Overall it is not a bad way to proceed. The only place I might direct you some place different is where you save to the local drive if the server is unavailable.
For this part, I would suggest you take a look at a concept called 'Local Shared Objects' Without knowing all of the details of your setup, I would suggest that saving an XML file to their system without the help of a server is going to be tricky if not impossible. --Mike --- In flexcoders@yahoogroups.com, "advantexllc" <[EMAIL PROTECTED]> wrote: > > I posted this on the Adobe web forum, but I think I'll have better > luck posting here. > > I am a newbie to flex... using flex 2 builder and cfmx 7.0.2.
