Hi all, After updating to XWiki 1.2 I'm trying to get the updated documents included in xwiki-enterprise-wiki-1.2.xar.zip in the installation. If I import all the documents included in xwiki-enterprise-wiki-1.2.xar.zip I systematically get the same three errors with: Main.LuceneSearch Panels.SyntaxHelp Photos.NewAlbum Only by previously removing these three documents I get a full import. These are the ERROR messages recorded in catalina.out: sh-3.2# tail -n2000 catalina.out | grep ERROR 11:52:16,486 ERROR http-80-15 http://xcontroller.xen.net/xwiki/bin/import/XWiki/Import?editor=import&… SimpleLog4JLogSystem:logVelocityMessage:154 - Left side ($request.withversions) of '==' operation has null value.

Something that could/must be improved in the .xar file? Let me know if more lines from catalina.out or any other test can help to work out this issue. Thanks.
