[osg-users] osg::Billboard positions

I have an issue, might not be related to osg::Billboard it self.

At every frame, I delete all the drawables for a osg::Billboard:
tags->removeDrawables(0, size);

and I add them again, possible with different values for position:
tags->addDrawable(osg::Geometry, osg::Vec3(pos.x, pos.y, pos.z));

but in the view I still see the old positions of the tags!

Does OSG has some kind of cache? Do I have to invalidate something?
