I have a suite of tests that works very well on a web application using jQuery 1.7. This week jQuery was updated from 1.7 to 1.8.1. Now it seems nothing works. Using 1.7 there was no need for waits() all over the place, it seemed to synchronize great with the ajax. With 1.8.1 I need waits, and on many pages it seems unable to catch the redirect. HtmlUnit even sends the right requests, but it just doesn't seem to update the page itself with the responses (even though looking at all responses, it does recieve them).
