I have no idea what your problem is, but it is probably not related.
The only way I know of to debug this is:
(a) get a good grasp of how the Ajax page cache works
(b) log out all the requests (and probably response content) and
examine them carefully to see what went wrong

yeah, good point -- i think we have a safety net of 2 requests,
but i seem to recall that if you can manage to trigger 3 requests
for an update container before the first one comes back, you can
get this to happen, except that wo blocks by session, which makes
this pretty hard to actually pull off. not sure how you'd actually
do it.
If I have time, I will dig into it when it happens again. I recall
that the context ID was waaaaay off when this happened.

I've gotten them with Selenium tests were it was triggering
actions faster than a user could. I did not look into it, but
expect that things may have been happening out of order. Adding
a 250ms or 500ms pause here and there fixed it.

You're the second person who has mentioned backtrack errors with
new Ajax. Did something break? You should never get a backtrack
error from an Ajax request.

Hello all.
In my app I have so AjaxUpdateContainers which gets updated
when pressing some AjaxSubmitButtons , (funny, :) ), now
sometimes, when I, clicking the submit butons, I get the you
backtrack too far exception, it happens randlmly, it can happen
after clicking 10 times the button, or after clicking 5, or
sometimes it doesn't even happen.
this is what Im doing at the end of the WOActionResult methods,
if (this.didBacktrack()){
session().defaultEditingContext().revert();
// handle and prepare to report errors
// this.errors.addObject("Unable to process page after back
button was pressed.");
return this.context().page();
}
I read it somewhere in the wiki, but it seems its not working..
Any suggestions.?
thanks
Gustavo
