if your sub process runs from the begin to the end without a safepoint, there will be no persisted information. Remember that jBPM will only persist the process status during a safe point/wait state.
Hi Mauricio, in effect I add two human task in parent proccess and child proccess, in this case process data persist for each one, but when I completed the task, the data is destroyed. In some case the parent process data is persisted.
Is posible persist this data all time?
