declarePublic was never meant to be called without any names, hence
the signature change. Calling it without names is a bug in
JMZPTMacros. Most likely, the author meant to protect the method right
below that line.

To illustrate, the code probably looks something like:

  def someMethod(self, REQUEST):

You put the name of that method in a string:


It could also be that the author assumed that not putting in a method
name meant that *all* methods on the class would be public. In that
case, you'll need to use declareObjectPublic() instead.
