Hello! I wonder if you could help me out a little. I have just reinstalled Xwiki (emptied the tablespace), undeployed the old one and installed xwiki-enterprise-1.3.2 as a standalone war file. I did it by deploying it to the application server. The system runs Oracle Application Server and Oracle Database 10g. I can login (right now I have superadmin enabled), but when I try to create an account, nothing happens. When I check the logs I get: com.xpn.xwiki.XWikiException: Error number 8002 in 8: Cannot create user XWiki.KaninHare Wrapped Exception: Error number 3201 in 3: Exception while saving document XWiki.KaninHare Wrapped Exception: Error number 3212 in 3: Exception while saving property groups of object XWiki.KaninHare Wrapped Exception: dereferenced: baseproper0_.id.id [select prop.name from com.xpn.xwiki.objects.BaseProperty as prop where prop.id.id = :id and prop.id.name= :name] 08/05/05 11:06:41 at com.xpn.xwiki.XWiki.createUser(XWiki.java:3156) 08/05/05 11:06:41 at com.xpn.xwiki.XWiki.createUser(XWiki.java:2919) ...

I think it is related to any modification. When I try to modify a page I get: Error number 3201 in 3: Exception while saving document Main.WebHome Wrapped Exception: Error number 3212 in 3: Exception while saving property tags of object Main.WebHome Wrapped Exception: dereferenced: baseproper0_.id.id [select prop.name from com.xpn.xwiki.objects.BaseProperty as prop where prop.id.id = :id and prop.id.name= :name] com.xpn.xwiki.XWikiException: Error number 3201 in 3: Exception while saving document Main.WebHome Wrapped Exception: Error number 3212 in 3: Exception while saving property tags of object Main.WebHome Wrapped Exception: dereferenced: baseproper0_.id.id [select prop.name from com.xpn.xwiki.objects.BaseProperty as prop where prop.id.id = :id and prop.id.name= :name] at com.xpn.xwiki.store.XWikiHibernateStore.saveXWikiDoc(XWikiHibernateStore.java:457) at com.xpn.xwiki.store.XWikiCacheStore.saveXWikiDoc(XWikiCacheStore.java:97) ...

Thanks for any help I get. PS: To get everything working I had to add to hibernate.cfg.xml: <property name="hibernate.query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</property> Anders Andersson
