Excellent, that's perfect. The part I was unsure about was what to
pass for the arguement for getObject()....
Thanks Matej!

Suppose you have
IModel model = new LoadableDetachableModel() { ...
you can get the model any time:
List<Item> myItems = (List<Item>) model.getObject(null).
First time you call getObject the model is attached (list is loaded).
Until it's detached, getObject(null) will always return the loaded list.
