Hello!

I have a page type with a property that is an IList of items (used for a navigation if that is of interest):

        [Display(
            Name = "Main navigation",
            Order = 100,
            GroupName = PropertyTabs.Header)]
        [EditorDescriptor(EditorDescriptorType = typeof(CollectionEditorDescriptor<MainNavigationPropertyItem>))]
        public virtual IList<MainNavigationPropertyItem>? MainNavigation { get; set; }

The class used for the items contains a number of properties and also inherits another class in which there is a property of type ContentReference, to let the editor select pages to link to.

At the moment the editor can see all types of content in the selector. I want to limit it to only show pages, which can usually be done using  [AllowedTypes(typeof(PageData))]. 

I tried adding it in the same way as I would do for a property in a content model class:

public class MainNavigationPropertyItem : NavigationPropertyItem
{
  <...other properties>      
}

public class NavigationPropertyItem
{      
        [Required]
        [Display(Name = "Link to page", Order = 20)]
        [AllowedTypes(typeof(PageData))]
        public ContentReference? ContentLink { get; set; }
}

Although the AllowedTypes-attribute does not seem to work inside an IList?

Is this a bug? The Required and Display attribute that is on the same property is working.
Is there another way of making the select dialog only contain pages for a property in an IList?

Best regards,
Linda
