2014-09-27 05:33:56 -0600	commented answer	Recieve last Message on topic after subscription so the short answer to my problem is: ROS/rviz does not Cache Messages in Topics, so if i did not recieve a message in the first place, I will never recieve it?
2014-09-27 03:53:09 -0600	commented answer	Recieve last Message on topic after subscription I cannot use the standard plugins for all of my data, so i have written my own. And when I subscribe to a topic, then I want to have the last message on any topic - topics that i was not subscribed to, when this message came.

2014-09-26 16:46:52 -0600	commented answer	Recieve last Message on topic after subscription I start a replay with Rosbag (~50 recorded Topics), I start rviz, I recognize an error so i stop rosbag, then I want to evaluate the Data in rviz - without unpausing rosbag!
2014-09-26 15:24:55 -0600	commented answer	Recieve last Message on topic after subscription I have around 50 Topics, all of them are activly sent - so this will not work. So ROS does not have a standard way to do this?
