How to manage two instances in Home component?

[ovistanciu]

Hello.

I have a problem. Let's say I have 2 Entities : Child and Parent. Every child has 2 parents, that is in Child there are 2 fields:

@Entity
public class Child{

       private Parent mom;
       private Parent dad;
}

And Parent has a gender:

@Entity
public class Parent{
      private int gender; //1 or 2
}

Also, I have a ChildHome and a ParentHome. My question: on the ChildEdit (ChildHome component) page, how do I select 2 different(one of each gender) instances of Parent for the Child?
Do I need to have 2 instances of ParentHome in ChildHome?

Thank you for your time.

I think you wanna read section 3.2.9 in the seam reference.  If I follow you correctly you are wanting to annotate Parent with the roles of mom and dad. Though I have not used that with entities specifically, I have just used this in the context of session beans.

e.g.

@Roles(
   {@Role(name="mom", scope=SESSION), 
    @Role(name="dad", scope=SESSION)})
