Errors after migration

[András Belicza]

Hi,

Since the M/S database is now deprecated, I decided go along with the migration. My app id is sciigears. The migration process went ok, but after that I experience errors.

First of all, the Datastore viewer of the Admin console does not show all entities of a kind. What? How can this be? If my application performs a query, it lists entities that do not appear on the datastore viewer page (I order the entities by the same property, same direction...). The missing entities were present in the old app, they should be present in the new. I guess they are since the query run by the app code returns them...

Second, I'm not able to read the migrated blobstore files. I get the following error:

java.io.IOException
	at com.google.appengine.api.files.FileServiceImpl.translateException(FileServiceImpl.java:601)

Please look into it. Thanks.
