couple situations to check on

[refinks]

Sorry guys, haven't been back to check in for a few days, but I'm totally confused. Let me run the situation by you one more time, because I feel like I'm getting conflicting answers. In situation 2, the setter started in the back row, came in front of the 10 foot line, jumped to quick set the ball which was entirely above the height of the net, and very shortly thereafter, another player jumped to spike the ball which was entirely above the net. My understanding of the rule is once the ball completely crosses the net, the attack is completed. Because of this, I call an illegal back row attack. Maybe I'm misreading the posts, but it seems like some of you are saying I was correct, while others say I was incorrect.

Maybe it would help if I had a rules reference to the play in question and I could look up the rule, because I'm just as confused, and I've gotten no help from the officials I know locally, who seem to be just as conflicted.
