[jboss-user] [JBoss jBPM] - Re: Error in node-->TaskNode

[harderwu]

sorry!
that is misspelled!!
ProcessDefinition: 

 <start-state name="a">
  |        <transition name="tra" to="b">
  |        </transition>
  |    </start-state>
  |    <task-node name="b">
  |       <task name="first">
  |          <assignment class="com.test.assignment.PartMaster" config-type="bean">
  |             <groupName>leader</groupName>
  |          </assignment>
  |               </task>
  |            <transition name="tra2" to="c">
  |                </transition>
  |          </task-node>	 
  | 
  |  
first,I can get a object of transition that name is "tra",
but there is an error when i get the object of tasknode by the transition.getTo()
TaskNode tasknode = (TaskNode) transition.getTo();	
there is not the error if i get the object of node by by the transition.getTo()
Node node = (Node) transition.getTo();
i know the node is the father class of the tasknode, i had seen the code in the exmaple of org.jbpm.test:
public void testTaskNode() {
    ProcessDefinition processDefinition = ProcessDefinition.parseXmlString(
      "<process-definition>" +
      "  <task-node name='t' signal='first-wait' create-tasks='false'>" +
      "    " +
      "      " +
      "    " +
      "    " +
      "    " +
      "  </task-node>" +
      "</process-definition>"
    );
    
    processDefinition = saveAndReload(processDefinition);
    
    TaskNode taskNode = (TaskNode) processDefinition.getNode("t");
}
