ExportDecorator with When.InjectedInto won't fire

[mgth]

If i do not put the condition Decorator is applied, but when When.InjectedInto is used the decorator is never applied.
I'm using a Func<param, IService> in the constructor.
Doing this with standard export works as expected but not with decorator.

@mgth I was able to replicate the bug. I'll see if I can fix it this weekend at some point and do a beta release.

@mgth I've released a pre-release version to nuget. Can you test it out?

[mgth]

Sorry, it still fail for me. But this is special case where I must use Container.Inject(obj);
Another thing is the decorator itself does not get injected.

@mgth you’ll need to put together a sample showing the issue.

[mgth]

    interface IService { }
    class MyService : IService { }
    class MyServiceDecorator : IService { }

    interface IMyClass { }
    class MyClass : IMyClass
    {
        [Import]
        public Func<IService> GetService { get; set; }
    }

    class Program
    {
        static void Main(string[] args)
        {
            var container = new DependencyInjectionContainer();

            container.Configure( c =>
            {
                c.Export<MyClass>().As<IMyClass>().ImportMembers();
                c.Export<MyService>().As<IService>();
                c.ExportDecorator(typeof(MyServiceDecorator)).As(typeof(IService)).When.InjectedInto<IMyClass>();
            });

            var myClass = new MyClass();
            container.Inject(myClass);

            // there getService will return a MyService when it should return a MyServiceDecorator
            var service = myClass.GetService();
        }
    }

when this will return a MyServiceDecorator as expected
var myClass = (MyClass)container.Locate<IMyClass>();

@mgth the reason it's not work the way you want it to is because the Inject method is an extension and isn't a first class feature in the container. No strategy is created for an injected type so the default implementation for WhenInjectedInto won't work.

I'm not inclined to make a change to the default behavior because it could have unintended side effects but you could do a custom condition like this.

[mgth]

Ok, that works. Thank you much for your precious time.

@mgth glad I was able to address your issue. I'm going to close this as fixed, if you run into anything more open an issue and I'll try and address it.

I'll plan on doing an official release near the end of this month.
