However the most problems I have had, are with poorly thought out or poorly documented object hierarchies, so that it is not obvious or clear where and when you should override methods, try "manage_afterClone" some time, and I know this isn't an acquisition problem, or overriding some of the default behaviour for FTP methods. The lack of documented approach is far worse than the enforced acquisition, IMHO ;-) If how these things work and how to use them, was well documented , then strangeness with acquisition wouldn't be so strange, ie it would be documented and you could get your head around it. (I think we will be in a much better position with Zope 3) Also if it doesn't work the way it is documented you could call it a bug, whereas the current situation is hmm is this how it work or is it a bug, or am I missing something ;-) Rgds Tim > Imagine if you couldnt write a C++ class without including operator > overloading functions......
