Hello ! I'm trying to use the ExtFile product to upload files into the filesystem of the machine running Zope. I previously used manage_addFile to upload files (from a web page, not the manager) into the ZODB like this: context.manage_addProduct['OFSP'].manage_addFile(id=<>, title=<>, file=<> ) and now I would like to do something equivalent with manage_addExtFile; however, I constantly receive a key error Error Type: KeyError Error Value: standard_html_header It seems that it's not any of "my" dtml-vars, but rather my incorrect use of the ExtFile object, and being very new at this, I'm not making much out of reading the code. Could you please give me a hint on how can be a file uploaded from a web page with the ExtFile object ? Thank you ! Andrei Cenja, Bucharest, Romania.
