That is a requirement
So you have to give a list of id's or don't set a rollid but a roll property.

Hi wicketeers
I have a "small" problem with DropDownChoice that I have been staring
at for hours...
Now I have a ListView containing two textfields (working fine!) and a
dropdownbox. And this is my problem.
==============================
add (new ListView("partnerListe", partner){
protected void populateItem(final ListItem item) {
final TilknyttetGruppeVO gruppe = (TilknyttetGruppeVO)
item.getModelObject();
item.add (new TextField("personnavn", new
PropertyModel(gruppe, "personnavn")));
item.add (new TextField("email", new PropertyModel(gruppe,
"email")));
item.add (new DropDownChoice("rolle", new
PropertyModel(gruppe, "rolleId"), roller, new ChoiceRenderer("name", "id")));
item.add (new Link("delete") {
public void onClick() {
sag.getTilknyttetGrupper().remove(gruppe);
}
});
}
});
===============================
The roller, which is a list containing POJO from the DB is also given in the
contructor to the dropdownchoice.
======================
private class Rolles implements Serializable {
int id;
String name;
public getter / setter
======================
Now when I submit the Form including the selected value of the dropdownchoice I
get the following error. I seems to me that when DropDownChoice updates its
model it uses toString() instead the setMethod given in the ChoiceRenderer...
