[Zope] Strange behavior in folderish class

[Dylan Reinhardt]

It's tough to fill in the blanks, but here goes:

I'm assuming that myMethod is associated with index_html?  If not, what 
*are* you calling and how?

How is id generated?  Do you type it in your manage_addMyClass form or is 
it generated by some more clever means... something that persists 
information between instances, perhaps?  Might it be a combination of the two?

What if you copy & pasted instance B to be in the same container as A and call:

http://mysite/myClassInstaceB

What does that give you?

My first guess here would be that you goofed somehow and have derived id 
from something that's remained constant between instances... a class 
variable or an argument default, perhaps.  My second guess would be that 
you're not actually calling myMethod, but something else entirely.  A 
distant third would be that somehow you're not assigning instance B an id 
at all... that might cause id to be acquired from its parent.

Does any of this reveal any new information?
