Re: [appengine-java] Re: Local datastore is empty after migrating to 1.3.1
I'm pretty sure the your datastore is empty message on the admin data viewer pages doesn't mean that his query, in his application code, returned no results. While I don't disagree with you that the data is still in there I'm pretty what you just described is documented in the behavior of indexes in the data-store pretty thoroughly. If you don't index a property (or don't store it) you can not sort or search for it. As an example of your data is there, but completely invisible, try changing your app-id in your appengine-web.xml and looking at the admin page data viewer after a restart.

For example, following happened in my case: I had a query that retrieves my (root) entities, but they are ordered by sequence_id . In 1.3.0., this query worked fine even if sequence_id is un-initialized (is null). With 1.3.1., somehow entities with null sequence_id do not show up in query results - and in development I had neglected to set this field at all. So, getting empty results back: and this may lead you to think that data has been lost. Though I found out that if I remove order by from the query, all results show up - the data is still there. Now, from correctness standpoint, excluding null entities from order by query is ok - as you can't compare against null (per SQL rules) - so such rows may be dropped. Anyway, what I did, I wrote a small migration script to load all my entities, initialize sequence_id = 0 and save them. And it's now working fine with 1.3.1.
