Tapestry 5.3 Ajax Exception Reporting

I just put together this screencast about an exciting improvement to how Tapestry 5.3 presents server-side exceptions to the client.

Tapestry is certainly moving further and further into the rich client space; I think there's some compelling features of Tapestry that make splitting the application across the client web browser and the server quite attractive, including a uniform approach to rendering (both traditional page oriented requests, and Ajax partial page renders). In any case, the weak link in the chain used to be that with Ajax requests, server-side exceptions sent you scurrying to look at the console, and you would lose (along the way) a lot of the power of the Tapestry exception report page; now you get to have your cake and eat it too.

The real excitement will be coming in Tapestry 5.4, which will push much deeper into improved JavaScript and Ajax support, including a move to framework agnosticism (as in, switch over to jQuery seamlessly). Part of that support is already in 5.3, with more to come.
