    Maintaining a variable in Session Context

    Naresh Bhatia Newbie

      I am writing a banking application where the user has multiple accounts. In the user's session, I need the concept of the currently selected account. The account selection can be changed on any page - sometimes by clicking a row in a data table and at other times by selecting an account from a drop down list. What is the best way to implement this?


      Currently I have an account list page that uses a data table to select an account:


      @Name("accountListController")
      @Scope(ScopeType.CONVERSATION)
      public class AccountListController implements Serializable {
          @DataModel(scope=ScopeType.PAGE)
          private List<Account> accounts;
      
          @DataModelSelection
          @Out(required=false)
          private Account selectedAccount;
      }
      



      All other pages use a drop down to select an account. For example:


      @Name("paymentController")
      @Scope(ScopeType.CONVERSATION)
      public class PaymentController implements Serializable {
          @Out(required=false)
          private List<Account> accounts;
      
          private Account selectedAccount;
      



      As you can see, here selectedAccount is not the same as the selectedAccount outjected by the AccountListController? Is there a way to factor out selectedAccount into a separate session-scoped variable and used by multiple components?


      Thanks.
