I've just installed Zope, and as an initial test I entered the various files from the "Job Board" example given in a "Technical Introduction to Object Publishing with Zope". However, when I try to "Add External Method", I get the error "Error Type: AttributeError Error Value: func_defaults" with no line number given. I really can't see what the error is. I haven't really tried staring at the locations of the traceback in the Zope functions, but should this really be necessary?! So this brings up the general question: when you're writing new External Methods, what development methodology do you use? Unless you're perfect (and I'm not one of these) and never make any errors, you certainly need something which will get the methods, debugged, etc. Also, I also tried, the alternative suggested in the "Zope Content Managers Guide" of putting the external methods in the Extensions subdirectory of a Product (I made a new product called "Test"), but even though I gave Test.JobBoard as the name of the module file, it couldn't be found.
