A321 Captain experiences a flap system 1 fault after flap retraction and noticed that IGNITION remained on the upper ECAM. Maintenance Control is contacted for their input and the crew elects to divert for repairs.

Narrative

At flap retraction following takeoff - we received a flap system 1 fault. We checked the QRH then followed ECAM. We also noticed that IGNITION remained on the upper ECAM. Additionally; we had an ENG 1 approach idle only on the status page. We contacted Maintenance to verify that it is ok to fly for over 5 hours with the igniter's ON and the Eng Mode selector in NORM. Maintenance directed us to - in compliance with QRH - reset the FWC computers with no luck. Maintenance had us check the Engine page to see if IGN was on. We advised Maintenance that IGN was not displayed on engine page; but it also did not display when we selected eng mode on or selected the engine anti ice on. We were under the impression that IGN came on the ENG page only during start. Maintenance then informed us that the IGNITION on the upper ECAM was just a message and didn't mean the ignition was actually on. Further; Maintenance advised us that they believe that our ignition system was inhibited and would not turn on with engine anti ice nor when selected with mode selector. On the other hand; if we were right Maintenance advised that worse case scenario was that the igniter's would burn out. Dispatch gave us the option of continuing to destination or diverting. We elected to go to divert. Maybe the flap system 1 fault interrupted a signal to the igniter's to shut off after takeoff?
