Hi Martin,
I'd say AbstractSingleSelectChoice should throw a WicketRuntimeException
when the id is null.
The reporter of the issue should use #setNullValid(true) instead of his
nullItem.

I think Wicket should warn you somehow when the returned idValue is null
though. Because now it sets null as a model object and the client choice is
being lost.
@Sven, @Igor: what do you think ?

When the DropDownChoice try to convert the submitted choice id back to the

there is an iteration over the choices.
You get the NPE in this iteration because nullItem has no id.
Have a look to AbstractSingleSelectChoice's setNullValid(true) method to
include a null value.

Haven't run the code but my guess is that the idValue returns a null

of "0".
Take a look at
AbstractSingleSelectChoice.convertChoiceIdToChoice(String) line
281. (Wicket 6.15.0)
"if(renderer.getIdValue(choice, index).equals(id)"
This would trigger a NPE if a null is returned, which would be the case
with
your "nullItem".
Cheers,
Marco

I'm pretty sure it's my fault, but I can't spot it. I'm trying to use a
DropDownChoice with custom renderer and a PropertyModel, without a Form.
I get a NullPointerException in AbstractSingleSelectChoice, here is the
quickstart:
