Hands at the Net

[officialtony]

I had the identical situation last night in a Jr. High game - as the Referee.
Team A hits their third hit into the top of the net. I am not sure if the ball would have cleared the net or not, but Team B blocker jumps to block and the force of Team A's hit pushes net and ball into blockers hands. Team B blocker, instead of holding her ground straight up, decides to attack the ball and hits the net with her hands as she drives the ball back to Team A side of court. I call a net violation - even though the ball may never have crossed over the net - because the ball was in play until either it hits the floor or a foul occurs. I believe that was the correct call.
Any interpretations?
