"Error reloading VRML file" when constructing RBM Visualizer

[anirudhamajumdar]

Had a email conversation with Russ about this. It could be that I'm not using the weldJoint function properly. But, I keep getting an error when I try to fix certain joints in a urdf and then construct a visualizer like this:

% Set up system % p = RigidBodyManipulator('SimpleHumanoid.urdf'); p = RigidBodyManipulator('AtlasModel.urdf'); v = p.constructVisualizer; p = p.weldJoint(7); p = p.compile(); v = p.constructVisualizer; p = p.weldJoint(7); p = p.compile(); v = p.constructVisualizer;

Warning: Error reloading VRML file.

To be clear, I suspect we are not updating the wrl geometry correctly when we weld the joints. (Most of us use the botvis visualizer, not wrl).

But it's on my list to look at.

i believe that this is resolved now in trunk. please test it and reopen this if I'm wrong.

Seems to be working fine on my example.
