[cells-devel] baby steps

[Ken Tilton]

The attached works a tiny little bit.

Running hunch, starting the server with the snippet at the top of 
example.lisp, running (reload), and then navigating to 8000/apropos I 
see three symbols matching the initial value of "md-slot-v".

Deleting the "v" and then tabbing I see eight values matching 
"md-slot-". This required especially telling the handler creater not to 
expect "/apropos" as the prefix to subsequent messages (in fact ( i just 
defaulted if the name did not match apropos.

Oh, you will also see hijinx where I store nodes by name as well as by 
ID, because I got back (("term" . "md-slot-")...) not (("i1234" . etc)) 
even though I see openair.js returns the id. Go figger.

Oh. I may have really screwed up. At one point it seemed only the 
changed field (the search term) was being sent, suddenly I see the "pkg" 
as well, perhaps meaning there is no need to keep a copy of the 
client-side-data as you will see I am maintaining. Obviously I have no 
idea what is going on, perhaps I am seeing "pkg" only as a fluke 
behavior of pop-up menus (maybe if they are uninitialized they choose 
the first value and then that looks like a change to be transmitted?) I 
am clueless. If browsers always send all non-nil attributes with every 
request (a) that sounds like a waste and (b) we can lose the 
client-side-data hash table. Hopefully (a) is not the case (and anyway I 
thought /we/ were deciding what to send...hmmm, I am starting to like my 
theory about pop-up menus).

whew! learning curves are exhausting, but fun. This seems to be working. 
I would love to feature this at eclm 2008 beacuse it shows how Cells 
interconnect values, how Cells facilitate the driving of an alien 
framework by a Lisp framework, and finally because it is Web 2.0, 
something folks might actually be interested in.

Hang on. I just edited in some "<-kt" prefixed comments, and am 
attaching again example.lisp. I decided to retest and, whoa, a problem 
resurfaced: the whole thing simply stops working. I got stuck on this 
earlier and was just recompiling here and there with new debug 
statements and it started working again. That suggests, btw, that there 
is a defparameter or something that gets reset by the file being 
recompiled and reloaded (but I tried a full recompile and that did not 
help). Anyway, I am sure it is something stupid, and it is too late for 
me to stare at.
