Setting projector pose vs. enclosing link pose?

In gazebo 1.9.2 I see behavior where setting the pose of a projector produces glitchy results (see left of image below), whereas setting the pose of the link enclosing the projector looks as expected on the right:

SDF source file

I observed a similar glitch using projectors launched from ROS Hydro urdf/xacro files ( http://answers.ros.org/question/11872... ), I need to experiment to see if I can get it working there by only manipulating the link pose and avoid using the projector pose.

I'm using the latest gazebo (gazebo-current ubuntu package), and the projector seems to work okay.

Could you try the latest gazebo out?

I've added system details above, I don't have a gazebo-current, though there are nightly and prerelease options provided by packages.ros.org. http://gazebosim.org/wiki/Install/Gazebo_and_ROS suggests I need to build from source to get gazebo-current.

gazebo-current (and even ros-gazebo-pkgs-current) is available as a package in the packages.osrfoundation.org repository. You can install it as a package, but be sure of using a catkin workspace with your ROS packages so they get built from source on top of the gazebo-current package. You can not use ROS repository gazebo related packages with gazebo-current (ABI incompatible).

It took me a while but I followed http://gazebosim.org/wiki/2.0/install ( some background details are on http://binarymillenium.com/2014/02/installing-full-desktop-ros-hydro-from.html ), I see the same faulty behavior. Despite running hg up gazebo_2.0 I appear to have version 2.2.1 when I run what I've built. Is there something newer I should try?

I may not have been clear in the post, but the sdf file check in earlier was the working one, the one I've just pushed shows the faulty behavior.
