[Zope-dev] Problems adding many objects
Hi, I've created a script that imports XML into the ZODB, using regular TTW methods - and all is fine, except for when I import large files, with many objects. After about 288 objects, the import fails when the method that adds an object in the ZODB returns None, instead of the object it added. From what I can tell, the added object is not None before it is returned, but the name object, set via the expression object = self.manage_add_issue(...) is None. So it looks like somewhere between 'return issue_' in manage_add_issue and the expression above, the object is lost. Any ideas what could be happening here?
