Narrative:

After takeoff and initial power reduction; we got an ECAM F/control caution with the flaps locked. Upon selecting flaps up; the trailing edge flaps remained at F1. Slats retracted normally. Advised ATC and flight attendants. Captain flew aircraft and handled ATC. First officer ran checklists and talked to dispatch and maintenance. Aircraft checklists could not solve problem. Maintenance agreed with captain to return to field. Appropriate approach and landing checklists and charts were referenced. Aircraft weight was well under landing weight. A flaps 3 approach and landing were made. Slats were in 3 position. Flaps remained locked at the flaps 1 position. Landed safely without incident.callback conversation with reporter revealed the following information: the reporter stated that the aircraft had come from overnight maintenance prior to his flight. After the ECAM annunciation in-flight; discussions with maintenance had the crew cycling the flaps which did not clear the problem. The slats operated normally in-flight but the flaps remained locked at 1 degree. After landing; the crew cycled the flaps with the same results. Once they were at the gate; maintenance cycled the yellow hydraulic system; and as the flaps were cycled; the flaps locked ECAM was cleared. The crew refused the aircraft.
