Narrative:
I was conducting OJT at sector 42 at ZMA. My trainee was approaching his saturation point; with time based arrs into fll over the same fix as fxe and opf traffic. I assumed the frequency to expedite the traffic flow. During the transition; the trainee issued a descent to the FA20 to FL180. The data block did not get updated to show the new assigned altitude. I issued a turn and a climb to the B757 H120 and climb to FL190. When conflict alert activated; the aircraft were on diverging headings; H120 (B757) and H360 (FA20). I assumed that the FA20 had deviated from his clearance. In order to not have the FA20 return to his altitude and risk further conflict; I assigned a further descent to the FA20.

Title: ZMA CTLR EXPERIENCED OPERROR AT 18500 FT WHEN TAKING CTL OF A SECTOR BUT NOT AWARE OF A DESCENT CLRNC ISSUED BY THE STUDENT CTLR.
Narrative: I WAS CONDUCTING OJT AT SECTOR 42 AT ZMA. MY TRAINEE WAS APCHING HIS SATURATION POINT; WITH TIME BASED ARRS INTO FLL OVER THE SAME FIX AS FXE AND OPF TFC. I ASSUMED THE FREQ TO EXPEDITE THE TFC FLOW. DURING THE TRANSITION; THE TRAINEE ISSUED A DSCNT TO THE FA20 TO FL180. THE DATA BLOCK DID NOT GET UPDATED TO SHOW THE NEW ASSIGNED ALT. I ISSUED A TURN AND A CLB TO THE B757 H120 AND CLB TO FL190. WHEN CONFLICT ALERT ACTIVATED; THE ACFT WERE ON DIVERGING HDGS; H120 (B757) AND H360 (FA20). I ASSUMED THAT THE FA20 HAD DEVIATED FROM HIS CLRNC. IN ORDER TO NOT HAVE THE FA20 RETURN TO HIS ALT AND RISK FURTHER CONFLICT; I ASSIGNED A FURTHER DSCNT TO THE FA20.
