It occurs when editing by code an attribute which is normally set by GUI. As I don't want the user to be restricted by the GUI choice of color when editing by code, this issue will raise. The question is do we want this kind of situation to be fixed downstream or upstream. Upstream it will be useful in other similar situation. Fixing downstream can help to make some smart things, as adding the a morph color to the dropdownlist, but it will not be a generic solution. It can be handled in DropDownButtonMorph by catching the error, but I find this inelegant, but may be it is not the case.
