As soon as a user accepts a task, I need to change the value of a pv!. I saw a l

What are you using the set value for? Can you not execute a report at the point of time where this value is required on the task report and identify what the task status is, i.e. Assigned or Accepted and use this as an indicator accordingly?

Not exactly. I am tracking the status of a request as it progresses in its lifecycle. Certain user actions can change the request status. An user accepting a task should change the status to "Accepted". Now the status I am talking about is the status of a custom variable I use for reporting and is no way tied to the Appian Process or task statutes. Is there a way to achieve this?

Hi padmanabhanv, Consider this solution if usage of js/ jquery is allowed. Create a dummy user input task and write a autosubmit event on load of the form, such that the form gets submitted automatically whenever someone accepts the task. Also capture the tp!owner of this task. Now place a script task which updates your status variable, or else this could be done in the dummy user input task itself. Now have the original task after this in an activity-chained fashion.

And finally provide the assignment of original task to the tp!owner captured in the dummy user input task.

@ sikhivahans - Thats a cool idea. Thank you

For a more Tempo-friendly solution, I would try using the getTaskAcceptedTimestamp() function in the Task Smart Services plugin, and then (in a rule event) use APN_isEmpty on the pv you're saving the timestamp into to check for that status change.
