    Rendering nested content with items with content picker property: Argument 1: cannot convert from method group to HelperResult

    Hi forum,

    In a template for my slideshow document type I want to render all the items added to a Nested content property:

    • In the slideshow document type I have a property called slides
    • slides property is a Umbraco.NestedContent datatype with one document type (nested_slides) in its configuration
    • nested_slides document type has two properties: slide (content picker data type) and foo (textstring - used just for testing/debugging)

    In my template I have this code:

    @inherits Umbraco.Web.Mvc.UmbracoViewPage
    @using ContentModels = Umbraco.Web.PublishedModels;
        Layout = null;
        var items = Model.Value<IEnumerable<IPublishedElement>>("slides");
        foreach(var item in items)
            var slide = item.Value<IPublishedElement>("slide");
            var foo = item.Value<string>("foo");
            <p>slide: @slide.Id, foo: @foo</p>

    The code above is for proof of concept, but it gives an error in line 14:

    Server Error in '/' Application.
    Compilation Error
    Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.
    Compiler Error Message: CS1503: Argument 1: cannot convert from 'method group' to 'HelperResult'
    Source Error:
    Line 12:        var foo = item.Value<string>("foo");
    Line 13:        
    Line 14:         <p>slide: @slide.Id, foo: @foo</p>
    Line 15:     }
    Line 16: }

    I want to get the id of the linked node so I can call Umbraco.Content to get the content of that linked node.

    What am I doing wrong?

    Just encapsulate it in brackets and it works.
