Selected Entity on Task screen seems to save the data, but not display on the screen

Hi,

You must decorate your field(s) with [PXFieldDescription] attribute in order for it to be displayed in the Related Entity Description field.  See sample below:

  [Serializable]
  [PXCacheName("MyCustomTable")]
    [PXPrimaryGraph(typeof(Test))]
  public class MyCustomTable : IBqlTable
  {
    #region Id
    [PXDBIdentity]
    public virtual int? Id { get; set; }
    public abstract class id : PX.Data.BQL.BqlInt.Field<id> { }
    #endregion

    #region Name
    [PXDBString(50, IsKey = true, IsUnicode = true, InputMask = "")]
    [PXUIField(DisplayName = "Name")]
      [PXSelector(typeof(Search<name>), DescriptionField = typeof(lastName), ValidateValue = false)]
      [PXFieldDescription]
    public virtual string Name { get; set; }
    public abstract class name : PX.Data.BQL.BqlString.Field<name> { }
    #endregion

    #region LastName
.....................................
    #region Noteid
    [PXNote( ShowInReferenceSelector = true,
            Selector = typeof(MyCustomTable.name),
            DescriptionField = typeof(MyCustomTable.name))]
    public virtual Guid? Noteid { get; set; }
    public abstract class noteid : PX.Data.BQL.BqlGuid.Field<noteid> { }
    #endregion

See in the UI:

Hope this helps.
