Hi,

I'm trying to get a ProductFieldTypeProvider to work. I have started with the class below and thought that it should show up in the list field types. But it don't. I need to create a product field type where I can select UserGroups. 

Are there any basic exmaples of a ProductFieldTypeProvider somewhere perhaps?

namespace Softgear.Industrilas.Data.Provider
{
    [AddInName("Mindflower.UserGroupSelectProvider")]
    [AddInLabel("User Group Selector")]
    [AddInActive(true)]
    [Serializable]
    public class UserGroupSelectProvider : ProductFieldTypeProvider, IDropDownOptions
    {
        private Lazy<Dictionary<string, string>> _options;

        public UserGroupSelectProvider()
        {
            _options = new Lazy<Dictionary<string, string>>();
        }

        public override object GetValue(object value, string languageId, Dictionary<string, string> settings)
        {
            return "Testing usergroups";
        }

        public override string GetAppenderInfo(string languageId, string settings)
        {
            return GetAppenderInfo(languageId, GetParameterValues(settings));
        }

        public override string GetAppenderInfo(string languageId, Dictionary<string, string> settings)
        {
            return "AppenderInfo";
        }

        protected override void Render(TextWriter writer, string id, bool enabled, string value, bool hasError, string text, string title)
        {
            throw new NotImplementedException();
        }

        [AddInParameter("Usergroups")]
        [AddInParameterEditor(typeof(UserGroupParameterEditor), "multiple=false;")]
        [AddInParameterGroup("Source")]
        public string[] Usergroups { get; set; }

        public Hashtable GetOptions(string dropdownName)
        {
            // Get Hashtable
            Hashtable options = new Hashtable();

            foreach (var key in _options.Value.Keys)
            {
                options.Add(key, _options.Value[key]);
            }

            // Return the hashtable
            return options;
        }

    }
}
