Revision history [back]

I am creating another SimpleActionClient local variable in a member function. The Class already has a member. So, I send the goal using the local variable, where as I try to cancel it using the Class variable. It can never work. Now, I am able to Pre-empt the goal. Sorry for the trouble. Problem solved.
