Well, it would be better to work with the Activiti service interfaces like the TaskService and RuntimeService to add variables. Filtering on the task events you want to handle should be done in the event handler implementation.

Best regards,

Make sense.

Which event handler you are referring to::: " the task listeners" or the "new event api" ?

If you are referring to "the task listeners" than according to my understanding it does not provides event on very activity on a task like changing description… so in the case "new event api" is the only way out..it that correct ?

I believe he means the new event api (not task listeners) indeed.
