roscpp and latched topics

Hi there, I have the following problem.

One of my node just parses a file and stream reference trajectories as Path/Markers topics. These trajectories are almost never updated. Therefore I would like to use latched topics to avoid updating for nothing.

Therefore I have the following setup:

  1. parse data, create publishers with latching enabled
  2. publish once in each topic
  3. spin forever

...and if I use rostopic to retrieve the topics data, nothing comes from the node.

Am I missing something?
