key error

Platform:
      instantpress_beta6.zip
      web2py Current Version 1.91.6 (2011-01-03 17:55:14)
      GAE sdk 1.4 (appspot.com)

I have deployed a instant press on GAE with the latest web2py 1.91.6 .
I can use site admin panel to add a new article, but can not change its title. 
The error logs from GAE as below:
--------------------------------------

BadFilterError: BadFilterError: invalid filter: __key__ filter value must be a 
Key; received 108002 (a long).
----------------------

I says we can not use id filter like 'db.posts.id != id', because id is not key 
property but long type.
where does this bug come from? instantpress, web2py or GAE?

I think is web2py issue, was fixed 2 days ago. 

http://code.google.com/p/web2py/issues/detail?id=154&can=1&start=100

Can you test with web2py trunk?

Thank you,I tested it successful after it fixed. 

In addition, we have to uncomment line 2447 of dal.py like below:
    from google.appengine.api.datastore_types import Key  ### why was this needed????

Otherwise, we will meet NameError as:
  File "gluon/dal.py", line 2577, in NE
    second = Key.from_path(first._tablename, long(second))
NameError: global name 'Key' is not defined

Thank you very much!
