      Hi
      I have some processes defined and i have an object that is created in the first node and seted as a process variable using setVariable method
      The problem is when I try to load the object in the next node i get an DelegationException caused by ClassCastException
      My object class is:

      public class ContentPackage implements Serializable{

 private static final long serialVersionUID = 2175042348064562851L;
 static Logger logger = Logger.getLogger(ContentPackage.class);

 private transient Document docPublish;
 //private List instancesContentManagement;


 public ContentPackage(String idContent, String type){

 docPublish = XMLHelper.createDocument();
 Element root = (Element)docPublish.appendChild(docPublish.createElement("documentPublish"));

 Element header = docPublish.createElement("header");
 root.appendChild(header);

 Element idCont = docPublish.createElement("idContent");
 idCont.appendChild(docPublish.createTextNode(idContent));
 header.appendChild(idCont);

 Element contentType = docPublish.createElement("contentType");
 contentType.appendChild(docPublish.createTextNode(type));
 header.appendChild(contentType);

 Element date = docPublish.createElement("createdDate");
 date.appendChild(docPublish.createTextNode(ProjectUtil.dateFormat(new Date(), "dd-MM-yyyy HH:mm:ss.S")));
 header.appendChild(date);

 Element body = docPublish.createElement("body");
 root.appendChild(body);

 }

 public Document getDocPublish() {
 return docPublish;
 }

 public void setDocPublish(Document docPublish) {
 this.docPublish = docPublish;
 }
}


      I thought that the problem was that the document (w3c) field was not serializable and i put the filed transient and defined wrtiteObject and readObject methods, but nothing.. the same error...

      ANY IDEA ?????

          PLEASE post a UNITTEST with embedded processdefinition to demonstrate the problem. I can drop that in my ide, run/debug it real quick then.

            The process definition

            <?xml version="1.0" encoding="UTF-8"?>

            The extractEventHandler 
            ublic class ExtractEventHandler implements ActionHandler{

 private static final long serialVersionUID = 1L;

 //Colocar aqui la direccion del servlet que genera el XML del evento en DIRECTOR
 private final String xmlServletAddress = "http://192.168.0.174/SinFlash/ContentMgmt?eventID=";

 /**
 * Metodo que se llama cuando se ejecuta el Handler del proceso al cual pertenece
 */
 public void execute(ExecutionContext executionContext) throws Exception {

 String eventId = (String) executionContext.getContextInstance().getVariable("id");
 ContentPackage doc = new ContentPackage(eventId, "event");
 Document document = doc.getDocPublish();

// Doing something with that Document

doc.setDocPublish(document);
 executionContext.setVariable("contentPackage",doc);
 executionContext.leaveNode();
 }


            The contentPackage (the class i want to set as variable) 
            public class ContentPackage implements Serializable{

 private static final long serialVersionUID = 2175042348064562851L;
 static Logger logger = Logger.getLogger(ContentPackage.class);

 private transient Document docPublish;
 //private List instancesContentManagement;


 public ContentPackage(String idContent, String type){

 docPublish = XMLHelper.createDocument();
 Element root = (Element)docPublish.appendChild(docPublish.createElement("documentPublish"));

 Element header = docPublish.createElement("header");
 root.appendChild(header);

 Element idCont = docPublish.createElement("idContent");
 idCont.appendChild(docPublish.createTextNode(idContent));
 header.appendChild(idCont);

 Element contentType = docPublish.createElement("contentType");
 contentType.appendChild(docPublish.createTextNode(type));
 header.appendChild(contentType);

 Element date = docPublish.createElement("createdDate");
 date.appendChild(docPublish.createTextNode(ProjectUtil.dateFormat(new Date(), "dd-MM-yyyy HH:mm:ss.S")));
 header.appendChild(date);

 Element body = docPublish.createElement("body");
 root.appendChild(body);

 }

 public Document getDocPublish() {
 return docPublish;
 }

 public void setDocPublish(Document docPublish) {
 this.docPublish = docPublish;
 }

}


            The transformEventHandler 

            
public class TransformEventHandler implements ActionHandler{

 private static final long serialVersionUID = 1L;

 public void execute(ExecutionContext executionContext) throws Exception {

 System.out.println("================ TRANSFORM EVENT HANDLER ===================================");
 ContentPackage contentPackage = (ContentPackage)executionContext.getVariable("contentPackage");
 Document doc = contentPackage.getDocPublish();

 System.out.println("XML");
 System.out.println(XMLHelper.serializeDocument(doc));
 executionContext.leaveNode();
 }

}


            The Exception

              Rafael...
              ExtractEventHandler:

              Document document = doc.getDocPublish();
executionContext.setVariable("contentPackage",doc);

              TransformEventHandler: 
              ContentPackage contentPackage = (ContentPackage)executionContext.getVariable("contentPackage");

              Amigo, revisa tu código :)
