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.
| @(protected)
| @(protected)(ScopeType.CONVERSATION)
| @(protected)("manager")
| public class CalculationManagerBean implements CalculationManager {
|
| @(protected) 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.
| @(protected)("listmanager")
| @(protected)(ScopeType.PAGE)
| public class ListManager implements Serializable{
|
| @(protected)
| Calculation calculation;
|
| @(protected)
| 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.
regards,hasc
