SQL logic error near ")": syntax error - with Contrib

Hi
I've noticed that when making superclass as DAL containing CRUD operation with SQLite it always give this error
the code is like that

public abstract class DataEntity : IDisposable
{ 
        public virtual void Insert()
        {
                using (var db = ConFactory.Connection)
                {
                    db.Open();
                    var tr = db.BeginTransaction();
                    db.Insert(this, tr);
                    tr.Commit();
                }
        }
}

and my classes looks like that

[Table("[test]")]
   public class Test : DataEntity
   {
       [Key]
       public int TestId { get; set; }

       public string Name { get; set; }
   }

using the code like this will result SQL logic error near ")": syntax error

using (Test t = new Test { Name = textBox2.Text })
{
     t.Insert();
     textBox1.Text = t.TestId.ToString();
 }

BUT when Insert method dragged to [Test] class it works perfectly

Start by reproducing the SQLite insert with the abstract DataEntity.Insert method and compare it with the same method placed directly on Test. Trace how db.Insert(this, tr) determines the table and columns for the inherited object; done means both forms insert successfully and assign TestId without the syntax error.
