Perhaps more constructively, I think you can solve this by either
adding a dummy element to the tuple:
return dd[4:] + (None,)
or making it a list instead of a tuple:
return list(dd[4:])

I tried 2.6 as well. Check the source of the returned page.
I think you will find this:
Workspace.2003-12-17.8140751750
gerry.2003-12-17.8140751750
It seems to happen with any tuple... I tried this script:
return ('foo', 'bar')
... and got this:
foo
bar
Returning a list instead of a tuple is OK - it shows a string
representation of the list.
I would guess that you are right, this is odd publisher behavior.
File a collector issue.

Look at the title of the browser window to see the other item of the tuple.

[Zope-dev] bizarre slicing behaviour in Zope
try this in a script in zope 2.7b3 (maybe others, too) if you want to go
crazy:
dd = ('dd', 'diocese', 'Parish.2003-12-16.8636751973', 'bob',
'Workspace.2003-12-17.8140751750','gerry.2003-12-17.8140751750')
return dd[4:]
you should get the last two items from the tuple, but I get the last
item returned as a string
if i loop through the slice, it's ok. it seems to be a publishing problem.

It's fixed, though I would like to discuss it a bit more. It *seems* to me that the Zope HEAD is being more picky about storing acquisition wrappers, which on one side is a good thing. OTOH, it was relatively hard to track it down, meaning several visits to gdb. The fact that the parameter is called 'Wrapper' at 'Wrappers_are_not_picklable' makes it even harder, because is practically impossible to cast the object to a Wrapper. So, I would like to propose two changes: 1. Rename the 'Wrapper' parameter to 'wrapper' in that function 2. Include 'Wrapper->container' and 'Wrapper->obj' in the traceback, in order to make it easier for people to find out where is the problem when it happens. (note that the 'Wrapper' parameter is not even being used currently) Thoughts? -- Sidnei da Silva <[EMAIL PROTECTED]> http://awkly.org - dreamcatching :: making your dreams come true http://plone.org/about/team#dreamcatcher "Don't fear the pen.
