Scan topic is not published

I am working with slam_gmapping, and When I launch the pointcloud to laser scan with this file, I do the following steps:

<launch> <include file="$(find openni_camera)/launch/openni_node.launch"/>

<node pkg="nodelet" type="nodelet" name="openni_manager" output="screen" respawn="true" args="manager"/>

<node pkg="nodelet" type="nodelet" name="pointcloud_throttle" args="load pointcloud_to_laserscan/CloudThrottle openni_manager"> <remap from="cloud_in" to="/camera/depth/points"/> <remap from="cloud_out" to="cloud_throttled"/> </node>

<node pkg="nodelet" type="nodelet" name="kinect_laser" args="load pointcloud_to_laserscan/CloudToScan openni_manager"> <remap from="cloud" to="cloud_throttled"/> </node> </launch>

1) After launch the file I open rviz , I set the fixed name to /openni_depth_frame and add a Laser Scan Display.

I followed this tutorial http://answers.ros.org/question/10606/problem-launching-pointcloud-to-laserscan/, and it says that I should see the /scan topic, but I am not able to see it.

How can I solve this?
