This is not the case. Quite to the contrary, ZPublisher (its "mapply") cannot
handle "*args" and "**kw" argument definitions.
For some unknown reason, "mapply" seems to get the method signature wrong and thinks it has to call the object with 4 arguments. Apparently, your change did not modify what "mapply" sees and your object now accepts (almost) arbitrary many arguments.
Well, the additional parameters I added aren't used in the function itself, there is no other side effect than to stop this exception. It would of course be better to pass the 'correct' parameters if at all possible.
"mapply" is often tricked out by a "func_code" definition. Maybe, your class has such an attribute and it does not match the "__call__" signature?
Hmmm - this isn't MY class, it's HelpSys::STXTopic. I can't see any func_code definition in the HelpSys source. STXTopic's __call__ function is declared as __call__(self, REQUEST=None) which looks quite fine to me.
Therefore mapply is getting it wrong and passing too many parameters into this call. How do I discover what mapply is passing???
