I have solved the issue, I think I understand what was going wrong.
- Tapestry first draws action links as hrefs which cause a page reload for
graceful degredation
- Tapestry javascript magic then goes over all ajax action links and changes
them to javascript method calls
- I had a javascript error which stopped the tapestry javascript magic from
hapening, thus I was seeing the graceful degredation, thus no XHR's
Cheers,
Lance.
