[jboss-user] [JBoss Seam] - Missing something basic with regards to bijection

[mlh496]

Hey there,

Suppose you have a Stateful bean called "PersonManager" that handles both the CRUD and search features for the "Person" entity.  I'm using Session scope.  I have the following in the "PersonManager"

  | @DataModel
  | List<Person> people;
  | 
  | @DataModelSelection
  | Person selectedPerson;
  | 
  | // Person property
  | private Person person;
  | public void setPerson(Person person) { this.person = person; }
  | public Person getPerson() { return person; }
  | 
  | public void clickPerson() { 
  |     person = selectedPerson; 
  |     return "edit";
  | }
  | 

When I display a clickable data table with a command link to clickPerson, the selectedPerson does get injected into the PersonManager.  I then assign this to the "person" property.  Now if I go to a page to edit the Person, expressions like #{personManager.person.firstName} fails.  HOWEVER, if I use an expression like #{personManager.selectedPerson.firstName} it works.

Why doesn't it stick when I copy the selectedPerson to the property?

PS: I'm using the edit page to also create new people.  This is why I wanted to bind the edit page to a property and not a selected item.
