IDataSourceKeyResolver example

I am thinking of use IDataSourceKeyResolver for dynamic Connection strings handling.
I got test solution from here:
http://drc.ideablade.com/xwiki/bin/view/Documentation/code-sample-custom-datasourcekeyresolver
but it does not work.

I have the following situation:

* ServerModelTomato.Tomato entity have attribute:
[IbEm.DataSourceKeyName(@"Tomato")]

* Console01. Program execute this:

      var entityManager = new DomainModelEntityManager(true, "Customer01");
      foreach (var tomato in entityManager.Tomatoes) {
        Console.WriteLine("Tomato {0}", tomato.Variety);
      }

* During first call to entityManager.Tomatoes, CustomDataSourceKeyResolver.GetKey method invoked 
and proper 'Tomato_Customer01' ClientEdmKey generated along with proper connection string.

* Then the error raised:
The connection string for Key 'Tomato_Customer01' was not found or is invalid.  Check that either a connectionStrings element or EdmKey is defined for this key in the configuration file, or implement a custom IDataSourceKeyResolver.

It seems that dynamically created ClientEdmKey was ignored or lost somewhere.

Is this a bug or I have missed something?
