Simple @In and @Out

[nur]

Hello all.

I had a xhtml with a list of person and when i click on one person of the list i'm redirected to detail view for this person.
Then I have 2 pages: personList.xhtml and personView.xhtml.
Each page have a backingbean: personListBean.java and personViewBean.java

My link redirection on personList.xhtml look like:

<h:commandLink action="#{personneListBean.selectEntity(_personne)}">
     <h:outputText value="#{_personne.id}" />
</h:commandLink>

In my personneListBean I have:

@Out(required = false)
private Person selectedPerson;

public void selectEntity(Person p) {
     System.out.println("p: " + p.getNom());
     selectedPerson = p;
     System.out.println("selectedPerson: " + selectedPerson.getNom());
}

And when i click on a row i see in console:

11:03:09,876 INFO  [STDOUT] p: Lefebvre
11:03:09,876 INFO  [STDOUT] selectedPerson: Lefebvre

Then i know my code is executed and selectedPersonne is not null.

In personViewBean.java I have:

@In
private Person selectedPerson;

+ getter and setter

But when i click on a row my personView.xhtml fall in error:

Caused by: org.jboss.seam.RequiredException: @In attribute requires non-null value: personneViewBean.selectedPerson

How can i make it's work?

thx

What is the scope of you personViewBean?
Try Conversation,
try add @Begin to setter method, or even create another method for initialization not to intercept with setters that will be called on xhtml page.

And don't forget to end conversation.

Thx for your answer.

The scope was Page but it's the same with Conversation.

I have add @Begin and @End but yet same problem..

All personViewBean code:pastebin

I don't see what you want want say with

even create another method for initialization not to intercept with setters that will be called on xhtml page.

When i use

@In(create = true)

I don't have any error my it's open new Person, not the selected in table

Ok it's work now.

I change the name of the variable @In and @Out selectedPerson by the name on the @name on entity Person

And change the scope of personListBean to conversation
