Hi all, using the "Copy a document" page with: - source document=XWiki.provaCopia - target document mySpace.provaCopia I get this result: - Copying document XWiki.provaCopia () from xwiki to xwiki: $xwiki.xWiki.copyDocument($sourcedoc, $targetdoc, $sourcewiki, $targetwiki, $language, false, $context.context) and the copy is not done.
