How to resume a task after canceled a task

[mxpfeng]

When I use actionlib in move base, I send cancel task topics. After a period of time, want to resume the task.What I did was resend the same target point.But the program did not respond.If I send a new target point, the program executes normally.How to solve it?
Thank you very much

ROS 1 is end-of-life (EOL) as of today, May 31st 2025. I am archiving this repository because:

• it only supports ROS 1
• it isn't needed anymore in ROS 2

If you still rely on ROS 1, read this page to learn about your options.
