    Question on Injection an Context

    Hannes Schulz Newbie

      Hi,

      i have some trouble propably because of a misunderstanding with resrouce injection.

      I have a Stateful bean in conversation scope. The bean is responsible for managing some user input. The user data is stored in an object (calculation) which is injected in the manager bean.

      @Stateful
      @Scope(ScopeType.CONVERSATION)
      @Name("manager")
      public class CalculationManagerBean implements CalculationManager {
      
       @In Calculation calculation
      }
      



      Now on a special page i want to manipulte a list wich is an attribute of the calculation object. I thought a component with ScopeType.PAGE is a good candidate to offer the methods to add change and remove list elements. So i wrote a component which injects the calculation object.

      @Name("listmanager")
      @Scope(ScopeType.PAGE)
      public class ListManager implements Serializable{
      
       @In
       Calculation calculation;
      
       @DataModel
       List<ListItem> list;
      
       public void addItem() {
       list.add(item);
       calculation.setList(list);
       }
      
      


      I want to save the manipulated list in the calculation object whenever the list changes. The problem is that if i call the setter method it has no effect on the calculation method.

      I guess is accociated with the scope, so conversion is longer than page. But i dont have a proper solution or a better way to achieve what i want.

      Help would be great.
