Hi, I have XWiki 0.9.840 running in a local intranet and have a big problem with some documents. These documents contain several objects with a specific set of properties. One of the property is a DBStringListClass. For a few days I changed the behaviour from single to multiple selection. After that everything seems fine until I restarted xwiki. Now some of the documents throw the following exceptions: Error number 4001 in 4: Error while parsing velocity page Wrapped Exception: Invocation of method 'parseContent' in class com.xpn.xwiki.api.XWiki threw exception class java.lang.NullPointerException : null Error number 3202 in 3: Exception while reading document LFS.FontconfigInstall Wrapped Exception: Error number 3212 in 3: Exception while loading object LFS.FontconfigInstall Wrapped Exception: Error number 3212 in 3: Exception while saving property component of object LFS.FontconfigInstall Wrapped Exception: No row with the given identifier exists: [com.xpn.xwiki.objects.DBStringListProperty# The page isn't displayed. For this I cannot repair the documents. As I understand it right the problem is an incorrect relation between a specific set of datas for the object on the document. Is it possible to get the documents back to work? Bye Frank -- Dipl. Inform. Frank Häfemeier <[email protected]> ----------------------------------------------------
