Action Filter not firing

Feb 20, 2012 at 12:56 AM

After installing SimpleInjector.Mvc nuget package, Action Filter like [Authorize] no longer fires. If I comment out the below line, action filter starts working.


Is there any side effect of commenting out this line?

Hi, I incorrectly assumed that MVC would request an IFilterProvider from the dependency resolver, but it seems to get it directly from the static FilterProviders class. The RegisterAttributeFilterProvider method of the MVC NuGet package should have registered the SimpleInjectorFilterAttributeFilterProvider to the FilterProviders class. What you can do to fix this is, go to the definition of the RegisterAttributeFilterProvider method and replace the following line:
container.RegisterSingle<IFilterProvider, SimpleInjectorFilterAttributeFilterProvider>(); 
with the following:
FilterProviders.Providers.Add(new SimpleInjectorFilterAttributeFilterProvider(container));
I hope this helps.

It is working now.

A new version of the SimpleInjector.MVC3 NuGet package has been uploaded to NuGet. This package contains the fix and a few other minor changes. Please note that updating this package from the previous version will have no effect, since the NuGet package manager will not override an existing content file. If you are updating form a previous version of the SimpleInjector.MVC3 package, you will have to install it in a empty project and copy the SimpleInjectorMVC3Extensions.cs from the empty project to your real project.

I've got this exact problem. I'm using v1.4.2.12141 and this fix doesn't appear to be in the source.

I've even made the change here and it still doesn't fix it.

Any other ideas?

many thanks

Ah, I think I have it. I needed to add that line at the end otherwise the filter provider gets remove;

public static void RegisterMvcAttributeFilterProvider(this Container container)      
            if (container == null)
                throw new ArgumentNullException("container");

            var singletonFilterProvider = new SimpleInjectorFilterAttributeFilterProvider(container);

            var providers = FilterProviders.Providers.OfType<FilterAttributeFilterProvider>().ToList();

            providers.ForEach(provider => FilterProviders.Providers.Remove(provider));

            FilterProviders.Providers.Add(new SimpleInjectorFilterAttributeFilterProvider(container));

I just published a new version of the MVC3 Integration NuGet package that fixes this bug.
