[Zope] Annoying ambiguous name

I define a method like this: ListIssues = PageTemplateFile('zpt/ListIssues', globals(), __name__='ListIssues') Then I want to make a shortcut to that method like this: listissues = ListIssues But then I get that annoying message:: 2002-05-04T16:04:13 PROBLEM(100) Init Ambiguous name for method of Products.IssueTrackerProduct.IssueTracker.IssueTracker: "ListIssues" != "listissues" How do I get this right?? I also tried (outside the class): IssueTracker.__dict__['listissues'] = IssueTracker.ListIssues but still the same old error. Anybody knows how to solve this? Peter
