public abstract class SongList
extends org.apache.tapestry.BaseComponent

The component to show a list of Songs. Song-lists are very verbose. Because Hibernate loads everything lazily, it can very well be that we generate an OutOfMemoryException, while traversing through the SongList, initializing lazy-properties on our way. Because of that, this component throws objects away after rendering them. Note that this prevents OOME on huge lists, but penalizes the rendering of lists as well, because sometimes objects have to be fetched from the DB (or hopefully a 2nd-level cache) more than once.
