Hi All,


I'm invoking an ActionHandler on some event (node-enter), but it is giving
this exception : "org.jbpm.graph.def.DelegationException".
Here I'm giving code for action handler class and processdefinition.xml

MyAction.java
__________

package Hello4;

import org.jbpm.context.exe.ContextInstance;
import org.jbpm.graph.def.ActionHandler;
import org.jbpm.graph.def.ProcessDefinition;
import org.jbpm.graph.exe.ExecutionContext;
import org.jbpm.graph.exe.ProcessInstance;


public class MyAction implements ActionHandler {
 private static final long serialVersionUID = 1L;

 public void execute(ExecutionContext executionContext) throws Exception {
 // TODO Auto-generated method stub
 ProcessDefinition processDefinition = ProcessDefinition.parseXmlString("processdefinition.xml");

 ProcessInstance processInstance = new ProcessInstance(processDefinition);

 ContextInstance contextInstance = processInstance.getContextInstance();


 String sum="test";

 contextInstance.setVariable("sum",sum);

 }

}

<process-definition xmlns="" name="Hello4">

 <start-state name="start">
 <event type='node-leave'>
 <action class='MyAction' />
 </event>
 </start-state>

<end-state name="end1">
 </end-state>

</process-definition>
