seam-gen not generating pages to @ManyToMany relationships

[tognado]

why doesn't seam-gen (seam generate-ui) create automagically session beans and xhtml pages to ManyToMany relationships ?

I have an entity boy that contains a Set of toy entities. It seems that seam generate-ui created the mysql database correctly, Boy and Toy pages and sessions, but didn't create a page where I can associate boy to toys at all. Is that a miss use or seam does not provide this ? If seam does not provide, can anyone help me doing this ?

ps: I am using jboss 4.2.3.ga, jboss 2.1.1-ga, jdk 1.5, ant 1.7, eclipse jee 3.4 and jboss tools (development version) in my debian box.

Below you can read my very simple souce-code:

BOY.JAVA

@Entity
public class Boy implements java.io.Serializable{

    private static final long serialVersionUID = 1L;
    private Long id;
    private String name;
    private Set<Toy> toys;

    @Id @GeneratedValue
    public Long getId() {
        return id;
    }
    public void setId(Long id) {
        this.id = id;
    }

    @NotNull
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }

    @ManyToMany(cascade = CascadeType.PERSIST)
    public Set<Toy> getToys() {
        return toys;
    }
    public void setToys(Set<Toy> toys) {
        this.toys = toys;
    }

}

TOY.JAVA

@Entity
public class Toy implements java.io.Serializable{

    private static final long serialVersionUID = 1L;
    private Long id;
    private String name;

    @Id @GeneratedValue
    public Long getId() {
        return id;
    }
    public void setId(Long id) {
        this.id = id;
    }

    @NotNull
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
}

For it to work correctly, you need to have a reference to Boy in Toy class.  Also, is it creating pages to manage both entities separately; or are they skipped all together?  Any difference in the seam-gen if you change the cascade type to ALL?

I tried both ways and everything almost works, with an exception described below.

Also, is it creating pages to manage both entities separately; or are they skipped all together?

Seam is creating separated pages for managing both entities, but, as i said, boy contains a set of toys and in the boy page there is no toy items to select or something like that. In the boy management, there is just a name field to fill instead of name and toys

Any difference in the seam-gen if you change the cascade type to ALL?

Apparently not :-(

Hi,

i encounter the same problem. I habe many ManyToMany relationships. Could you solve this issue?

[tognado]

Hello, unfortunately i did not. I could not find any AUTOMATED way of doing this using code-gen, so I did it manually.

Hi, can u provide the way you make manually, i have the same problem with many-to-manny relationships
