Re: [Zope] How to see if two objects are the same (minor fix)

I want to see if an object is the one aqcuired from the root, but I'm hitting walls.
<dtml-var "PARENTS[-1].myObject"> <dtml-var "myObject"> <dtml-var "PARENTS[-1].myObject is myObject">
This returns the following when in the root folder context:
<TinyTable instance at 8684ad8> <TinyTable instance at 8684ad8> 0
It returns the following in a folder where there is another myObject:
<TinyTable instance at 8684ad8> <TinyTable instance at 86709f8> 0
What am I missing in the comparison?
You are seeing the result of a (mis)feature of acquisition: the objects you are comparing are actually AcquisitionImplicitWrappers around the real 'myObject'; because the two wrappers are different, and because the underlying object doesn't define a custom '__cmp__()' method, the two wrappers are compared for identity (which is bogus). I recently fixed this in response to a Collector issue: http://classic.zope.org:8080/Collector/1650/view You can get the patch from that page, or just wait for Zope 2.3 (RSN, I'm sure).
