Have you looked at this article?
So, the next question is, why are you using CSS Selector? Is this an object that cannot be idenfied via Object Browser or Object Spy and, therefore, unable to be mapped via NameMapping?
The tested object can be identified via Object spy, but it has no unique criteria for the identification.
I will accept your solution, i think there is no other way.
It may not have a single property but there may be a combination of properties that sets it apear from others. You say you want to use the CSS Selector. Those properties are also accessible for NameMapping.
