    text
    copied!<p>I have a ViewModel wrapping two complex types:</p> <pre><code>public class EditProductViewModel { public ProductData ProductData { get; set; } public FridgeContent FridgeContent { get; set; } } </code></pre> <p>and this view:</p> <pre><code>@model EditProductViewModel @using (Html.BeginForm("Edit", "ProductData", FormMethod.Post)) { @Html.EditorForModel() [...] } </code></pre> <p>ProductData and FridgeContent contain POCO properties with DataAnnotations like this:</p> <pre><code>public class FridgeContentMetadata : DatabaseEntityMetadataBase { [Required] [HiddenInput(DisplayValue = false)] public int ProductDataId { get; set; } [Required] [UIHint("StringReadOnly")] public int ScaleId { get; set; } [Required] [UIHint("StringReadOnly")] [Range(0.01, float.MaxValue, ErrorMessage = "The weight of a product must be positive.")] public float Weight { get; set; } [...] } </code></pre> <p>I want to edit both ProductData and FridgeContent in the EditProductView using the appropriate data annotations from those classes and the EditorForModel() method (I don't want to generate the templates myself). I therefore created the templates ProductData.cshtml and FridgeContent.cshtml in /Views/Shared/EditorTemplates/:</p> <pre><code>@model FridgeContent @Html.EditorForModel() </code></pre> <p>Unfortunately, the view for EditProductViewModel is empty (no errors raised). If I use EditorForModel for either FridgeContent or ProductData alone, it's working fine. I also tried adding [UIHInt("..")] annotations to EditProductViewModel but that doesn't make a difference. </p> <p>What am I missing?</p>
