I guess the simplest way is to not use the default selector and override
the resolution logic then.

Hi all,
It seems that if you resolve a component by name with the typed
factory facility, and that component doesn't exist, it will just
return one of the other components for the type you're resolving.
For example, the following program:
public interface IPerson
{
string Name { get; }
}
public class Jack : IPerson
{
public string Name { get { return "Jack"; } }
}
public class Bob : IPerson
{
public string Name { get { return "Bob"; } }
}
public interface IHumanFactory
{
IPerson GetJack();
IPerson GetBob();
IPerson GetFrank();
}
class Program
{
static void Main(string[] args)
{
var ct = new WindsorContainer();
ct.AddFacility<TypedFactoryFacility>();
ct.Register(AllTypes.FromThisAssembly().BasedOn<IPerson>().WithService.FirstInterface().Configure(x
=> x.Named(x.Implementation.Name)));
ct.Register(Component.For<IHumanFactory>().AsFactory());
var factory = ct.Resolve<IHumanFactory>();
Console.WriteLine(factory.GetBob().Name);
Console.WriteLine(factory.GetJack().Name);
Console.WriteLine(factory.GetFrank().Name);
}
}
Outputs:
Bob
Jack
Jack
This seems to be intentional behavior (changing this behavior causes
the Castle test named
Resolve_component_by_name_with_default_selector_falls_back_to_by_type_when_no_name_found
to fail), but I would rather it throw an exception or return null for
GetFrank in this example.
Thanks,
Cameron
