Hello,
I've notices a bug in general in your technologies while opening simultaneously (ie, by ctrl/shift+clicking or middle-clicking quite fast) multiple pages in tabs.
Take for example the home screen of this forum and click on the different forums, like if you were doing the repetitive task of screening the last messages of all forums. You click fast and multiple tabs load at the same time.
You may then notice that the content of the tabs are a bit scrambled : you may have the exact same content, or the heading of one while having the list of a second and the page count of a third.
Clicking a a page count of one tab executes the associated action on one tab, so that I can end up in the "next page" of a different forum from another tab.
I've also tested on http://www.exoplatform.com/company/public/website/, clicking on the "Collaboration", "Social" and "Core Services" links just below the big fading banner. The result is random, but I have noticed among other that I had the same title while having different content (the urls were naturally different).
While typing this message I'm sure that if I click on a link to open it on a tab, it won't accept the submit of the form from the prior page.
The bug does not reproduce everywhere, for instance your xWiki seems to perform well (to be asserted).
By the way, I'm using Chromium 5.0.375.127 (55887) on Kubuntu 10.04.
Cheers and good luck for this/these bug(s) !
