| <task-node name="chief examine">

| <task name="chief examine">
| <description>
| ????
| </description>
| <assignment class="demo.workflow.assignment.ChiefAssignment"></assignment>
| <controller>
| <variable access="read" name="reimbursementId" mapped-name="rid"></variable>
| </controller>
| </task>
| <transition to="requester fix the reimbursement form" name="need modify form"></transition>
| <transition to="decision" name="to result"></transition>
| </task-node>
|
| <decision name="decision">

| ????
| </description>
| <handler class="demo.workflow.action.DecisionProcess"></handler>
| <transition to="handle result" name="to result"></transition>
| <transition to="boss examine" name="to boss examine"></transition>
| <transition to="financial affairs process" name="to financial affairs process"></transition>
| </decision>
|
|
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.
