Hi, In the new xwiki architecture we need to take a call for passing the request, response and session around (what is currently called the XWikiContext). We have 2 solutions: 1) we pass it around for all method calls as it's currently done 2) we use ThreadLocal(s). If you don't know what it is see for ex: http://crazybob.org/2006/07/hard-core-java-threadlocal.html .
The advantage of solution 2) is that any component in the new architecture can decide to have the Container component injected (see http://svn.xwiki.org/svnroot/xwiki/xwiki-platform/core/trunk/xwiki-containers/) and thus be allowed to access the request, response and session objects without having all its method add a Container object passed to it. The downside of solution 2) is simply that we associate Unit Of Work with Threads. But since we use a Servlet model and since I don't see any foreseeable future where we would want to use several threads for the same unit of work, I don't think this is limitating for us. See http://blog.objectmentor.com/articles/2007/09/04/thread-local-a-convenient-abomination for some explanation on this. So right now and even though ThreadLocal sound a little bit "hackish", I think this is still my preference as it'll save us from having to pass Container objects everywhere. Since this is an important architecture decision I wanted to have a vote for it.
