Hi,
I have a strange problem with the PropertyModel and a form. The property
model is bound with one of my class, like that:
shops = new DropDownChoice("shop", new PropertyModel(formTarget,
"shops"), new ShopDAO().findAll(), new ChoiceRenderer() {
@Override
public Object getDisplayValue(Object o) {
if (o instanceof Shop) {
Shop s = (Shop) o;
return s.getName() + " (" + s.getUrl() + ")";
}
return null;
}
});
My "formTarget" has setShop and getShop methods.
I have in this form an "edit(MyClass)" method, for editing an existing
record. It looks like this:
public void edit(MyClass l) {
[...]
shops.modelChanging();
formTarget.setShops(l.getShops());
shops.modelChanged();
[...]
And when I test it, sometimes it works fine (the drop down choice selects
the right item), and sometimes not (it selects the "null" value). I played a
little with it, and about half time there is no problem and half time the
"null" value is selected... (and I'm certain the property isn't null)
Is is a known issue? How can I fix it?
Thank you very much ;)
