but...  can I display directly in rviz a "sensor_msgs/LaserScan" message ??
or I need too the "/tf [tf/tfMessage]"

because in the tutorial of
*
http://www.ros.org/wiki/laser_pipeline/Tutorials/IntroductionToWorkingWithLaserScannerData#Visualizing_Your_Laser_Scan,
*

I can display the data in rviz without problem (using laser.bag -->
http://vault.willowgarage.com/wgdata1/vol1/wiki_docs/laser_pipeline/laser.bag).

But with the code of this example
   "*
http://www.ros.org/wiki/navigation/Tutorials/RobotSetup/Sensors#Writing_Code_to_Publish_a_LaserScan_Message
*",

I have problems to display the fake data generated by this code.

Why????

Best regards.
