      It's possible to debug this error and in this case there's nothing wrong in Wicket. However, Wicket can help making the debugging much easier by wrapping the Exception and mentioning the component's path, which will allow us to pointpoint the problematic model rather quickly.

      In a page with tens or hundreds of (nested) components, without this info it will take some time.

      I'm pretty sure you'll approve this request. Thank you Wicket Thank you mgrigorov
