One of my favorite blog authors gives us the second installment of his award winning series of Wicket articles (I have your awards right here, Nathan!): Reducing and re-using code. This time Nathan discusses Wicket's abilities to create reusable components using panels, markup inheritance. In the article he creates an extravaganza of calculators on a single page. Geeky yet somehow comforting.
In case you missed it, the first installment was an introduction to the Wicket framework, which is also a very good read.
