urgent beginner question

[mpelaez]

Hi, I have one question, i hope someone help me

Take a look to this example

@Name(a)
@Scope(ScopeType.CONVERSATION)
class A{
 
  private Father obj;

  @In
  private B b;
 
  public void M(){
    b.getSon().setFather(this.obj);
    b.setName(Eduard);
  }

 
}

@Name(b)
class B{

    private Son son;
   
}

the problem is that when I call the method M() works fine but if after I call  b.son appears null.
Any idea??

@Name("a") 
@Scope(ScopeType.CONVERSATION) 
class A{
     private Father obj;
     @In private B b; 

     public void M(){ 
         b.getSon().setFather(this.obj); b.setName("Eduard"); 
     }

}

@Name("b") 
class B{
     private Son son; 
}

what do you mean exactly by if after I call b.son?

[mpelaez]

I mean if I have another method in class B that called oject son, for example:

boolean M(){
if(this.son.getName().Equals(Eduard))
   return true;
return false;
}

when I call this method from presentation the object son is null even when It was created in class A.

You can try to outject like this:

@In @Out private B b;

make sure you outject to the same context (SFSBs are conversation-scoped by default but JavaBeans are event-scoped).

Then that instance will be available in another Seam component.

[asookazian]

or you can provide a getB() method in class A and inject A into B.

ok, thanks. I am going to tried that.
should I put to JavaBeans conversation scope??
B b is a ssesion bean but the object son inside b is an entity bean

I do not realy like doing of that way, I prefer tried the outjection. Thanks a lot for you help and sorry for the bad english.
