Triggers turning off gravity

I'm using the editor based gravity system. Similar if not exact to the ninja platformer tutorial.

When I include a trigger into the level and jump through it, it seemingly turns off gravity and the character maintains the vertical velocity it had when it entered the trigger. It's just a stock trigger too. No matter what the collision settings or call-back settings are on the trigger it maintains the players vertical velocity.

I may have to actually develop my jump function into something that is mine and not taken from a tutorial. All it does is set the vertical velocity and let gravity bring it back down to earth. Triggers for some odd reason disable the gravity's affect. I haven't found a solution yet though.

function Player.playerJump(%this, %level)
{
  if($myPlayer.getLinearVelocityY() <= 1 && $myPlayer.getLinearVelocityY() >= 0)
  {
    $myPlayer.setLinearVelocityY(-225);
  }
}
