Does using Whirlwind Attack prevent attacks of opportunity?

[Ravingdork]

Is it possible to use Whirlwind Attack to trip everyone within your reach and then use Greater Trip to attempt to attack them? (Provided you have Combat Reflexes and enough attacks of opportunity of course.)

I ask because that is the way our group has played it for some time now, particularly with my latest character Macellano Alemander. I know several other people on these very forums also play it that way (though whether that is out of blissful ignorance or choice, I'm not sure).

However, someone in another thread pointed out that this may not work, due to Whirlwind's language, specifically this part:

When you use the Whirlwind Attack feat, you also forfeit any bonus or extra attacks granted by other feats, spells, or abilities.

I was thinking that would prohibit things like Haste, a speed weapon, or Cleave. For some reason, I never thought to apply it to Greater Trip.

Personally, I'm inclined to believe that it DOESN'T apply to Greater Trip since they are attack of opportunities, not bonus attacks (like Medusa's Wrath, which specifically refers to the extra attacks as bonus attacks). Whirlwind Attack doesn't prevent you from making other attacks of opportunities, so naturally, it wouldn't apply here either, right?

I'm obviously biased on the matter. The more I think about it, the more it feels like I'm really reaching. So I thought I'd see what the community consensus was, and perhaps even get a developer comment if we're lucky.

So, what's the verdict?

Attacks of Opportunity are granted by an Attack of Opportunity Provocation.

Greater Trip doesn't give you an Attack, it causes the opponent to Provoke, which is something else entirely.

If someone ELSE used Greater Trip, you'd still get the AoO (assuming you were in reach) because again, it's not the feat that's granting the Attack, it's the Provocation that opens up the target.

Combat Reflexes doesn't give you attacks, it gives you AoOs that can only be spent if an opponent provokes.

I would interpret it as you do/want to Ravingdork. Its not creating a bonus attack its simply making your opponent provoke, if you had no aoos left you would not get a bonus one. Its possible you could count the extra attacks of opportunity granted by combat reflexes as extra attacks granted by a feat, but I think that's reaching past the RAW.
