I think another way to do it is to call setModelObject() with the appropriate parameter on each component that needs to be updated. I chose to use the modelChanged() approach, however, because I'm using the presentation model pattern (http://martinfowler.com/eaaDev/PresentationModel.html) that populates the model properties behind the scenes. At least in my experience, I had to call modelChanged() to reflect the new values.
By the way, so far, the presentation model pattern seems to work nicely with Wicket. This includes using the LoadableDetachableModel to call the presentation model to get data to populate a ListView and dereference the data for memory conservation. The result is less verbose Wicket code and the option to use the presentation model in other web frameworks. Only time will tell if this approach will scale with Wicket.
