I have an all-service-task(ST) workflow with a waitTask to force activiti to perists data( and to avoid stack overflows). ST1 –> ST2 –> ST3 –> ST4 –> WaitTask –> Exclusive Gateway –> (if TRUE –> End, else –> Point back to ST2)Each of my service tasks are complex; as they persists several hundred records into database. The problem is, the data is not committed until the process hits waitTask. Though I am not sharing the same transaction manager. How can I make the transactions created by Activiti and by my service task commit independent.

Invocation:
ProcessInstance pi = runtimeService.startProcessInstanceByKey("customProcess",processContextMap);
Execution execution = null;
while ((execution = runtimeService.createExecutionQuery().processInstanceId(pi.getId()).activityId("waitStateReceiveTask")
.singleResult()) != null) {
runtimeService.signal(execution.getId());
}
