I am trying to catch a 'BadRequest' exception in the following python script excerpt: for item in itemList: try: context.afolder.manage_delObjects([item]) except BadRequest: continue The rationale behind this is that itemList may contain entries that no longer exist in 'afolder', but I would like to delete whatever does exist. 'BadRequest' is not a python built-in exception, so whenever the above except clause is invoked it actually causes another error: 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 OFS.DTMLMethod, line 126, in __call__ Module DocumentTemplate.DT_String, line 474, in __call__ Module DocumentTemplate.DT_In, line 705, in renderwob Module DocumentTemplate.DT_Util, line 201, in eval - __traceback_info__: _ Module <string>, line 2, in f Module Shared.DC.Scripts.Bindings, line 252, in __call__ Module Shared.DC.Scripts.Bindings, line 283, in _bindAndExec Module Products.PythonScripts.PythonScript, line 315, in _exec Module Script (Python), line 25, in subDeleteAd - <PythonScript at /fas/subDeleteAd> - Line 25 NameError: global name 'BadRequest' is not defined I can work around this problem by checking to see if the item exists in 'afolder' before I try to delete it, but I was curious as to how you go about trapping a 'BadRequest' error in a python script?
