Hi,

I am getting classcastException while calling the action handler in the transition like this.

 <transition name="Check Duplicatelist" to="Check Duplicatelist">
 <action class = "com.sample.action.AutomatedAsyncflowHandler">
 <message>CheckDuplicatelist</message>
 </action>
 </transition>

my action handler is

package com.sample.action;

import org.jbpm.graph.def.ActionHandler;
import org.jbpm.graph.exe.ExecutionContext;

public class AutomatedAsyncflowHandler implements ActionHandler {

 private static final long serialVersionUID = 1L;

 /**
 * The message member gets its value from the configuration in the
 * processdefinition. The value is injected directly by the engine.
 */
 String message;

 /**
 * A message process variable is assigned the value of the message
 * member. The process variable is created if it doesn't exist yet.
 */
 public void execute(ExecutionContext context) throws Exception {
 context.getContextInstance().setVariable("message", message);

 System.out.println("i am in the MessageActionHandler" + message);
 }


}

this exception is coming for me
