datastore and updating values

[Quiark]

Hi, I was playing a little with GAE and this code and it seems that in order to be able to change an entity in the datastore, you must use the same Entity object that you get from the datastore. Using the same Key apparently is not sufficient. Therefore the design of your datastore functions is insufficient, because the Entity object is discarded.

I will probably fix it for myself by adding the object to the map, so it's possible to update the data using it.
