I have created a custom fieldtype for Umbraco Forms based on the FileUpload fieldtype which will place the uploaded item into the Media section, so it can be automatically linked to a content node created by the submitted form data.

I have defined some settings, which I can see in the Umbraco Forms editor, but in my code file, the properties are always NULL.

If I debug and look at "this.Settings()" - I see the custom Settings listed.

Is my configuration incorrect?

Simplified code:

namespace MySite.Forms.FieldTypes
{
    using System;
    using System.IO;
    using System.Drawing;
    using System.Collections.Generic;
    using System.Linq;
    using System.Web;
    using Umbraco.Core;
    using Umbraco.Core.Models;
    using Umbraco.Core.IO;
    using Umbraco.Core.Logging;
    using Umbraco.Forms.Core;
    using Umbraco.Web;

    public class MediaUpload : Umbraco.Forms.Core.Providers.FieldTypes.FileUpload
    {
        const int ImageMediaTypeId = 1032;

        [Umbraco.Forms.Core.Attributes.Setting("Allowed file extensions",
             description = "Allowed file extensions (CSV)",
             alias = "AllowedExtensions")]
        public string AllowedExtensions { get; set; }

        [Umbraco.Forms.Core.Attributes.Setting("Media Parent ID",
             description = "ID of the parent where the media will be saved",
             alias = "MediaParentId")]
        public string MediaParentId { get; set; }

        public MediaUpload()
        {
            //Provider
            this.Id = new Guid("84f24c36-103d-4161-b2ec-058e57e315f2");
            this.Name = "Media Upload";
            this.Description = "Upload file to Umbraco Media Section";

            //FieldType
            this.Icon = "icon-cloud-upload";
            this.DataType = FieldDataType.Integer;

            var settings = this.Settings(); //<---This shows the settings when checked...
            var test = settings.Count;
        }


        public override IEnumerable<object> ProcessSubmittedValue(Umbraco.Forms.Core.Field AssociatedField, System.Collections.Generic.IEnumerable<object> Values, System.Web.HttpContextBase HttpContext)
        {
            List<Object> vals = new List<object>();

            var parentId = this.MediaParentId; //<--- This is always NULL

            // Do stuff with submitted file...

            return vals;
        }

        public override IEnumerable<object> ConvertToRecord(Field field, IEnumerable<object> postedValues, HttpContextBase context)
        {
            List<Object> vals = new List<object>();

            //Do Stuff

            return vals;
        }

    }
}
