I just did a rebuild of a bo and the partial class after the rebuild had a blank namespace instead of what had been there before.



Also, I was doing this to get rid of the dreaded NULL error message when there is a null field in the result set. The default behavior of this is really less than useful - in fact it is a pain in the butt. So I thought that I would change the fields in the mapper to nullable generic. Having done so I get code like this:

public Nullable MIDDLENAME

{

get

{

object loValue;

loValue = this.CurrentRow["MIDDLENAME"];

if (loValue == DBNull.Value)

{

return (Nullable)null;

}

else

{

return (Nullable)loValue;

}

}

set

{

if (value.HasValue)

{

this.CurrentRow["MIDDLENAME"] = value.Value;

}

else

{

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

}

}

}



And the following error message when I try to compile:

The type 'string' must be a non-nullable value type in order to use it as parameter 'T' in the generic type or method 'System.Nullable'   



What now?
