[Zope-dev] Strange local(?) bug in uploading files

[Peter Arvidsson]

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):

I tried to look in the python-files for manage_addFile but I didnt see
anything wrong there (however I am a python newbie :) Why do I get this
error in 2.2? 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?
