Hi Inside a Python product, I tried to access another object this way: self.restrictedTraverse('/Folder/Object') This worked fine until this evening, when I got an error 'Object not callable' The error was on Traversable.py, function unrestrictedTraverse, line 166 (Zope 2.4.3 (binary release, python 2.1, win32-x86), python 2.1.0, win32) self=self.getPhysicalRoot() When I printed type(self.getPhysicalRoot), I got: <Special Object Used to Force Acquisition>' (what's that???) This was for a while, I tried several ways to circumvent this problem, and I was happy when I found something that worked fine. But when I tried the original code again to post here, it worked fine (as usual!) and now type(self.getPhysicalRoot)=type <'Python Method'> (as should be, I guess) I swear I didnt change anything but a few lines on my product!!! Nor even restarted Zope, just refreshed my product. And it's my own local install, so nobody else was working at the same server. So I don't understand why it began to fail, and why it suddenly was working OK again... Gabriel Genellina Softlab SRL
