4.6 UI OnBeginDrag event handler doesn't seem to work.

I’ve been having problems receiving the OnBeginDrag event when using it on a script with a 2DCollider and using Physics2D raycasting. The OnDrag and OnPointerDown events are received no problem, but OnBeginDrag is never received. Any ideas what might be causing this?

I have the same problem. Did you solve this?
