Problem

* When opening a your configuration in Policy Studio v 7.1.1, you get an error saying "Unable to connect to the URL provided" and then referencing a federated file on your local disk drive.

Resolution

-- This may be caused by using a - (minus sign) inside a selector--the ${some.name.here} expressions that are expanded to other values.  The problem with using a minus sign is that the value inside the selector is then misinterpreted as a mathematical expression, which ultimately results in a null pointer exception.  This error has been fixed in 7.2.0 and policies with the error may be upgraded to that version without incident.
