Hi Dieter. Many thanks for your reply. The place in my workflow that it
failed was opening the image.
IOError: cannot identify image file
for image_data in image_data_list:
# Get original image data into string object
original_file = StringIO(str(image_obj.data))
image_size_px = image_data['size']
# Create an image instance
error here --> image = PIL.Image.open(original_file)
This had me puzzled since my workflow works in all other cases in the
portal including cutting an image from one folder and pasting into the
folder the workflow acts on (just not FTP case). So I wrote a very
simple workflow script that will only cut and paste an image back in
same folder to see what would happen:
# Get the object and its id
image_obj = state_change.object
id = image_obj.getId()
# This is the folder we are starting from
upload_dir = image_obj.aq_parent
# Do cut and paste
objs = upload_dir.manage_cutObjects([id])
upload_dir.manage_pasteObjects(objs)
return
I discovered that it does not appear possible to have a workflow act on
content immediately after being FTP'd to a site without generating the
'FTP 426 Error creating file' error. If I FTP an image to the folder
as Manager with copy or move permission, it will trigger 426 Error
creating file and the following traceback. The workflow will work for
regular operations within the portal, just not FTP.
* Module OFS.CopySupport, line 92, in manage_cutObjects

<TD VALIGN="TOP"> <BR><BR> <CENTER> The action against the
<em>A084.JPG</em> object could not be carried out. One of the following
constraints caused the problem: <br><br>The object does not support

VALIGN="TOP"> <CENTER> <INPUT TYPE="SUBMIT" VALUE=" Ok "> </CENTER>
</TD> </TR> </TABLE> </FORM> </BODY></HTML>
The body of the image appears in my traceback as well
My folders work fine with FTP without the workflow - no errors. Only
generates errors when workflow is attached to type it acts on and then
426 error appears.

David

but when I FTP
my images to this directory it fails giving me a 426 Error creating

Look at your "error_log" object to find out the real reason
(and get the traceback).
