this code has the same problem

<form action="/">
        <div><select wicket:id="jobTypeFilter">
                <option>JobX</option>
                <option>JobY</option>
        </select></div>
</form>

add(jobTypeFilter = new DropDownChoice("jobTypeFilter", new HibernateObjectModel(), jobTypeListModel));
jobTypeFilter.add(new AjaxFormComponentUpdatingBehavior("onChange") {
	@Override
	protected void onUpdate(AjaxRequestTarget target) {
		target.addComponent(jobsWrap);
	}
});

>             Project: Wicket
>          Issue Type: Bug
>          Components: wicket
>    Affects Versions: 1.3.0-beta2
>            Reporter: Pekka Enberg
>
> Chaning a value in DropDownChoice causes the following Javascript error:
> e has no properties
> http://localhost:8080/paivi/app/resources/org.apache.wicket.ajax.AbstractDefaultAjaxBehavior/wicket-ajax.js
> Line 322
> Which is why OnChangeAjaxBehavior.onUpdate() is no longer triggered. This stopped working after we got a new snapshot from http://wicketstuff.org/maven/repository/. The changeset that broke it is probably the one for WICKET-394 but I have not confirmed this.
