Hi Davy, What you are experiencing is an expected behavior, this are some of the changes we made to the SDK in order to simulate High Replication Datastore behavior on the local development server.
Since SDK 1.5.1: http://code.google.com/p/googleappengine/wiki/SdkForJavaReleaseNotes#Version_1.5.1_-_June_20,_2011 The development server's datastore and testing service implementations now contains logic that closely replicates the consistency guarantees of the High Replication datastore This will let you test how your application will feel when running on production, get a good understanding of Eventual Consistency and use Datastore characteristics to make Strongly consistent queries (using entity groups, ancestor queries and key queries), A good article to read along would be: http://code.google.com/appengine/docs/java/datastore/hr/overview.html Development server documentation: http://code.google.com/appengine/docs/java/tools/devserver.html#Using_the_Datastore Any question, don't hesitate to ask! Hope this helps! Happy coding on App Engine!
