Thanks. I'll check it out after I finish playing golf. :) I have another associated question.
If there aren't any Pricing objects for a given Track, I want to put a message in the page like "You don't have pricing setup yet." The problem is that if I put that span tag in the markup: <span wicket:id="noPricingMessage">Test</span> And don't add the object to the page, Wicket will throw an exception. Will calling setVisible(false) get me around this?
