Hello, I tried to set the End Datetime for an datetime Formulator object to the current time. I uses TALES and started with python: form.DateTime() This failed with Error Type: AttributeError Error Value: DateTime Now I created a Python script named 'jetzt' which just does return DateTime() and alternatively I tried return str(DateTime()) moreover I tried several different formats. The error.log of Test method of the Formulator object was always like: Traceback (innermost last): Module ZPublisher.Publish, line 98, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module Shared.DC.Scripts.Bindings, line 252, in __call__ Module Shared.DC.Scripts.Bindings, line 283, in _bindAndExec Module App.special_dtml, line 174, in _exec Module DocumentTemplate.DT_Util, line 201, in eval - __traceback_info__: render Module <string>, line 0, in ?
