Exclude topic from namespace

edit

Hello,

I have a Turtlebot running the navigation stack and a workstation that runs the corresponding map-server.

The amcl node is launched in a namespace so that all published and subscribed topics get prefixed with that namespace. So amcl is subscribing to /namespace/map instead of just /map.

Now I want to exclude the map topic from the namespace so that amcl subscribes to /map again but all other topics should still be prefixed. I tried to remap it from "map" to "/map" but that didnt't change anything.

Thanks for your help.
