On_Pause concurrency state [closed]

edit

Hello everyone, I'm working with FlexBE, I've put on place a working behavior that can move the turtlebot frome position A to position B , Now I'm trying to do more complexe mouvement... im using TEB local planner, so whenever I try to pause the ' follow_path state' everything is stopped ( even the turtelbot since I'm publishing a Zero Twist Message) and whenever I resume , the robot keeps following the path .

The problem occurs when the follow_path_state is included into 'a concurrency container' it doesn't work , it first continues following the path then at the end it pauses everything ! Is there any solution ? Thank you,
