Hi,
I have no clue whether this is your problem but one thing is noticeable:
@ManyToOne needs a @JoinColumn

Hi,
I'm learning Tapestry 5, and I would like to know how
to do the following simple example :
I have an object called Person and an object called
Group.
Person(id, name, group_id)
Group(id, name)
I would like to create a simple CRUD application. I'm
following T5 tutorial (using beaneditform) to have a
page where I can create/insert a Person in my
database.
It works as long as I haven't relation :
@Entity
public class Person {
@Id
private Integer id;
private String name;
/* GETTERS AND SETTERS */
...
}
But when I add the relation :
@Entity
public class Person {
@Id
private Integer id;
private String name;
@ManyToOne( cascade = {CascadeType.PERSIST,
CascadeType.MERGE} )
private Group group;
/* GETTERS AND SETTERS */
...
}
There is no field in the beaneditform to set the
group. I understand there is no universal behavior,
and I think customization is required.
I would like to customize my form to add a new text
field where I can input the group_id. How can I do
this?
Thanks
Julien
