[xwiki-devs] Multiple Rights : Space

Hi Regarding permissions when creating a new space : //add the rights for the group XWikiDocument spaceDoc = context.getWiki().getDocument(newspace.getSpaceName()+ "." + "WebPreferences", context); BaseObject rightsObject = spaceDoc.getObject("XWiki.XWikiGlobalRights", false, context); rightsObject.setLargeStringValue("groups", "XWiki.".concat(MyGroupName)); rightsObject.setStringValue("levels", "view,comment,edit"); rightsObject.setLargeStringValue("users", ""); rightsObject.setIntValue("allow", 1); spaceDoc.setMetaDataDirty(true); context.getWiki().saveDocument(spaceDoc, context.getMessageTool().get("core.comment.createdUser"), context); context.getWiki().getGroupService(context).flushCache(); context.getWiki().flushCache(); //add the rights for the admin spaceDoc = context.getWiki().getDocument(newspace.getSpaceName()+ "." + "WebPreferences", context); rightsObject = spaceDoc.getObject("XWiki.XWikiGlobalRights", false, context); rightsObject.setLargeStringValue("groups", ""); rightsObject.setStringValue("levels", "view,comment,edit,delete,admin"); rightsObject.setLargeStringValue("users", "XWiki.".concat(MyuserName)); rightsObject.setIntValue("allow", 1); spaceDoc.setMetaDataDirty(true); context.getWiki().saveDocument(spaceDoc, context.getMessageTool().get("core.comment.createdUser"), context); Only the second part works, the first part is overwrited by the second, so, how can i set one level(s) for a group and another level(s) for a user ? Thanks !
