Header Assignment Ros not working for Header.FrameId

Hi,

I am using the example given by matlab for update header field in ros message.

open_system('rosHeaderAssignmentBlockExampleModel.slx').

THis example works fine.

I wanted to publish the frame id : lidar_link in a topic /my_topic, so I added a publisher with same message type(sensor_msgs/LaserScan).

The publisher bloc is connected to Bus assignment where i selected Header.FrameID, the bus assignment input is connected to Header Assignment block.

All other selection (Header.Stamp), rangeMin,Range max ...works fine but Header.FrameId not working. it display frame_id: ''.

Any adea to how to resolve that ?

Thanks by advance.

problem resolved by selecting Header.Frameid_SL_info too in Bus assignment and Header assignment bloc.
