Hi,
even as uncle of iw.fss, I have some pain to understand what's going
on. The AT type seems OK, but the traceback mentions ...
(<Products.Archetypes.Marshall.RFC822Marshaller instance at
0xd1473b0>, 'demarshall', <ATDocument at
/sara/data/probandendaten/testMedium.mzML>, {'mimetype': None,
'REQUEST': <FTPRequest,
URL=http://0.0.0.0:8140/Zope2/sara/data/probandendaten/testMedium.mzML/PUT
>,
'RESPONSE': FTPResponse(''), 'context': <ATDocument at
/sara/data/probandendaten/testMedium.mzML>, 'filename':
'testMedium.mzML'})
Seems that this occurs when the user uploads an ATDocument through FTP
or I'm reading something else ? In addition, the data is processed by
wicked and that's strange to me. Did you mark wicked awareness on your
content type () ? IMHO this makes no sense unless I'm missing
something in your schema that seems to be close close to an ATFIle.
Please provide me that package (SVN URL) and a test scenario.
Cheers

Anyone encountered the following error?
Plone 3.3 with a custom content-type using iw.fss for a FileField:
from zope.interface import implements, directlyProvides
from AccessControl import ClassSecurityInfo
from Products.Archetypes import atapi
from Products.ATContentTypes.content import base
from Products.ATContentTypes.content import schemata
from Products.Archetypes.public import PrimaryFieldMarshaller
from iw.fss.config import PROJECTNAME
from iw.fss.FileSystemStorage import FileSystemStorage
from wsi.sara import saraMessageFactory as _
from wsi.sara.interfaces import ImzML
from wsi.sara.config import PROJECTNAME
mzMLSchema = schemata.ATContentTypeSchema.copy() + atapi.Schema((
# -*- Your Archetypes field definitions here ... -*-
atapi.FileField(
'File',
# storage=atapi.AnnotationStorage(),
storage=FileSystemStorage(),
default_content_type = "application/octet_stream",
widget=atapi.FileWidget(
label=_(u"mzML file"),
description=_(u"raw mzML data"),
),
validators=('isNonEmptyFile'),
),
),
marshall=PrimaryFieldMarshaller(),
)
# Set storage on fields copied from ATContentTypeSchema, making sure
# they work well with the python bridge properties.
mzMLSchema['title'].storage = atapi.AnnotationStorage()
mzMLSchema['description'].storage = atapi.AnnotationStorage()
schemata.finalizeATCTSchema(mzMLSchema, moveDiscussion=False)
class mzML(base.ATCTContent):
"""mzML files"""
implements(ImzML)
meta_type = "mzML"
schema = mzMLSchema
title = atapi.ATFieldProperty('title')
description = atapi.ATFieldProperty('description')
# -*- Your ATSchema to Python Property Bridges Here ... -*-
File = atapi.ATFieldProperty('File')
atapi.registerType(mzML, PROJECTNAME)

SystemError: Negative size passed to
PyString_FromStringAndSize
The error within guess_encoding is triggered by this issue in Python
2.4:
http://bugs.python.org/issue7551
The more high-level issue is: is there something (stupid) in iw.fss
triggering
this issue? I could not find an obvious way for getting around this
problem.
Not using "marshall=PrimaryFieldMarshaller()," results in a different
error as described in this thread:
https://mail.zope.org/pipermail/zope/2009-December/175561.html
Also no idea why Archetype is calling setText() for a
BaseContent-derived type:
Module Products.Archetypes.Marshall, line 239, in demarshall
Module Products.ATContentTypes.content.document, line 176, in
setText
Thoughts?
Andreas
