[web2py] accepts > KeyError: '_id', latest trunk with postgresql

[Carlos]

Hi,

I'm getting the following error with latest trunk and postgresql, 
especially after changeset # fab104bec898 (web2py-py3k: proof of concept).

  File "C:\web2py\gluon\sqlhtml.py", line 1082, in accepts
    hideerror=hideerror,
  File "C:\web2py\gluon\html.py", line 1807, in accepts
    status = self._traverse(status,hideerror)
  File "C:\web2py\gluon\html.py", line 749, in _traverse
    newstatus = c._traverse(status,hideerror) and newstatus
  File "C:\web2py\gluon\html.py", line 749, in _traverse
    newstatus = c._traverse(status,hideerror) and newstatus
  File "C:\web2py\gluon\html.py", line 749, in _traverse
    newstatus = c._traverse(status,hideerror) and newstatus
  File "C:\web2py\gluon\html.py", line 749, in _traverse
    newstatus = c._traverse(status,hideerror) and newstatus
  File "C:\web2py\gluon\html.py", line 756, in _traverse
    newstatus = self._validate()
  File "C:\web2py\gluon\html.py", line 1572, in _validate
    (value, errors) = validator(value)
  File "C:\web2py\gluon\validators.py", line 549, in __call__
    elif str(rows[0]._id) != str(self.record_id):
  File "C:\web2py\gluon\dal.py", line 5003, in __getattr__
    return self[key]
  File "C:\web2py\gluon\dal.py", line 4994, in __getitem__
    return dict.__getitem__(self, key)
KeyError: '_id'

This error does not occur when reverting to changeset # dafe70b55ae5 (oops, 
some tests were not committed, now they are).

Is this a bug?.

Thanks.
