try adding AjaxFormComponentUpdatingBehavior to your drop down
some thing like this
AjaxFormComponentUpdatingBehavior updateBehavior = new
AjaxFormComponentUpdatingBehavior("onchange")
{
private static final long serialVersionUID = 1L;
protected void onUpdate(AjaxRequestTarget target)
{
target.addComponent(container);
}
};
yourDropDown.add(updateBehavior);
so during the onChange the model object will get updated and you can access
the value by calling the getter
don't know if this is the best way though
