Description

I posted on nabble about this here:
http://apache-wicket.1842946.n4.nabble.com/wantsOnSelectionChangedNotifications-RadioGroup-Radio-vs-DropDownChoice-td4665927.html

Essentially on an unmounted bookmarkable page (one that you access directly through: wicket/bookmarkable/package.name.ClassName)
the DropDownChoice#wantsOnSelectionChangedNotifications(T) does not seem to be called.

Having looked at the internals a bit, it seems that the onchange handler is not setting a variable that resolves properly to any ListenerInterfaceRequestHandler
e.g.:
the onchange is:

document.getElementById('form6_hf_0').value='../../page?2-1.IOnChangeListener-form-vegetable';document.getElementById('form6').submit();

but should be something like:
document.getElementById('form6_hf_0').value='./wicket_issue_4.FormPage?2-1.IOnChangeListener-form-vegetable';document.getElementById('form6').submit();

That's just my initial thought, I'm no expert.
