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); | | } | | } | __________ processdefinition.xml ________________ | <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> | ___________ Thanks & Regards Manjula View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4130268#...
