[ros-users] Error in Publishing the composite messages

Hi,

I'm trying to implement the composite message of string, image and
numbers as follows.

<my_msgs.msg>
string name
sensor_msgs/Image left_image
sensor_msgs/Image right_image
int32 size
int32 maximum

When I ran the rostopic to generate the my_msgs, there is an errors as
the follows.

$rostopic pub -r 1 /my_test test_msgs/my_msgs BlockMatch /BB2/left_rgb
/BB2/right_rgb 11 256
ERROR: No key named [/BB2/left_rgb]

Args are: [name left_image.header.seq left_image.header.stamp
left_image.header.frame_id left_image.height left_image.width
left_image.encoding left_image.is_bigendian left_image.step
left_image.data right_image.header.seq right_image.header.stamp
right_image.header.frame_id right_image.height right_image.width
right_image.encoding right_image.is_bigendian right_image.step
right_image.data size maximum]

However, when I checked the rostopic list, /BB2/left_rgb and
/BB2/right_rgb was publishing properly and it was double checked by
image_view. The environment is boxturtle 1.0.5 on the Ubuntu 9.10

Any comment would be highly appreciated.

Best,
Soonhac
