Wiki MarkupHere the page (or indeed anything derived from a Wicket {{Component}}) will have its dependencies injected when created. _\[Constructor/superclass chaining down to the Component(final String id, final IModel model) constructor, where there's a call to getApplication().notifyComponentInstantiationListeners(this);\]_

When doing this it is important to remember not to initialize dependencies, to null or any other value, e.g.private ContactDao dao=null;. Don't do this because the injector will run before the subclass initializes its fields, and so the dao=null will override the created proxy with null.
