Narrative:
After having the flap switches worked on by maintenance we got a 'flaps' takeoff warning before takeoff (in checklist). The captain visually confirmed the flap position and declared it safe to takeoff. After an uneventful takeoff, once at cruise altitude, he checked the MEL and realized that we should have had the warning fixed. The decision was not made to willfully disregard the safety. Rather, was made in haste in the #1 takeoff position with other aircraft waiting. Prevention: take the time to check the books out even if it causes inconvenience. Make sure what you're doing is 'legal,' as well as safe.
