Problem with Ninject and MVC3 Dependency injection action filter on Controller and Action

Question

Recently I decided to remove a heap of action level filters in a controller and replace them with a single controller level filter.

Now I'm getting this error message.

Error activating LogActionFilter
More than one matching bindings are available.
Activation path:
 1) Request for LogActionFilter

Suggestions:
 1) Ensure that you have defined a binding for LogActionFilter only once.

I'm sure the error is related to action filter being bound twice, as that's what I've changed. However, when I view the documentation here I can see it specifies/does the same. So I'm really not sure what I'm doing wrong.

My sample controller

[LogAction]
public class SomeController : Controller
{
    public ActionResult SomeAction()
    { 

    }
}

My registration code

public static void RegisterFilters()
{
    Kernel.BindFilter<LogActionFilter>(FilterScope.Controller, 0)
    .WhenControllerHas<LogActionAttribute>();

    Kernel.BindFilter<LogActionFilter>(FilterScope.Action, 0)
        .WhenActionMethodHas<LogActionAttribute>();
}

Answer 1

This happens if your controller and one of its actions have the LogActionAttribute at the same time.
