Hey Guys,

i have a problem. I could upload images just fine in media...

But recently i get the error when trying to upload an image.. It says Failed. When i'm hovering it says: "Unable to cast object of type 'Castle.Proxies.ImageFileProxy' to type 'EPiServer.Core.PageData'" What the hell??!? Where did that come from?

i have a class like so:

[ContentType(GUID = "0A89E464-56D4-449F-AEA8-2BF774AB8730")]
    [MediaDescriptor(ExtensionString = "jpg,jpeg,jpe,ico,gif,bmp,png")]
    public class ImageFile : ImageData 
    {
        [Editable(true)]
        [Display(
            Name = "Description",
            Description = "Description field's description",
            GroupName = SystemTabNames.Content,
            Order = 1)]
        public virtual String Description { get; set; }

        public virtual string Copyright { get; set; }
    }

This was working fine. We didnt update anything.. what am i missing ?

Do you have any listeners for events like contentsave of contentpublish?

The error points to some code you have that trying to do stuff when users are publishing or saving your content

Yes i have one...

[InitializableModule]
    [ModuleDependency(typeof(InitializableModule))]
    public class PublishEventInitialization : IInitializableModule
    {
        public void Initialize(InitializationEngine context)
        {
            //Debugger.Break();
            context.InitComplete += Context_InitComplete;           
        }

        private void Context_InitComplete(object sender, EventArgs e)
        {
            var events = ServiceLocator.Current.GetInstance<IContentEvents>();
            events.PublishedContent += Events_PublishedContent;
        }

        private void Events_PublishedContent(object sender, ContentEventArgs e)
        {            
            /// Push notification if it's a new Coupe being published           
            if (((PageData)e.Content).PageTypeName == "CoupePage")
            {
                PageData page = (PageData)e.Content;
                //first check if the pageId exists in the custom table, if not then sent notifications to the hub
                if(!NotificationHubHelper.Exists(page.ContentLink.ID))
                {
                    AzureNotificationsHubClient client = new AzureNotificationsHubClient();
                    bool androidSent = client.SendNewArticleAndroidNotificationsAsync(page.Name, page.ContentLink.ID);
                    bool iOSSent = client.SendNewArticleiOSNotificationsAsync(page.Name, page.ContentLink.ID);
                    
                    //after add the current pageId to the custom table
                    NotificationHubHelper.UpdateOrAdd(page.ContentLink.ID);
                }               
            }           
        }

        public void Preload(string[] parameters)
        {
        }

        public void Uninitialize(InitializationEngine context)
        {
            var events = ServiceLocator.Current.GetInstance<IContentEvents>();            
            context.InitComplete -= Context_InitComplete;
            events.PublishedContent -= Events_PublishedContent;
        }
    }

How can we improve this? The publish event should only fire if the page is of type "CoupePage"

Yes, there are the error.

To improve and make it work you need to wrap it with a test if it is the correct contentType

You can do it in many ways, but this is one:

private void Events_PublishedContent(object sender, ContentEventArgs e)
        {      
	    var coupePage = e.Content as CoupePage;

            if coupePage == null)
            {
                return;
            }
      
            
                PageData page = (PageData)e.Content;
                //first check if the pageId exists in the custom table, if not then sent notifications to the hub
                if(!NotificationHubHelper.Exists(page.ContentLink.ID))
                {
                    AzureNotificationsHubClient client = new AzureNotificationsHubClient();
                    bool androidSent = client.SendNewArticleAndroidNotificationsAsync(page.Name, page.ContentLink.ID);
                    bool iOSSent = client.SendNewArticleiOSNotificationsAsync(page.Name, page.ContentLink.ID);
                    
                    //after add the current pageId to the custom table
                    NotificationHubHelper.UpdateOrAdd(page.ContentLink.ID);
                }               
                
        }
