hi all

I have a task in a process. By mistake i have performed the task which i should have not done. Is there a way by which i can rollback the task which i have done. In other words is there any way where i could have a "UNDO" button in my task list, which will rollback the changes made. Does jbpm engine has built in support for this. JBPM EXPERTS please help...

thanks in advance
