[Catalyst] chained actions, knowing if current action is an endpoint or not

If I understood your problem correctly, here's an example of what I'm
doing to handle things like /store/1234 /store/1234/comments
/store/1234/map

in e.g MyApp::Controller::Store:

# Common thing to for each "store"
sub store : Chained('') : CaptureArgs(1) : PathPart('store')

# Will handle /store/1234 -- That's the endpoint I think you are talking
about
sub index : Chained('store') : Args(0) : PathPart('')

# Will handle /store/1234/comments
sub comments : Chained('store') : Args(0) : PathPart('comments')

# Will handle /store/1234/map
sub map : Chained('store') : Args(0) : PathPart('map')
