annotation is commented out is a little disconcerting.
The pid attribute will not be set unless you uncomment the @RequestParameter
annotation (which will directly inject the value) or add an entry in your
pages.xml which will call your set method such as,
| <pages>
| <page view-id="/person.xhtml">
| <param name="pid" value="#{manager.id}"/>
| </page>
| ...
| </pages>
I also do not see where fan is being outjected to the page so I don't know
where your id would be coming from. Are you providing a list of persons and
then the user can edit a person from the list? If you are looking to achieve a
RESTful URL here (which is the only reason I could think of for doing it this
way), an easier way to accomplish this would be...
@Stateful
| @Name("manager")
| public class ManagerAction implements Manager {
|
| @RequestParameter
| Long pid;
|
| @In (required=false) @Out (required=false)
| private Person person;
|
| @DataModel
| private List <Person> fans;
|
| @Factory(value="person")
| public void loadPerson(Long pid) {
| if (pid != null) {
| person = (Person) em.find(Person.class, pid);
| } else {
| person = new Person ();
| }
| }
| ...
|
Also note that you will not be in the same conversation when the Person is
loaded because you are using a general link <a href ...>. Any conversation
state will not be propagated. Hope that helps.
