I use the following code to grant Delete right by default (I execute this java code on xwiki start): XWikiContext context = contextProvider.get(); if (context != null) { XWiki xwiki = context.getWiki(); DocumentReference dr = new DocumentReference("xwiki", "XWiki", "XWikiPreferences"); XWikiDocument doc = xwiki.getDocument(dr, context); BaseObject bo = doc.getObject("XWiki.XWikiGlobalRights", true, context); bo.set("groups", "XWiki.XWikiAllGroup", context); bo.set("levels", "view,comment,edit,delete,script", context); bo.set("users", "", context); bo.set("allow", 1, context); xwiki.saveDocument(doc, context); } I have strange effect: while I do have Delete right by default, documentTree macro doesn't work, I see spinning circles. I also have the following message in the xwiki terminal: Exception in macro #handleDocumentTreeRequest called at 13:xwiki:XWiki.DocumentTree[line 3, column 1 <http://xwiki.475771.n2.nabble.com/file/n7599540/xwiki_problem.jpg> How to fix the problem? -- View this message in context: http://xwiki.475771.n2.nabble.com/documentTree-macro-doesn-t-work-after-add… Sent from the XWiki- Dev mailing list archive at Nabble.com.
