-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I have a product working fine on a computer with Zope 2.7.0rc2 and Python 2.3. I copy the dirdectory of the product on another computer with Zope 2.7.2 and Python 2.3.3. I create an instance of my product, and when I try to access it (from the manage part or the normal part) I have the following error: * Module ZPublisher.Publish, line 180, in publish_module_standard * Module ZPublisher.Publish, line 131, in publish * Module Zope.App.startup, line 204, in zpublisher_exception_hook * Module ZPublisher.Publish, line 101, in publish * Module ZPublisher.mapply, line 88, in mapply * Module ZPublisher.Publish, line 39, in call_object * Module Shared.DC.Scripts.Bindings, line 306, in __call__ * Module Shared.DC.Scripts.Bindings, line 343, in _bindAndExec * Module App.special_dtml, line 175, in _exec * Module Shared.DC.Scripts.Bindings, line 320, in __render_with_namespace__ * Module Shared.DC.Scripts.Bindings, line 343, in _bindAndExec * Module App.special_dtml, line 175, in _exec * Module DocumentTemplate.DT_Util, line 198, in eval __traceback_info__: RESPONSE * Module <string>, line 0, in ? AttributeError: 'NoneType' object has no attribute 'setHeader' (Also, an error occurred while attempting to render the standard error message.) The file generating this error is a simple one (see attachment). An idea of what is going wrong? - -- Prof. Pascal Francq Université libre de Bruxelles CAD/CAM Department Avenue F.D.
