Hello,

I am having some issues in how to call a class using Delegate expression inside a UserTask in activiti , this is what i did :

-Called my Task Listener like this with a create Event using Delegate Expression ${DelegationTaskListener}

-This is my class:

package com.order;

import java.util.Arrays;
import org.activiti.engine.delegate.DelegateTask;
import org.activiti.engine.delegate.TaskListener;
import org.alfresco.service.ServiceRegistry;
import org.alfresco.service.cmr.repository.NodeRef;
import org.alfresco.service.cmr.repository.NodeService;
import org.alfresco.service.cmr.security.PersonService;

public class DelegationTaskListener implements TaskListener {

private ServiceRegistry serviceRegistry ;

public void setServiceRegistry(ServiceRegistry serviceRegistry){
this.serviceRegistry = serviceRegistry;
}

@override
public void notify(DelegateTask delegateTask) {

String userName = "admin";
System.out.println("userName "+userName);
NodeService nodeService = serviceRegistry.getNodeService();
PersonService personService = serviceRegistry.getPersonService();
//do stuff
}
}

-and this my bean declaration in service-context.xml:

<bean id="DelegationTaskListener" class="com.order.DelegationTaskListener">
<property name="serviceRegistry">
<ref bean="ServiceRegistry" />
</property>
</bean>

what is missing???
