Hello! I have installed xwiki on an Oracle Application Server and Oracle 10g Database. I have problems when I create new groups. I don't get an error in the webbrowser, everything works as normal except that my groups doesn't show up. After I typed the new group name and pressed OK, I return to the list of groups but still only got the XWikiAllGroup. In the log I get this (it is a longer message but I don't want to make a long posting): org.hibernate.ObjectNotFoundException: No row with the given identifier exists: [com.xpn.xwiki.doc.XWikiDocument#1287555159] at org.hibernate.impl.SessionFactoryImpl$1.handleEntityNotFound(SessionFactoryImpl.java:377) at org.hibernate.event.def.DefaultLoadEventListener.load(DefaultLoadEventListener.java:145) I get the new group in the database (taken from XWIKIOBJECTS; however I don't know the map of the schema you use, so I might be looking on the wrong place): "XWO_ID" "XWO_NUMBER" "XWO_NAME" "XWO_CLASSNAME" "1300917321" "0" "XWiki.NewGroup" "XWiki.TagClass" Does anyone have a clue what the solution to the problem is? Btw I can create users... Thanks alot Anders Andersson
