Problem:

Field 'subsection' (in MVC model Artikel property below) contains null.

public List ArticleBody { get; set; }

I can't see what I did wrong. ISyndicationFeedItemProvider?

  • SDL Web Template builder does what expected (Pagetemplate with Page).
    'subsection' refers to an ArticleBody. It has fields title, text.
          "Content": {
            "title": "Lorem Ipsum",
            "intro": "MyIntro Neque porro quisquam est qui dolorem ipsum",
            "publishDate": "2020-11-11T21:38:06.455",
            "subsection": {
              "$type": "ContentModelData[]",
              "$values": [
                {
                  "title": "What is Lorem Ipsum?",
                  "text": "Lorem Ipsum has been the industry's standard dummy text ever since the 1500s,"
                },
                {
                  "title": "Why do we use it?",
                  "text": {
                    "$type": "RichTextData",
                    "Fragments": [
                      "<span style=\"color: rgb(0, 0, 0); font-family: &quot;Open Sans&quot;, Arial, sans-serif; font-size: 14px; text-align: justify;\">Curabitur id purus at urna efficitur aliquet auctor at tellus.

Sed sem ante, gravida et maximus sit amet, egestas a mi. Ut nec semper metus. Sed blandit lectus elit, et dapibus sem egestas suscipit. Praesent varius felis et sem ullamcorper porttitor.</span>"
                    ]
                  }
                },
                {
                  "title": "Where can I get some? ",
                  "text": "It uses a dictionary of over 200 Latin words, combined with a handful of model sentence structures"
                }
              ]
            }
          },
  • Schema Artikel (contains Embedded schema Paragraaf)

enter image description here

  • DXA models
    [SemanticEntity(Vocab = SchemaOrgVocabulary, EntityName = "Artikel", Prefix = "s", Public = true)]
    [Serializable]
    public class Artikel : EntityModel
    {
        [SemanticProperty("s:title")]
        public string Title { get; set; }
        ...

        [SemanticProperty("s:subsection")]
        public List<Paragraaf> ArticleBody { get; set; }
    [Serializable]
    public class Paragraaf : EntityModel
    {
        public string Title { get; set; }
        public RichText Text { get; set; }
    }

UPDATE:
I removed mymodule, and started again with content.
Is that possible?

It seems you want to map View Model property Artikel.ArticleBody (nice mix of Dutch and English, BTW) to a CM field called subsection.

That is possible using a [SemanticProperty] annotation, but you currently only have one for the schema.org Vocabulary (which doesn’t define a type called “Artikel”, BTW), whereas you should use the Core Vocabulary for CM mapping. So: try adding [SemanticProperty(“subsection”)] (and remove the schema.org annotations for simplicity).
