title: Box2dWeb Revolute Joint falling through the ground
body: <p>I've been gradually trying to get my head round Box2dWeb, once you get your head round the basics it seems to become very rewarding quite quickly which is great. I can simulate the angry birds effect throwing objects across the page and into structures. I've been taking inspiration from Seth Ladd's great box2d tutorials and trying to adapt them so I can build a level editor where I can begin to create mini side scrolling games. BUT..i've fallen at the first hurdle.....</p>
  
  <p>My Revolute Joint is visible in debug (light blue line between the two bodies). However as it drops towards the floor the joint itself seems to carry on falling(off the canvas) when the bodies themselves collide and stop on the ground. Its as if they are actually not associated with each other at all.</p>
  
  <p>Can anybody explain what exactly I'm doing wrong?</p>

  <p>Feedback is greatly appreciated, I'm learning so be as critical as you like.</p>
  
  <p>Many thanks,
  Gary</p>

  <p>Just to update I have now sorted the issue, there seemed to be no fixtures attached to any of the bodies. (Thanks iforce2d) I've up'd 1 your comment but can't seem to accept in the normal way I would accept an answer.</p>
