# Issue with message_filter.h dashing/crystal release

The add method in dashing release use 3 parameters for MEvent , which has header as an argument. Where as message_event class do not have any constructor which has header as an argument. Can some one look into it and fix it or clarify me on this if i missed something.

void add(const MConstPtr & message)
{
using builtin_interfaces::msg::Time;
