[Zope] filefield value when empty

Hi everyone, I figured this one out for myself and thought maybe someone would be interested in the answer. I found that even when no value is added to the field using the browse button, (and even despite defining a default value) the REQUEST shows a 'FileUpload instance object'. Therefore you have to check that the filename attribute of this fileupload instance object is empty: if getattr(file, 'filename')!="": do something ........ Hope this can be helpful to someone, Marie
