Hi,
I have an application which makes use of Windsor's child container feature
extensively. Recently, I fall into the following problem:
- Component Root has one dependency which is Branch.
- Root is registered into the parent container.
- Branch is registered into the child container.
- Problem: child can resolve Branch successfully but fail to resolve Root.
I guess the default behavior of Windsor is that it is resolving a service
which is registered to a container A, it won't look for dependency
registrations in the child containers of A.
Could anyone help me with a couple of questions:
1. Why is that chosen as the default behavior?
2. How do I make resolving Branch work?
Thank you,
Thuan.
Test code:
public interface IRoot { }
public interface IBranch { }
public class Root : IRoot
{
public Root(IBranch branch)
{
}
}
public class Branch : IBranch
{ }
[TestMethod]
public void TestWindsorChildContainer()
{
var container = new WindsorContainer();
container.Register(Component.For<IRoot>().ImplementedBy<Root>());
var child = new WindsorContainer();
child.Parent = container;
child.Register(Component.For<IBranch>().ImplementedBy<Branch>());
Assert.IsNotNull(child.Resolve<IBranch>()); // this is ok
Assert.IsNotNull(child.Resolve<IRoot>()); //
HandlerException: Can't create component 'Root' as it has dependencies to
be satisfied.
}
