use this code to end the taskInstance:
| public static void main(String[] args) {
| JbpmConfiguration config=JbpmConfiguration.getInstance();
| JbpmContext jbpmContext=config.createJbpmContext();
|
| TaskInstance ti = jbpmContext.getTaskInstance(18);
|
| ti.end("to result"); // this will go to the Decision node,cause
exception
| //ti.end("need modify form"); // if use this test, everything is ok.
| jbpmContext.close();
|
|
| }
|
when the process go to the Decision node , cause error.
