Scene visualization won't work on rviz plugin after some joint trajectory execution

[Kentaro Wada]

I've tried below code with moveit_commander, with this launch file.

The scene on rviz plugin appears before the trajectory execution with move(), but won't appear after the execution.
The scene object message on /collision_object comes, but the object won't visualized by the rviz plugin (moveit_motion_planning_rviz_plugin).

Anyone who are familiar with this problem?

(movie: scene at z=0 appears but z=-0.1 won't appear)

Hm. For me your example works.
Did you tried a larger final sleep() to give python time to process the calls before exiting?
