Question On @Datamodel Outjection
hasc May 21, 2007 3:58 AMHello,
i have a problem outjecting a datamodel.
i have a class the holds the business logic for a calculation process. It holds the Entity Calculation.class where the data is stored. during the calculation i create another object that holds the response information.
@Stateful @Scope(ScopeType.CONVERSATION) @Name("scmanager") public class CalculationManagerBean implements CalculationManager{ @In(create=true) ExpressCalculator expresscalculator; @Out(scope=ScopeType.CONVERSATION,required=false) BudgetOverview budgetOverview; ... @Create public void init(){ log.debug("initialize new calculation entity"); calculation = new Calculation(user); return; } /*** business logic ***/ public void executeExpressCalculation(){ budgetOverview = expresscalculator.calculate(calculation); } ... }
@Stateless @Name("expresscalculator") public class ExpressCalculatorBean implements ExpressCalculator { public BudgetOverview calculate(Calculation calculation) { // initialise BudgetOverview BudgetOverview budgetOverview = new BudgetOverview(); //some code // this is the datamodel Set<CostItem> costItems = calculateInstallationCosts(); budgetOverview.setCostItems(costItems); return budgetOverview; } // some functions }
and here is the class BudgetOverview
@Name("budgetOverview") @Scope(ScopeType.CONVERSATION) public class BudgetOverview{ // some attributes // the datamodel @Datamodel public Set<CostItem> costitems; // getter and setter methods }
So the problem is:
In the view I can display all attributes from the budgetOverview except the datamodel selectitems. But i can e.g. display the size of the datamodel. So it is set properly just not outjected.
If i change the code and outject the datamodel in the CalculationManager class and initialize it via a getter method from the BudgetOberview it works fine.
I have no clue if i made a mistake or the overall concept of outjecting an object that outjects a datamodel doesnt work.
Help would be great. and i hope you could follow this explanation.
thanks,
hasc
