- Attributes
Remarks
The keypath is separated by dots, and each component is used to lookup a specific key on the object. The process is repeated on each returning object until the last element is processed.
If a component of the key path is not found, the method ValueForUndefinedKey(NSString) is invoked, and its default implementation raises an Objective-C exception. Subclasses can alter this behavior by overriding that method.

return (string) order.ValueForKeyPath ("user.address.phone.mobile");
