FWIW You don't need Keys ***in JDO*** at all either ... when the JDO

I think you already arrived the recommended solution to the issue of
counting entities. For reference, the reason that the production environment
only returned at most 1,000 is an artifact of the query mechanism that App
Engine uses which can only return up to 1,000 results per query.

Beats me. It seems to be some sort of pixie dust you'll often need to apply.
You don't need it for String, Long, Date, and a variety of other jdk classes,

used in the GAE web site's documentation.

Andy has pinpointed the issue. You most likely don't have a field on your

query because your second call to setFilter() is overwriting the reference

Hi Sanjith. All App Engine requests must return within 30 seconds or this

sorry for the delay,
