GREAT! (hi massimo, it's fantastic to see this happening).

looks _great_. absolutely delighted to see it.
first thing i'd recommend doing is to test the jsonrpc service, stand-
alone - nothing to do with pyjamas:
1) http://lkcl.net/jsonrpclib.tar.gz (it's a copy of someone else's
stand-alone jsonrpc client, really good code, really useful, can't
remember who wrote it! many apologies to the original author! )
2) create a quick test testweb2pyjsonservice.py, and run it as
python ./testweb2pyjsonservice.py:
import jsonrpclib
s = jsonrpclib.ServerProxy("http://localhost:8000/todoApp/service/";) #
check this!
# show list of tasks
tasks = s.get_tasks()
print tasks
# add one
tasks = s.add_task("debug pyjamas webpy service")
print tasks
# how do i get the task id of the one just added? err...
task_id = 1
# bug in design of todo service - how do i identify the task just
added?
tasks = s.delete_task(task_id)
print tasks
so immediately you can see there's a little bit of work needed.
controllers/default.py's add_task() should be something like this:
@pyjamas
def add_task(request,taskFromJson):
t = db.todo.insert(task= taskFromJson)
return t.id # TODO: look up web2py db api, check this is right.
also, from a code-style perspective, i would call that @jsonservice
not @pyjamas, because what's actually being done here - so far - has
absolutely nothing to do with pyjamas, and everything to do with
jsonrpc.
so i'd rename the file models/pyjamas.py to models/jsonrpc.py and put
"jsonservice = JSONRPCService()" instead.
otherwise people will think pyjamas equals jsonrpc and get very
confused.
_then_, once the above test code works as expected, _then_ you can
move on to compiling the front-end pyjamas (which unfortunately looks
like it got corrupted in the cut-paste).
