Attacking accross the net

[lightenup]

I had a couple of instances that were the other way over the weekend. First time, ball was passed up tight on the to where it touched the net, at that time was blocked by the player on the other side. Coach jumped up and said his player had the right to set the ball first which was incorrect, because once the ball touches the net, I consider that to be breaking the plane.

Second instance. once again, ball is passed up tight to the net. Setter hustles and tries to make a set but pushes it into the top of the net where it is then blocked staight down. Coach again complains that the set cannot be blocked.

Is my view correct on both instances?
