Offensive/defensive rebounding fouls?

[Pirate]

Although I've been a coach for the last 18 years, I'm in my first year of officiating. A veteran official posed this question to me at our meeting the other night. What's your call if A1 has released the ball for a try, but before the ball goes in the basket:

1.) B1 fouls A2 battling for rebound position
2.) A2 fouls B1 battling for rebound position

I say the basket is good in both instances with A getting the ball out of bounds nearest the foul in situation 1 and B getting it out of bounds in situation 2.
Our veteran official agreed with my decision in the first situation, but disagreed in situation number 2. He contended that the foul by the offense in situation 2 made the ball dead immediately and wipes out the basket. I have never seen this situation called in my 18 years as a coach. The rule book (exception 6-7-7) says that a foul (other than player control) does not cause the ball to become dead until the try or tap ends. Help, and thanks.
