>                 Key: JBSEAM-3903
>                 URL: https://jira.jboss.org/jira/browse/JBSEAM-3903
>             Project: Seam
>          Issue Type: Feature Request
>    Affects Versions: 2.1.0.SP1
>            Reporter: Francisco Jose Peredo Noguez
>
> Lets say you have 2 classes:
> class Parent{
>     private Long id; private Integer version; private String name;
>     private Set <Child> children;
> }
> and
> class Child{
>     private Long id;private Integer version; private String name;    
>     private Parent parent;
> }
> with a typical one to many / many to one relationship (Parent.children.Child/Child.parent.Parent)
> So you want them to become @Entities and add the required @Annotations. Then you run seam-gen on them, and run you generated application:
>    1. You click the Parent List menu option.
>    2. You are presented with the page ParentList.seam that allows you search parents, or to create a new one.
>    3. You click the Create parent button.
>    4. You write a name for the parent: "Peter".
>    5. You click "Save".
>    6. You are presented with the page Parent.seam, that displays you newly persisted entity in a "read-only way"
>    7. You click "Done"
> so far so good... but then
>    1. You click the Child List menu option.
>    2. You are presented with the page ChildList.seam that allows you search children, or to create a new one
>    3. You click the Create child button.
>    4. You are presented with the page ChildEdit.seam.
>    5. You write a name for your new Child entity: "John"
>    6. You decide that you want connect this new Child entity with a parent entity, and then you click "Select parent".
>    7. You are presented again with ParentList.seam that allows you to "select" a parent.
>    8. So, you select "Peter" by clicking in the "Select" link
>    9. And you return to ChildEdit.seam, but the value for the name property of the Child is now LOST.
> I think seam-gen should be able to do this correctly (without losing the values in ChildEdit.seam).
