Hi, i've succeed to purge History of a single document using velocity: $xwiki.getDocument('XWiki.123123').getDocument().resetArchive($context.context) There's a problem in trying to purge history of more than one/two documents: #set($sql = ", BaseObject as obj where obj.name=doc.fullName and obj.className=’XWiki.XWikiUsers’") #set($allUsers = $xwiki.searchDocuments($sql)) #foreach ($user in $allUsers) $xwiki.getDocument($user).getDocument().resetArchive($context.context) #end How can i avoid to get the message 'a different object with the same identifier value was already associated with the session'. Can you give me an advice, please? I've had a bug in a scheduled job. As a result the user documents got updates each day. I have to reset the History of more than 1500 users to recover database space.
