Description Johan Linde CLA 2010-08-16 04:00:41 EDT 
When trying to upgrade to CDO 3, I have run into a NullPointerException after deleting a resource (stack trace below). The delete is done by

resource.delete(null);

When commiting this change I get the exception. The variable "view" is null when the exception occurs. 

This exception never happened with CDO 2.
