You are debugging an MAF application. The application stores the total cost of items in the user’s shopping cart in a managed bean variable. The total cost is then displayed in an AMX page via anamx:outputTextcomponent. A button is pressed on the pageto add another item to the shopping cart, and, as a result, the total cost value is changed in the managed bean. However, you notice that the value is not changed in the AMX page.

Which is the reason for this behavior?

  1. The total cost variable does not have aPropertyChangeListenerfiring on data change.

  2. The scope of themanaged bean ispageFlowScope.

  3. The variable is anintinstead of adouble.

  4. Theamx:outputText partialTriggerproperty must include the ID of

theamx:commandButtonthat is invoking the change.
