Task is a wait state where it requires manual action. Task typically represents runtime state of the manual task. So once the task is done the "Task" entry from db is removed. Execution is the common representation of runtime path of execution. So every process instance is an Execution, every sub process is also an Execution. There is execution underneath for tasks as well. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4269648#...
