I'm trying to create my first Python product in Zope, and I'm running into a strange problem. Basically I have two manage_options tabs (Edit and View). The Edit tab is a simple form to change the title property (I'm starting out very simple). The problem is that the Edit tab disappears after I submit the changes, and then reappears if I go back to folder the object is contained in and select the object again. To eliminate newbie mistakes as the cause of the problem, I uploaded the Addressit Product from the Zope Bible (the earliest version from Chapter 7, again to keep it simple). The problem occurs with that product, too. I'm running Zope 2.5.1 with Python 2.1.3 on Windows 2000 (binary distribution). I also have a Mac (OS X 10.1.5) with the same versions of Zope and Python, and both the Addressit Product and my own product work normally there (the Edit tab doesn't disappear). So I suspect some problem with the Windows binary distribution. Has anyone else seen this problem? Should I try getting a different distribution? Or is it safe for me to ignore the problem?
