Thanks Mauricio,
I must implement a ProcessEventListener? This interface has no methods where i can get the start date of the task, end date of the task. Do you have any sample of how implement this listener?
This information should be stored in another table?
I noticed that some of the functionality of jbpm 5.3 is "Pluggable strategies for task cleanup". So i will not be able to use the task table to keep the history, right?
I appreciate your help.
