Hi,
yesterday my application worked just fine. Today data isn't reachable
with a simple query anymore (data is here, I can find it through the
Data Viewer).
Here is the exception thrown:
----------------
Uncaught exception from servlet
The primary key for mymodel.JarData is an unencoded string but the key
of the corresponding entity in the datastore does not have a name. You
may want to either change the primary key to be an encoded string (add
the "gae.encoded-pk" extension), change the primary key to be of type
com.google.appengine.api.datastore.Key, or, if you're certain that this
class will never have a parent, change the primary key to be of type Long.
org.datanucleus.store.appengine.FatalNucleusUserException: The primary
key for mymodel.JarData is an unencoded string but the key of the
corresponding entity in the datastore does not have a name. You may
want to either change the primary key to be an encoded string (add the
"gae.encoded-pk" extension), change the primary key to be of type
com.google.appengine.api.datastore.Key, or, if you're certain that this
class will never have a parent, change the primary key to be of type Long.

My question: how can it happen, that changes in DataStore have such
breaking consequences? And how often will it happen?
Cheers,
Marc.
