Another :
If I add 2 listeners with same type on a pivot3D, then remove 1 of them, the other stop being triggered.
Example :
with var piv : Pivot3D;
piv.addEventListener(Pivot3D.ENTER_FRAME_EVENT, func1);
piv.addEventListener(Pivot3D.ENTER_FRAME_EVENT, func2);
piv.removeEventListener(Pivot3D.ENTER_FRAME_EVENT, func1);
then func2 doesnt trigger anymore. Maybe it is bad coding, but I guess it should work no ?
