Null values in Transfer are covered in the wiki: see http://docs.transfer-orm.com/wiki/Handling_Null_Values.cfm
If you have nullable="true" for a property and you set the property to an empty string, the corresponding column will be set to NULL on save. When you read the column back, the property is populated with an empty string. If you have nullable="false" for a property and you set the property to an empty string, the corresponding column will be set to an empty string on save. When you read the column back, the property is populated with an empty string. If you want to be able store both NULLs and empty strings in the same column, you must set the nullvalue attribute to some other string that will never be used for a real value. Keep in mind that if you do this, calling the getter method on the property when it contains a NULL will return whatever string you chose for the nullvalue attribute, and if you ever call the setter method with that nullvalue value, the column will be set to NULL on save (not the nullvalue value).
