Injecting UI elements from JavaScript might keep the platform code clean, it makes the extension code dirty. Second, IMO if all (bundled) extensions were to do this, you would have a very clumsy page load, especially on low end machines running a (relatively) old browser. You would have a latency of couple of seconds between the time you think the page is loaded and the time you can actually interact with the page. Especially if some of those extensions do perform AJAX requests, like the annotations extension is doing right now. In my opinion this is bad, and as much as possible the DOM sent to the browser should be complete (there is almost no extra cost to do such in comparison with the initial cost of the HTTP request). Right now you don't feel it because only annotations are build this way. Make it 10+ such extensions on IE8 on a not so powerful machine and you will feel it, I'm pretty sure. > > > I'm not talking about external features.

Indeed I don't think it's good to have hooks for external extensions. (my vision is: XE is the product we ship right now, and it's ok to make sacrifices like we did for forgot username/reset password application to make a better product) Jerome. > > Thanks > -Vincent > > > Jerome. > > > > > >> > >> Thanks > >> -Vincent > >> > >>> Jerome > >>> > >>> > >>>> Thanks > >>>> -Vincent > >>>> > >>>>> Guillaume > >>>>> > >>>>>> Thanks > >>>>>>> -Vincent > >>>>>>> > >>>>>>>> > >>>>>>>> I`ve created http://jira.xwiki.org/browse/XWIKI-6991 with some > >>>> details > >>>>>> about > >>>>>>>> what I have done and made a pull request at > >>>>>>>> https://github.com/xwiki/xwiki-platform/pull/24 since I did not > >> want > >>>> to > >>>>>> rush > >>>>>>>> at applying the changes without running them by you guys. > >>>>>>>> > >>>>>>>> I`ve broken the issue down to subtasks with separate commits to > make > >>>> the > >>>>>>>> review easier. > >>>>>>>> > >>>>>>>> There currently is a demo server for the workspaces feature at > >>>>>>>> http://wiki30-demo.xwiki.com but I will have to update it > tomorrow > >>>> with > >>>>>> the > >>>>>>>> latest version.
