Errot Type: NameError Error Value: folder1

How to manage this problem ?

FR.

===== CODE ===== def testFolder(self): self=self.this() sub1=self.folder1 exec "object2create = 'folder11'" try: if sub1.object2create: return 'Object exists' except AttributeError: sub1.manage_addFolder(object2create) return 'Object created' Are you sure, you get the "NameError" inside your external method?

I hope, you are not, because the method cannot raise a (NameError,folder1). Anyway, if your problem is in Python code, the traceback contains precise line number information for the problem. In order to test, whether an object O can access another object o, you can use: "hasattr(O,'o')". In your example: if hasattr(self,'folder1'): return 'Object exists' This will not test, that 'folder1' is contained in "self" but that a 'folder1' is accessible (acquired) in "self". In order to test for direct containment, you would use "self.aq_base" instead of "self". Dieter
