Is there an easy way to add/override a function to all my Wicket classes (panels, pages, forms, etc.)? For example, I have a custom session. Rather than having to cast (MySession)getSession() , I just want getSession() to return a MySession. Two solutions come to mind, but neither seems optimal.
First, I could create a MyPanel for all my panels to extend, a MyPage for all my pages to extend, etc. and have MyPanel and MyPage override getSession(). However, that means a lot of duplicated code. Second, I could update the Wicket source code, which would be quick and easy, but then make upgrading Wicket difficult. Is there a simple Java solution that allows me to change/add function definitions into existing inheritance hierarchies?
