Hi, I tried to upgrade xwiki enterprise from version 1.2 rc3 to 1.8.2 and it was by no means an easy task. The good thing is xwiki is very robust and I managed to recover most of it except the wiki preference. I would appreciate if someone could help me get the last piece going. Note: I have imported xwiki Application Adminstration xar. And when i select the Panel Wizard icon, i get the following messages from the console [WARNING] Deprecated usage of method [com.xpn.xwiki.api.XWiki.getHashMap] in XWiki.XWikiPreferences@21,28 [WARNING] Deprecated usage of method [com.xpn.xwiki.api.XWiki.getArrayList] in XWiki.XWikiPreferences@23,39 [WARNING] Deprecated usage of getter [com.xpn.xwiki.api.XWiki.getHashMap] in XWiki.XWikiPreferences@54,29 [WARNING] Deprecated usage of getter [com.xpn.xwiki.api.XWiki.getHashMap] in XWiki.XWikiPreferences@55,8 [WARNING] Deprecated usage of method [com.xpn.xwiki.api.XWiki.getURLEncoded] in XWiki.XWikiPreferences@114,120 [WARNING] Deprecated usage of getter [com.xpn.xwiki.api.Document.getWeb] in XWiki.XWikiPreferences@6,16 [ERROR] Introspection Error : Ambiguous method invocation print(null) for class class org.joda.time.format.DateTimeFormatter [WARNING] Deprecated usage of getter [com.xpn.xwiki.api.Document.getWeb] in XWiki.XWikiPreferences@12,11 [WARNING] Deprecated usage of method [com.xpn.xwiki.api.XWiki.getRecentActions] in XWiki.XWikiPreferences@5,31 [WARNING] Deprecated usage of getter [com.xpn.xwiki.api.Document.getWeb] in VMProxyArg : Reference@1,15 [WARNING] Deprecated usage of getter [com.xpn.xwiki.api.Document.getWeb] in XWiki.XWikiPreferences@1,6 [WARNING] Deprecated usage of getter [com.xpn.xwiki.api.Document.getWeb] in XWiki.XWikiPreferences@3,10 [WARNING] Deprecated usage of getter [com.xpn.xwiki.api.Document.getWeb] in XWiki.XWikiPreferences@10,20 Any help would be greatly appreciated Thanks in advance chung-onn
