If a field has a Null Type of "Return and Set Alternate on Null..." and the Property Changing Events (either single or multiple) are generated, then the following code is generated.



public System.String FIELD1

{

get

{

object loValue;

loValue = this.CurrentRow["FIELD1"];

if (loValue == DBNull.Value)

{

return "";

}

else

{

return (System.String)loValue;

}

}

set

{

MyBOFieldChangingEventArgs e = new MyBOFieldChangingEventArgs(MyBOFieldNames.FIELD1, value);

this.OnFieldPropertyChanging(this, e);

if (value != "") <=== w00t*** Note: e is not used!!!! ***

{

this.CurrentRow["FIELD1"] = value;

}

else

{

this.CurrentRow["FIELD1"] = DBNull.Value;

}

}

}





The e.FieldValue is not used after returning from the event!!!! The e.FieldValue should be cast/set to value (as it is if the field is not nullable.)
