I've noticed another strange behaviour with the Acquisition module in Zope 2.9 that might give us some clues as to why refreshing doesn't work.
Imagine some code that looks like this:: from Acquisition import aq_parent class MyProduct(Folder): def index_html(self): print type(aq_parent) is None return "Hello World!" The first time I run this, it prints "False" to stdout because ac_parent is of course a function. BUT, if I refresh the product (no change made to the source) and run this index_html() again it instead prints "True" because ac_parent has become None. Isn't that odd? Again, this is easily reproducable with http://www.peterbe.com/zope/2.9-refresh-reproduction/MyProduct.tgz Any idea anyone?
