Hi Paul,
The reason for the dropdown over the checkbox is I'm attempting to enforce a
selection. I.e. make required or @NotNull
I think I got a bit carried away by attempting to extend DropDownChoice. Thanks
for the link. The following is what I'm going forward with:
new DropDownChoice<Boolean>("active", new PropertyModel<Boolean>(getModel(),
"active"), Arrays.asList(null, new Boolean(true), new Boolean(false)));
I'll will likely add a IRenderer as well so the choices render as Yes, No, or
---.
Thanks again,
Sean Lawrence

Even better, why are you using a drop down at all? Check boxes are
normally used for true-false choices.

Instead of going to the extent of overriding a class because your model
value is not updated, why not fix the problem?
Take a look at the component reference wicket-example project:
http://www.wicket-library.com/wicket-examples/compref/
More precisely at the DropDownChoice:

Hi,
I'm trying to create a custom form component that extends a
DropDownChoice<Boolean>. The reason I'm doing this is because I need a
form
component that forces a user to select a choice. However, I'm unable to
get
the model to update. What am I not overriding properly? I'm all ears for
suggestions if there is a better way to do this as well.
/**
* A Boolean form component that uses a drop down choice so that
* a user is forced to choose between "Yes" or "No".
*
*/
public class YesNoDropDownChoice extends DropDownChoice<Boolean> {
private static final long serialVersionUID = 1L;
public YesNoDropDownChoice(String id, IModel<Boolean> model) {
super(id, model, Arrays.asList(
Choice.YES.getBoolean(),
Choice.NO.getBoolean()));
onModelChanged();
}
@Override
protected void onModelChanged() {
super.onModelChanged();
setModelObject(getModelObject());
}
/**
* {@inheritDoc}
*/
@Override
protected void convertInput() {
Boolean b = getModelObject();
setConvertedInput(b);
}
}
Thanks in advance,
Sean Lawrence
