[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - MultipleDataSelection and problem with merge

[yohann49]

Hi everybody !

I currently develop an enterprise application able to manage a client's account(he could see his orders, line orders and product in assocation with those lines). I use netbeans, glassfish, seam and hibernate. I want to post many datalist with link. I use Conversation and Session for that. I want to know if it possible to use many DataModeleSelection.

Otherwise theirs is a problem with my ServerManger : 

first page : login
second : list of orders
third : list of lines
forth : list of server concerned by the lines


  | 
  | Code of my forth page 
  | Stateful
  | @Name("ServerManager")
  | 
  | public class ServerManager implements ServerManagerLocal
  | {
  |    
  |         
  |     @In
  |     private EntityManager em;
  |     
  |     @DataModel
  |     @In(required=false) @Out(required=false)
  |     List<Server> servs;
  |     
  |     
  |     @DataModelSelection
  |     @Out(required=false)
  |     private Server currentServer;
  |     
  | 
  |     private OrderLine myOrderLine;
  |        
  |     
  |     @Factory(value="servs",scope=CONVERSATION)
  |     public void searchServers (){
  |               
  |         
  |         servs = myOrderLine.getServers();
  |         
  |        
  |     }
  |     
  |     
  |     @Begin(join=true)
  |     public void viewParameters(OrderLine orderLine){ 
  |         System.out.println("on rentre dans le server manager");
  |         myOrderLine=em.merge(orderLine);
  | 
  |             
  |     }
  |     
  | 
  |         
  |     
  |     
  |     @Remove @Destroy
  |     public void destroy(){
  |     }
  | 
  |     public List<Server> getServs() {
  |         return servs;
  |     }
  | 
  |        
  | 
  |     public Server getCurrentServer() {
  |         return currentServer;
  |     }
  | 
  |     public void setCurrentServer(Server currentServer) {
  |         this.currentServer = currentServer;
  |     }
  | 
  |     public OrderLine getMyOrderLine() {
  |         return myOrderLine;
  |     }
  | 
  |     public void setMyOrderLine(OrderLine myOrderLine) {
  |         this.myOrderLine = myOrderLine;
  |     }
  | 
  |     
  | }
  | 
  | 

And in my debug page I have this exception
