I am using Umbraco 7.6.3 and UI-O-Matic seems to works fine so far - however when I choose "UIOMatic dropdown" for a Document Type Property, the "Value property" and "Column to sort on" do not populate with any of the objects fields when I am in the Document Type Dialog. They do show up if I go to Developer - Property Types.

However when i select a Person, when i am on a page the person is not saved - What am i doing wrong, do you think?

Here is my Person class:

[UIOMatic("people", "People", "Person", FolderIcon = "icon-users", ItemIcon = "icon-user", RenderType = UIOMaticRenderType.List)]
[TableName("People")]
public class Person {
    [PrimaryKeyColumn(AutoIncrement = true)]
    public int Id { get; set; }

    [Required]
    [UIOMaticListViewField(Name = "First name", View = UIOMatic.Constants.FieldViews.Label)]
    [UIOMaticField(Name = "First name", Description = "Enter the persons first name", View = UIOMatic.Constants.FieldEditors.Textfield)]
    public string FirstName { get; set; }

    [Required]
    [UIOMaticListViewField(Name = "Last name", View = UIOMatic.Constants.FieldViews.Label)]
    [UIOMaticField(Name = "Last name", Description = "Enter the persons last name", View = UIOMatic.Constants.FieldEditors.Textfield)]
    public string LastName { get; set; }

    [UIOMaticField(Name = "Picture", Description = "Select a picture", View = UIOMatic.Constants.FieldEditors.File)]
    public string Picture { get; set; }

    [UIOMaticField(Name = "Biog", Description = "Enter the persons biography", View = UIOMatic.Constants.FieldEditors.Rte)]
    public string Biog { get; set; }

    [UIOMaticListViewField(Name = "Job title", View = UIOMatic.Constants.FieldViews.Label)]
    [UIOMaticField(Name = "Job title", Description = "Enter the persons job title", View = UIOMatic.Constants.FieldEditors.Dropdown, Config = "{'typeAlias': 'titles','valueColumn': 'Id','sortColumn': 'Name','textTemplate' : '{{Name}}'}")]
    public int JobTitle { get; set; }

    public override string ToString() {
        return FirstName + " " + LastName;
    }

}
