[jboss-user] [JBoss Seam] - Question On @Datamodel Outjection
Hello,
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
