[flexcoders] Bones and inverse kinematics on FLEX : where to find IKManager ?

[yarekc]

Hello
I have created a SWF with bones which works good.
When I do import it into Flex 4
<mx:Image src="bones.swf">

It is displayed, but bones are nort active.
I read that you need to import

import fl.ik.*

But FLEX does have theses classes !
Any way to have IK inside a FLEX application ?

regards
