An interesting Spring Framework quirk
Recently, I discovered the joy of the PropertyEditorRegistrar interface in the Springframework, for conveniently registering property editors to bind between objects and text when rendering forms. This joy led me to discover an interesting quirk : if you subclass a Form Controller and register property editors that way, the object of a field will be bound to the BindStatus.value property, but if you use a PropertyEditorRegistrar, that value gets edited and the spring representation of it bound to BindStatus.value. This is a small distinction that makes a huge difference when writing (and rendering) your pages.
