[Zope] Re: mapply & Z SQL Method | mapply bug

[Christian Theune]

ok. I am getting on that, what i currently see, is that the mapply() function
seems to misbehave significantly ...

The sqlmethod gets callen with the parameter src=RESPONSE and that must happen
somewhere in the mapply() function, which i can't really debug as it is very
hard to read ... any hints appreciated ...

Greetings

Christian
