Mario Ivankovits commented on VFS-77:
-------------------------------------

Could you please try the next nightly, then the message "Object didnt extend from AbstractFileObject. Object "{0}" " should show the correct object class name instead of {0}.

Though, I think it will be "null" which means that you have no permission to list the root directory of your ftp server - is this true?
If so, this is a enhancement which needs to be adressed.

Ciao,
Mario
