This certainly simplifies things, but there are still a couple of problems. Firstly, the user gets no warning if he checks multiple "is billing address" boxes on the inline forms and it doesn't seem to be totally predictable which of the addresses' save methods will be called, and then which will be called last, and therefore which will end up being marked as the billing address. Any suggestions? Or is there a way to make them show up as radio buttons? Next, there's nothing to stop no addresses being given, or no addresses being marked as the billing address. I guess I could put the monkey patch back on so I can force the first address to be billing if none is. Is that the best solution to this problem? But even then the problem of how to stop a customer being created if no addresses are given remains.
