Firing a listener when a task's due date passes

[nmandya]

Hello,
  I am using Activiti 5.17. I have a bunch of user tasks that have a due date sent on them. Is there some way to setup Activiti so that a listener is invoked when the due date of the task has passed and the task has still not been completed? Thanks.

Hi Nagaraj,

due date is just an task's attribute. If you want to handle event use timer boundary event instead.

Hi Martin,
  How can I use a timer boundary event which will fire at a task's due date? My flow is like this - a user task has a due date (which is based on a data received from a form and varies from instance to instance). When the due date of a task is reached, I need to send out email notifications and execute some Java code. If I use a timer boundary event, the time at which the event fires will be hard-coded. As far as I know, the timer event configuration does not allow a process variable to be used to specify the time at which it is to fire. Or am I missing something?

Hi Martin,
  Please ignore my previous response. I see that I can specify a timerDuration with a process variable containing the duration definition. I compute the different between the current time and the due date of the task, convert into a 8601 duration format and set that as a process variable. I then attached this timer to the task and it works as expected. Thanks for the guidance.
