I have Plone-2.5.5 installed with as a zeocluster. I created two sites, one ahs and one ahs_dev. Each one has a separate data.fs file in separate directories. Each site has identical products. I added a python script to the Extensions directory under client1, client2, and skel. I am able to add the script as an external method in the ahs site and it works. When I try to add the same script as an external method in the ahs_dev site, I get a 404 Error - object not found. Why can't I add the external method to the second site? I even tried renaming the script and I still cannot add an external method to the second site. What am I doing wrong? Everything else works in the ahs_dev site.
 
Thanks,
 
Mark

Go to the error_log of ahs_dev, remove or #comment out the line with
NotFound.  Then try adding that external method again and see if that
now gives you a proper traceback; hopefully that contains more hints.
When you get a 404 on a page it is not always that page itself that
cannot be found.

Having said that, I *can* imagine that the separate Data.fs files are
the cause for the problem here; if that is the case then I would call
this a bug.

Maurits,
 
Thanks for the pointer...I forgot about how the error log filters out certain errors.
 
The error said that it could not find the method in my python file. Well, it is there. Then I realized I was cutting and pasting the ID, method name, etc. from the ahs site to the ahs_dev site. I inadvertently added a trailing space, so the method could not be found. I would call this a bug, since I believe a method name in python cannot have a trailing (or leading) spaces. In the traceback below, and you can see the trailing space in the method name that was picked up by the add external method form:
Traceback (innermost last):
  Module ZPublisher.Publish, line 115, in publish
  Module ZPublisher.mapply, line 88, in mapply
  Module ZPublisher.Publish, line 41, in call_object
  Module Products.ExternalMethod.ExternalMethod, line 59, in manage_addExternalMethod

  Module Products.ExternalMethod.ExternalMethod, line 111, in __init__
  Module Products.ExternalMethod.ExternalMethod, line 134, in manage_edit
  Module Products.ExternalMethod.ExternalMethod, line 141, in getFunction

  Module App.Extensions, line 158, in getObject
   - __traceback_info__: ('/opt/Plone-2.5.5/zeocluster/client1/Extensions/WorkflowEmailScripts.py', 'WorkflowEmailScripts')
NotFound: The specified object, <em>edit_new_content </em>, was not found in module, <em>WorkflowEmailScripts</em>.
If my understanding of python is correct, shouldn't manage_addExternalMethod stip off leading and trailing white space from the id, title, module, and function names passed into the method? In ExternalMethod, manage_addExternalMethod does this:
    id=str(id)
    title=str(title)
    module=str(module)
    function=str(function)

should it be?
    id=str(id).strip()
    title=str(title).strip()
    module=str(module).strip()
    function=str(function).strip()
 
Thanks again for shining a light on an otherwise murky road to understanding! How would I submit a bug report, if you think there is a bug here. Just a newbie trying to give back.
 
Mark

Go to the error_log of ahs_dev, remove or #comment out the line with

Such a change would make sense for me.
