I have the same use case only a lot more complicated (nested list views in
different panels).
The easier way to auto-select or auto-deselect (aka change the model
object) is to share a CompoundPropertyModel across your component
hierarchy. In this way a single component can interact with its model
object and have access to everything on the page. Then it becomes a matter
of adding the component you want to refresh to the AjaxRequestTarget.
