Hi David - I've not seen or heard of this one before. Were you installing Merchello.Core or one of the Bazaar starters?

Maybe try setting the

Hmm - it just posted part of my message =)

May try setting the

 <compilation debug="true" 

in your web.config and also perhaps delete the contents of the App_Data/TEMP/PluginCache directory. Umbraco will just regenerate that.

Hi Rusty,

Thanks for your reply, apologies for my delayed response (I'm in Australia). The web.config setting for debug was already set to true and I've deleted the cache directory but no luck, the error still occurs. I installed Merchello from the Umrbaco package repository in back office.

If it helps any, I'm running Umbraco in VS 2013 Update 4 and installed Umbraco from nuget. I'll get some time today to download Merchello from Github and add it into my solution so I can see if something in Merchello is throwing the error or if it's inside Umbraco.

Cheers

Update - using Merchello source code and referencing those libraries still generates the error but no exception thrown in VS. I'm guessing it's because the exception occurs within Umbraco somewhere.

@David - in your web.config do you have a reference to the merchello section and then the merchello.config file? In the configuration file, we define the tree. Maybe something happened during the install and your web.config was not updated or the merchello.config file was not copied correctly?

Hi Rusty, 

I created a new empty MVC project, installed UmbracoCMS from nuget, ran it to install a starter site and the installed Merchello from Umbraco repository and it all worked correctly.  I compared the Web.config & merchello.config from that install with my existing install, and they are identical (where Merchello matters - SQL conn strings are different).

I wonder if I have a node created that shares a name Merchello uses internally?

Edit: I moved all my root nodes into the single "Home Page" node (I have a Site Settings root node for example) and still no change with Merchello.

Cheers

Hi Guys,

Have you sorted this out, because I am experincing the same issue with the latest Merchello Version... on Umbraco 7.4.1.

thank you

Kind Regards

The same for 7.4.3.

Installed Umbraco, Merchello and Merchello.FastTrack from nuget into a new project.

So in order to work, you are saying to install normally the umbraco package and then install the Merchello.Core from nuget in order to work?

Still not working :(

Same Error

Hi Rusty,

Thank you for your attention.

Yes, for sure, I have the folder mentioned (App_Plugins/Merchello) and everything is fine, config file etc....because I have verified..

BUT, I am suspecting that something from my global.Asax.cs is failing this, that in the backoffice, merchello is firing an error, as mentioned above.

private ConcurrentBag<Assembly> loadAllAssembliesManual()
        {
            var casaSoftProjectAssemblies = new ConcurrentBag<Assembly>();
            casaSoftProjectAssemblies.Add(typeof(CS.Common.Services.ServiceAttribute).Assembly);
            casaSoftProjectAssemblies.Add(typeof(CS.Common.Umbraco.Services.Umbraco.Wrappers.IUmbracoHelperService).Assembly);
            casaSoftProjectAssemblies.Add(typeof(Ingredis.Code.Constants.ConstantValues).Assembly);
            casaSoftProjectAssemblies.Add(typeof(Ingredis.BundleConfig).Assembly);

            return casaSoftProjectAssemblies;
        }

        protected override void OnApplicationStarted(object sender, EventArgs e)
        {
            LogHelper.Warn<Global>("Enter On Application Started");
            AreaRegistration.RegisterAllAreas();
            BundleConfig.RegisterBundles(BundleTable.Bundles);
            RouteConfig.RegisterRoutes(RouteTable.Routes);

            // container.Register<IRenderMvcController, RenderMvcController>(Lifestyle.Transient);
            IocHelpers.Container.Register(() => new RenderMvcController(), Lifestyle.Scoped);


            CS.Common.SimpleInjectorMvc.SimpleInjectorMvcInitializer.
                InitializeSimpleInjectorMvc(IocHelpers.Container,
                loadAllAssembliesManual(),
                logMessage);

            //register custom Data Annotation
            DataAnnotationsModelValidatorProvider.RegisterAdapter(typeof(RequiredIfAttribute),
                typeof(RequiredAttributeAdapter));

            LogHelper.Warn<Global>("On Application Started - Initiliases SimpleInjectorMVCInitializer");



            base.OnApplicationStarted(sender, e);


        }
        public override string GetVaryByCustomString(HttpContext context, string custom)
        {
            if (custom.InvariantEquals("url"))
            {
                return "url=" + context.Request.Url.AbsoluteUri;
            }

            return base.GetVaryByCustomString(context, custom);
        }

The other sections in the backoffice are working.. but I can't figuring out why Merchello is not working.

Can you help me sort this out please Rusty.

Thank you in advance.

Kind Regards

Hi Rusty, Thanks for your reply.

I am currently testing and debugging the problem and figured out that one I removed the following line of code, it is working:

DependencyResolver.SetResolver(new SimpleInjectorDependencyResolver(container));

I am using the SimpleInjector, as you can see for Dependency injection.

Any help will be much appreciated. In the meantime I will continue investigating it.

Thanks Kind Regards

Hi Rusty,

Any help about this?

There is something not working with Merchello when set the dependency resolver as a SimpleInjectorDepedencyResolover object.

I tried even with an empty container, for testing.. but the same error.

Appreciate any help.

Kind regards

Hi Rusty,

Any feedback on this please?
