Wicket 1.5 Wizard and AjaxFormComponentUpdatingBehavior for a
DropDownChoice
I have an application in wicket 1.4 with a wizard. Inside a WizardStep I have
a simple DropDownChoice with an AjaxFormComponentUpdatingBehavior where
inside onUpdate method i get the model object
protected void onUpdate(AjaxRequestTarget target) {
String type = choice.getModelObject();
...
}
This works well.
But migrating to 1.5.5 makes this not working. The method is entered but the
model is always null.

This markup is OK.
I guess you put it in a repeater and that's why you end up with
several <select>s with the same id. And later when submitting just the
first sends its value.
Just remove the 'id' attribute. Wicket will create a unique one for
you automatically.
Provide 'id' only when you want to avoid using
Component.setMarkupId("somethingStable") in .java

The problem was also the id inside html components. When we have both
wicket:id and id, in 1.5.5 id is not overwritten and no events are triggered
for that component.
I wonder why this was not put inside the migration guide to 1.5.
Could be possible to get some warning in case we have something like this:
<label wicket:id="type" for="choice">[]</label>
<select wicket:id="choice" name="choice" id="choice"/>
and tell user that it's choice component in this case would not receive any
events?
