Yafray halos and particle emiters

Hey i keep getting a problem with yafray. It wont render my particles from my particle emiter. Does yafray not recognize the partcles from the emiter? I noticed in the blender dos screen it doesn’t say anything about them. I hope I dont have to do any layering.

YafRay doesn’t render Halos (which are used for particles unless you use dupliverts).
