[3.3.5a] Problem with DK - Death Grip spell when Jump

Hi, i ’ m using the latest Rev of TC for Wotlk. I was trying to fix the Death Grip spell of Dk, the spell can be used when the caster is jumping or falling and that its wrong.

The problem in my code is that i cannot make that the code check if the caster is jumping or not, i try with :

if (!player->HasUnitState(UNIT_STATE_JUMPING))

But not success, also i was tried with if (!player->IsFalling()) and i have the same result.

What i m doing wrong?

Sorry if its a noob question but i m learning.
Sorry about the bad english.
Thanks in advance, regards.

Fix for this already on core.
