You're 100% correct. If the same index entry is in
*datastore-indexes-auto.xml* GAE should be automatically building the index
for you, there's no need to add it to *datastore-indexes.xml* as well.

Can you try changing the version setting of the application, then
reuploading it to the same application ID on App Engine? Sometimes App
Engine gets "stuck" on a certain configuration; it may recognize the new
index in a new version. If you're using Eclipse, you can change your
application's version by going into the *App Engine Project Settings* pane.

You can do an index from any Java numeric type: int, float, double, and so
forth (including their object wrappers such as java.lang.Integer, Float,
Double, etc).
