James,
I've attached some code I use for having an agent create another agent.
This is my StarterAgent that creates a set of other agents. You can
obviously ignore the stuff about the XML usage in the setup() method.
The creation of agents is in the CreateAgentsBehavior inner class. The
code works for JADE 2.5, so I don't know about 2.6. Also, it doesn't use
the ContentManager, which I believe is the recommended way of putting
together messages - just haven't refactored yet!
