If you use objects without overriden #equals() and #hashcode() and
DropDownChoice you have several options:
1) use a custom ChoiceRenderer
2) override AbstractSingleSelectChoice#getModelValue()
3) make sure the selected choice is the identical object contained in
the choices list (e.g. via OpenSessionInView)
https://issues.apache.org/jira/browse/WICKET-4353 might give you more
information.
Best regards

Hello *,
I have a FormComponentPanel derived class that uses a DropDownChoice with a
ChoiceRenderer. The DropDownChoice id matches the field name in my model
class
and I use a CompountPropertyModel wrapping my model instance for the
component.
Code snippets:
class StreetAddress
...
private String address;
@ManyToOne
private District idDistrict;
... usual getters and setters
class StreetAddressFormCP extends FormComponentPanel<StreetAddress>
...
super(myCompountPropertyModel));
add(new TextField("address"));
add(new DropDownChoice("idDistrict", ...));
class StreetAddressForm extends Form<StreetAddress>
...
super(myCompoundPropertyModel);
add(new StreetAddressFormCP(myCompoundPropertyModel));
...
All seems to work except that when I edit an address and change district in
the dropdown, my onSubmit receives a model with the old value for
idDistrict
(but new edited value for address), so that part of the edit is lost.
Isn't DropDownChoice supposed to always update the model when the user
selects
an item/submits the form?
P.S. onSubmit overridden on a Button behaves like stated above, while
onSubmit
overridden on the Form behaves differently: it receives a model with a null
target...
