I have created http://jira.xwiki.org/jira/browse/XWS-107. Now I wish I can reproduce it on a local instance to be able to properly debug, as I still do not know the exact reason. (I just understand it's a NPE when comparing two Documents with 'equals'). Any cases, XWS 1.1M2 will provide a fix for it. Regards, Jerome. > > Jerome. > >> >> Where I can find XWS.MySpaces?
