Change Soft Type Name Attribute

Does anyone know how to change the Name attribute of a soft type to a drop down list instead of a line to type on?  I changed the attribute to have an Enumerated Value List, Selection List Style to Drop Down and Input Field Type to Single Line.  I stopped and started my server and no change.  I am on 10.1 m040.  We want to control what names can be picked for a soft type document.

Thank you,

Brian
