The property "AuditFields" does now appear on the BOs that inherit from the Base BO but the caption "Collection" does not show and when I click on the eclips I get the follow error:
"An error occurred while attempting to load this type editor: Object reference not set to an instance of an object."
Again, my hope here, is that you may be able to provide any information that may assist. I have successfully integrating the Auditing into our BaseBO as well as a ActivityLog viewer. My last goal is the creating of a property to allow the user to select none or select what fields they want to include. In addition I have some other plans for this but need to know what I may need to consider.
public class AuditField : IRequiredField
{
#region
" Declare Privates "
private string _FieldName;
#endregion
private SqlDbType _FieldType;
#region
" Declare Public Properties "
/// <summary>
/// The field name that is required
/// </summary>
/// <value></value>
/// <remarks></remarks>
public string FieldName
{
get { return _FieldName; }
set { _FieldName = value; }
}
/// <summary>

public SqlDbType FieldType
{
get { return _FieldType; }
set { _FieldType = value; }
}
