T - Model object typepublic abstract class AbstractPageableView<T> extends RefreshingView<T> implements IPageableItems
The view is populated by overriding the getItemModels(int offset, int count) method
and providing an iterator that returns models for items in the current page. The
AbstractPageableView builds the items that will be rendered by looping over the models and
calling the newItem(String id, int index, IModel model) to generate the child item
container followed by populateItem(Component item) to let the user populate the
newly created item container with with custom components.

NOTE: If you override this, you *must* call super.onBeforeRender() within
your implementation.
Because this method is responsible for cascading Component.onBeforeRender() call to its
children it is strongly recommended that super call is made at the end of the override.
