[Catalyst] A point of confusion/frustration on chained actions

As far as I understand from your message, the solution is quite easy. You're
problem is due to the fact that Catalyst forces you to define end-points and
mid-points for your chain. Sometimes you need to have an action which can
double both as a mid-point and as an end-point, as with your
/tutorial/*/comment/* and /tutorial/*/comment/*/replies example. In this
case all you have to do is create the comment action as a mid point, and
then create another action with a different name, but the same PathPart
(e.g. comment) only this time as an end-point, and all this action needs to
do is forward or detach to the original action (also passing any parameters
it needs).

I am trying to sort out some interdependent chains and I'm having trouble
figuring out why the urls I'm trying to build aren't working out.
I have a site where the primary objects of interest are flash-based
tutorials. Each tutorial can have comments, and each comment can have
replies. I'm using jQuery to manipulate comments in a REST fashion, and I'm
aiming for a url map like this:
/tutorials # GET a list of tutorials, or POST a new
tutorial
/tutorials/* # GET/POST/DELETE a specific tutorial
/tutorials/*/comments # GET the comments for a tutorial, or
POST a new comment
/tutorials/*/comments/* # GET/POST/DELETE a specific comment
/tutorials/*/comments/*/replies # GET the replies for a comment, or POST
a new reply
/tutorials/*/comments/*/replies/* # GET/POST/DELETE a specific reply
But the best I've been able to come up with is this:
/tutorials
^tutorials/(\d+)$
/tutorial/*/comments
/tutorial/*/comment/*/replies
/tutorial/*/comment/*/reply/*
missing: /tutorial/*/comment (what would I call it? /tutorial/*/cmt ?)
Essentially I'm hitting an issue with is due to the (seeming?) impossibility
of matching a chained set of actions at multiple url depths. Is it possible
to build the url structure I'm looking for above using chained actions?
thanks,
Stephen
