BindHttpFilter called twice, not only when IFilterBindingInNamedWithOrOnSyntax condition is true

[brenovieira]

I have these bindings in NinjectModule:

this.Bind<IBar>().ToMethod(ctx => new Bar()).WhenTargetHas<BarAttribute>();
this.Bind<IBar>().ToMethod(ctx => new Bar2());

When I inject IBar, Ninject correctly injects new Bar() when there's BarAttribute and
injects new Bar2() without BarAttribute.

For instance,

public class BarController
{
   public BarController([Bar]IBar bar) {} // injects new Bar()
}
public class Bar2Controller
{
   public Bar2Controller(IBar bar) {} // injects new Bar2()
}

But using BindHttpFilter, this "chain" behavior is different..

this.BindHttpFilter<FooAttribute>(FilterScope.Action)
   .WhenActionMethodHas<AllowAnonymousAttribute>()
   .WithConstructorArgument("foo", (object)null);
this.BindHttpFilter<FooAttribute>(FilterScope.Action);

public class FooController
{
   [AllowAnonymous]
   public Method() {}
}

public class FooAttribute : AuthorizeAttribute
{
   public FooAttribute(IDependency dependency) {}
}

When I request /foo/method, Ninject calls FooAttribute twice and injects null (using first binding) as expected, then instantiates FooAttribute again with IDependency binding.

What I expected was Ninject.Webapi chain the conditions and solve at the first match, as it does with normal Bind<>.

To solve my need (inject some paremeter when action is decorated with [AllowAnonymous], and another parameter when action isn't decorated with [AllowAnonymous]), I need to create mutual exclusive conditions which is a bad to maintain these two behaviors with Ninject Bind<> and Ninject.Web.WebApi BindHttpFilter<>:

this.BindHttpFilter<FooAttribute>(FilterScope.Action)
   .WhenActionMethodHas<AllowAnonymousAttribute>()
   .WithConstructorArgument("foo", (object)null);
this.BindHttpFilter<FooAttribute>(FilterScope.Action)
   .When((httpConfig, actionDescriptor) => !actionDescriptor.GetCustomAttributes<AllowAnonymousAttribute>().Any())

What do you think ?
