouldn't render the form before the reminder would reach the absolute date. Hence the email would never be sent.
