Re: Re: buildZipArchive

Now I write zipfile "by hand" to temp dir in py script:

	context.localfs_write(tempfolder + '/' + filename.rsplit('.')[0] + '.zip', exportfile, mode='b')

and read it back to zms:

            <dtml-let zipFile="localfs_read(tempfolder + '/' + filename.rsplit('.')[0] + '.zip', mode='b', REQUEST=None)">
                <dtml-call "setObjProperty('image_file',zipFile,lang)">
            </dtml-let>

but this gives me:

Exception Type	TypeError
Exception Value	coercing to Unicode: need string or buffer, filestream_iterator found
Traceback (innermost last):

TypeError: coercing to Unicode: need string or buffer, filestream_iterator found

Any ideas for that?
