Could not contact the following nodes: * /joint_state_publisher

Question

Hi there!

I'm having a problem when I launch RVIZ with a join_state_publisher. For exemple, when I do the tutorial from this page (Building Movable Robot Model with URDF) and I close it.

When I execute roswtf, appears that message:

"ERROR: Could not contact the following nodes: * /joint_state_publisher"

If I try to kill them with rosnode kill /joint_state_publisher it seem's that be OK, but if I rerun it I gave the same message.

I think that this is important because in next reruns of RVIZ it doesn't works correctly (the model not appears completly).

Any idea?

I forgot to add in my launch file the correct path for the joint_state_publisher and set the gui parameter to true.

Finally, my launch file looks like this:
