Hello,

I have a very weird problem. I am appending to a list a piece of data 
that I have retrieved from a ZSQLMethod within an external method. That 
piece of data happens to be type date. This is with Zope 2.4.

Error Type: TypeError
Error Value: __init__() takes at least 3 arguments (2 given)

Traceback (innermost last):
  File C:\Zope\BELENS~1\lib\python\ZPublisher\Publish.py, line 223, in

  File C:\Zope\BelenSite\Extensions\getDataForWeeklyReport.py, line 68, 
in getDataForWeeklyReport
    (Object: LockableItem)
TypeError: (see above)

When I test it on 2.3 the last line of the traceback says 
(Object:Traversable)

I have no clue what the problem might be. :-(
Any help will be really appreciated.

Thanks in advance

Belen
