I was only 1/2 watching anything. The other 1/2 was making sure all 3 rooms
had
something to watch :)

Those all seem to bind to self.something, which I don't think helps with the
cdxml. maybe Demo needs a cdxml example, with a very basic (like 1 label one
textbox) cdxml and show how to bind controls in it to some other object.

That seemed like the obvious one. figured if it didn't have it, the rest
wouldn't either.
More on UI when I get the BO working.
I made a BO prop:
class uLoopBO(dabo.biz.dBizobj):
def _getHost(self):
return self.Host
def _setHost(self, val):
self.Host=val
Host = property(_getHost, _setHost, None,
_("""Hostname of sql database server"""))
def initProperties(self):
self.host = 'localhost'
I see to instantiate one of these, I need to create the connection first?
class dBizobj(dObject):
def __init__(self, conn, properties=None, *args, **kwargs):
cf = self._cursorFactory = conn
I was going to have a BO method create the connection once the user had entered
in the parameters. might even write a unit test for this part. so how do I get
the BO created?
