This code work well for a page: {{velocity}} $xwiki.getDocument('BacASable.TestPage3').getDocument().resetArchive($context.context) {{/velocity}} but my script fail when I launch this one to remove history of all BacASable space Page {{velocity}} #foreach ($docName in $xwiki.getSpaceDocsName("BacASable")) $xwiki.getDocument("BacASable.$docName").getDocument().resetArchive($context.context) * history of "BacASable.$docName" removed #end {{/velocity}} I obtain this error: Caused by: org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session: [com.xpn.xwiki.doc.rcs.XWikiRCSNodeInfo#com.xpn.xwiki.doc.rcs.XWikiRCSNodeId@2ff3ff58[docId=9026427162423984573,version=4.1]] Any ideas what's I'm doing wrong?
