[Zope] mapply & Z SQL Method

Hi.

I got a very weird problem with cduncan's mapply hint:

In a python product method i do following:

source_ = self.aq_acquire(self.source)
data = mapply(source_, self.REQUEST.args, self.REQUEST,
                  call_object,1,
                  missing_name,
                  dont_publish_class,
                  self.REQUEST, bind=1)

Where data most of the time contains the result of the method, in the case of 
ZSQLMethod objects, this will be a result instance.

Now the __call__ method of DA (defined in Shared.DC.ZRDB.DA) is defined as follows:

   def __call__(self, REQUEST=None, __ick__=None, src__=0, test__=0, **kw):
        """Call the database method ..."""

And src__ gets sometimes set to ZServerHTTPResponse('') which evaluates to a true
value and will return the source of the method instead of calling it. :/

Now i don't know how this happens, this actually doesn't look to be intended, as
src__ is expected to be 0 or 1, but definitely not a Response object.

Hints or solutions?

Thanks

Christian
