You can try the code below and check if it works. | ProcessInstance subProcessInstance = ctx.getJbpmContext() .getProcessInstanceForUpdate(subprocessInstanceId); | | //get the task management instance of the process instance | TaskMgmtInstance taskManagementInstance = subProcessInstance.getTaskMgmtInstance(); | | //find the unfinished tasks | Collection<TaskInstance> taskInstances = taskManagementInstance.getUnfinishedTasks(subProcessInstance.getRootToken()); | | //get the task instance of your interest | TaskInstance taskInstance = /*Some how find out the TaskInstance that we should be executing from taskInstances collection */; | | //finish the TaskInstance | taskInstance.end(); | If you can provide the Jpdl snippet that creates problem, and few more lines of your code then that will be helpful to debug the problem with you code.
