SQL Server 2005 -53, AdventureWorks database, User Tables, Create Table dialog

Create a column of type varchar and try to assign a default value 'hello'. Once you click away from the Default Value cell or press ENTER, the cell is set empty, i.e. the list is not editable and it's impossible to set a default value.

The same problem occures in Sybase ASE and in Oracle Create Table, Storage tab, Parallel option. They all use EditableListOption.

There were modifications in the upper class ListOption, look at setValue method. Line 57 has a comment: // make sure the item is actually in the list. Does it have something to do with the list not being editable?
