I have a major problem with uploading files. I am doing a form to upload PDF-files This is what it looks like (with only the relevant code): pdf_form: <form method="POST" action="pdf_method" enctype="multipart/form-data"> Title:<br> <input type="text" size="70" name="titlepdf:required"><br> PDF:<br> <input type="file" size="58" name="pdf:required"><br> <input type="submit" name="add" value="Next"><br> </form> pdf_method: <dtml-call "REQUEST.set('ts', ZopeTime())"> <dtml-call "REQUEST.set('pdfid',_.str(_.int(ts)))"> <dtml-call expr="manage_addFile(pdfid, file=pdf, title=titlepdf)"> When I run this code in 2.1.6 it almost works. The content_type is wrong but if you edit this property and set it to "application/pdf" it works. (This is another strange problem.. this should be set automaticlly. I doesnt work when I pass content_type='application/pdf' either.) However when I try to run this in Zope 2.2 i get the following error (with traceback): Error Type: AttributeError Error Value: seek Traceback (innermost last): File /usr/local/new.test.version.of.zope.DO.NOT.REMOVE/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/new.test.version.of.zope.DO.NOT.REMOVE/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/new.test.version.of.zope.DO.NOT.REMOVE/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: ElementWithAttributes) File /usr/local/new.test.version.of.zope.DO.NOT.REMOVE/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/new.test.version.of.zope.DO.NOT.REMOVE/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: pdf_method) File /usr/local/new.test.version.of.zope.DO.NOT.REMOVE/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: pdf_method) File /usr/local/new.test.version.of.zope.DO.NOT.REMOVE/lib/python/OFS/DTMLMethod.py, line 167, in __call__ (Object: pdf_method) File /usr/local/new.test.version.of.zope.DO.NOT.REMOVE/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__ (Object: pdf_method) File /usr/local/zope/lib/python/DocumentTemplate/DT_Util.py, line 342, in eval (Object: manage_addFile(pdfid, file=pdf, title=titlepdf)) (Info: pdf) File <string>, line 0, in ?

I have tried everything and consulted the irc-channel but noone could help me. Is this a bug in 2.2 or am I doing something wrong?
