Only one skeleton detected

[thomasgirault]

I am using ofxKinectCommonBridge + Kinect SDK 1.8 and I tried to display several skeleton with following loop :

for( int i = 0; i < kinect.getSkeletons().size(); i++) kinect.drawSkeleton(i);

Unfortunately, it only displays one skeleton whereas 2 skeletons would be displayed with the Kinect SDK.
