It's me again. As I mentioned before, $request.getContextPath() and $context.getDatabase() cannot be parsed correctly. So I changed them into fixed value in resources/js/xwiki/xwiki.js as below: /** * XWiki namespace. * TODO: move everything in it. * * @type object */ var XWiki = { constants: { /** * Current wiki. */ //currentWiki: "$context.getDatabase()", currentWiki: "xwiki", /** * Main wiki. */ mainWiki: "$context.getMainWikiName()", /** * Context path. */ //contextPath: "$request.getContextPath()", contextPath: "https://www.denver.com/xwiki" And now I can get the tree, but also one error message displayed: http://n2.nabble.com/file/n3261097/image003.jpg I have no idea about the error and the point why $request.getContextPath() and $context.getDatabase() cannot be parsed. Thanks so much! -- View this message in context: http://n2.nabble.com/WYSIWYG-editor-link-function-cannot-work-tp3254443p3261... Sent from the XWiki- Users mailing list archive at Nabble.com.
