I thaught I had replied to this post.

Here it goes again.

1. Attach the LOV to the field in the item property sheet.
2. Define a KEY-LISTVAL trigger on the field.
3. KEY-LISTVAL DECLARE item_selected BOOLEAN; BEGIN item_selected := SHOW_LOV; IF item_selected THEN << Enable/Disable push buttons. >> ELSE << Do processing when no item selected from the list. >> END;

Above trigger will work fine when the item has an LOV attached to it. However, if there is no LOV attached to the field, pass the name of the LOV to the SHOW_LOV( 'my_lov') function.

Hope this helps.
