XPages Extension Library
When you try to expand/collapse an outline (xpageext.net, oneui, outline zone) you get a JS Error : XSP.oneUIMenuSwap is not a function
This is a regression that will be fixed in the next build.
By the meantime, you can manually add the "extlib.dijit.OneUINavigator" dojo module to your page, and eventually the dojofx "dojo.fx" if you use ui effects.
