[Zope-dev] unpickleable error

[auto44082@hushmail.com]

I posted the whole problem to the list earlier but had no takers. So I'm 
trying to break it down and figure it out that way.

Does anyone know what causes unpickleable errors? I've got a dtml-method 
which gets called from another dtml-method/form where a user enter's data. 
(namely a file to upload, and a check box indicating whether or not they 
want the file converted). All my dtml method does is change data in a few 
already-defined properties. I've commented out my dtml statements and put 
them back in one at a time, to see if I can isolate the one which is causing 
the error. Here it  is:

<dtml-call "manage_changeProperties(upload_file=REQUEST['new_file'],)">

"new_file" is the name of an input field of type "file" in the form the 
dtml method containing the line above was called from. If i replace the 
line above with the following:

<dtml-call "manage_changeProperties(upload_file='This is a test',)">

things work fine. However, as it is, I get an Unpickleable Error (see traceback 
below). I'm not sure what difference it makes, but the file I'm supposedly 
uploading is a MSWord Document.

Does anyone have ideas? Thanks!
