Re: [Wonder-disc] Session Timed Out with AjaxTree

I can't believe you are going to make me say it. It seems that for some reason, the guy who's code I "borrowed" is using sessions in a unique way. (I'm not entirely sure how or why) Anyway, when I asked him if he had any idea why his code worked and mine didn't he suggested that perhaps he was pulling the session out from under me in his original code. With this fresh perspective, I suddenly saw that he had overridden sleep() in the WOComponent that I was using and was calling session.terminate() So the reason my session timed out almost right away was because I was killing it every time the page loaded. Now do you understand my shame? If my boss asks what I was doing all day, it was a learning exercise to understand the request-response flow of a Project Wonder Ajax App. Jeremy On Oct 28, 2008, at 3:51 PM, Chuck Hill wrote: > But but but what was wrong?
