permission errors

[vjxataface]

During incorporating permissions to my xataface website, as detailed in getting started guide
Home > Documentation > tutorial > Getting Started with Xataface > Permissions

i am getting following error

Fatal error: The role '' is not a registered role. in D:\xampp\htdocs\bhiwadi1\xataface\Dataface\PermissionsTool.php on line 558

Looks like you are calling getRolePermissions() with an empty role. Without seeing your source it's hard to comment further.

By "source", I mean the delegate class. Specifically any getPermissions() implementations you have added.
