ccny_rgbd with vo+mapping rosservice call error

edit

Hello Dryanovski and fellow campaigners,

I am using ROS Groovy on an i3 laptop and ATI 6770m. I use your ccny package. Nearly everything works fine. I can start all launch files an see the rgbd screen (Topic: /rgbd/cloud) in rviz. Just one problem: I want to see the whole map in rviz, but it disappears. I think i must call the service rosservice call /publish_keyframes ".*" to publish all keyframes an set the delay time unequal zero. But i get just the error message after the call:

ERROR: service [/publish_keyframes] responded with an error:

nothing else :( In rviz i can set the topic to "keyframes", but no pointcloud!

I tried different detector types and change their params...no effect...

Thanks for your help,

Regards,

rossi
