[Zope] redirects & POST

[Dario Lopez-Kästen]

Is there a way, or more accurately, has anyone done something like this w/o
making the form call it-self?

I am asking because I am currently in a bit of a nightmare having to
maintain other peoples code that uses forms that call themselves
recursively, and I am trying to develop some coding guidelines for my
projects that will ban the usage of forms that call themselves.

I know, I know, they can be damned handy at times but, as I said, the
maintenance burden can be a pretty masive, especially when you try to
debug/modify them.

Or is there no other way?

Thanks,
