[Opensource] IllegalArgumentException calling ConfigManager.getMapping

[Michael Rimov]

Javier,

Because people were not specifying the initial states in their controllers, 
I was sometimes coming up with REALLY weird bugs when I didn't specify a 
'state' parameter.  So now if you specify

this.setInitialState(<whatever state name>);

in your controller's constructor, you'll be ok.

HTH!
                                         -Mike
