Cycles Hair Particle disappear in render after combing

I don’t know if this topic was already posted by someone, I tried to create lion’s fur with cycles hair particlesystem.

Everything works just fine in the render result until i comb the hair, it didn’t show up in the render result.
Btw, im using 2.70a. Is this a bug or i’m missing something? Anyone having same issue?

Never mind, I already figured it out. need to leave the particle edit mode before render. Sorry for making inconveniences
