I am using single scan sensor_msgs/LaserScan message provided in laser.bag, and I try to use the Laser Scan Assembler to form a bigger point cloud, by it fails in rviz (seems not bring in sensor_msgs/PointCloud message). what are the possible reasons?

The issue is deals with the message type. If you open it as a PointCloud2 in RVIZ, it should work.
I find that the original code exits a bug: in the construction function, the code of the example in the link I list before doesn't include initialization code of ros::nodehandle, I add this code and it works.

Ok, finally, I find I use a wrong simulation time, as the clock section said, we should set /use_sim_time to true before we run the service calling node.
