Getting this since beta3 as well, and not because im idle on the site
I dont think so i got this error from day one on beta 2 and beta 3 on my demo site and i still get it on my live site running beta three. It happens on almost any click that changes a page.You have a few add-ons installed don't you?
It's possible it could be related to one of those as I've never had that particular error here.
Mike, is there something that we have to do to our installs or will it be implemented in the next version?This was caused by a change in jQuery. I had actually stumbled upon it elsewhere (cache rebuilding) and worked around the behavior there, but I didn't realize it happened elsewhere. Fixed now.
All fixes Mike and Kier post about will be implemented in the next version.Mike, is there something that we have to do to our installs or will it be implemented in the next version?
