<trajectory_msgs::JointTrajectory> Question

edit

Hello all,

How do I declare positions in a trajectory_msgs::JointTrajectory variable? I am trying to input a IK service reply into a JointTrajectory positions:

trajectory_msgs::JointTrajectory l_traj_goal;

for(unsigned int i=0; i < l_gpik_res.solution.joint_state.name.size(); i ++)
{
l_traj_goal.points.positions[i] = l_gpik_res.solution.joint_state.position[i];          
}

but I get a compiling error:

error: ‘trajectory_msgs::JointTrajectory_<std::allocator<void> >::_points_type’ has no member named ‘positions’

Does anyone know what's going on here? I think this is a small coding error but my C++ skills are lacking

Kind Regards, Martin
