I think the warning about the swimlane is normal. "Starting" a process instance is different if there is a task in the start node. I do not know exactly why. I think you need something like this to start the processInstance: | | if (processDef.getTaskMgmtDefinition().getStartTask() != null) { | TaskInstance startTask = processInstance.getTaskMgmtInstance().createStartTaskInstance(); | } else { | processInstance.signal(); | } | I use this code with Jbpm 3.1.1, it may be different for 3.2.
