possible logical bug during key creation

[GoogleCodeExporter]

I discovered a sneaky bug, which can happen due to a developer's mistake.

class Party {
@Id Long id
....
}

In one of my UI screens, I do a post of id (from the above Party), and on the 
server, that
'id' is received as a String.  Hence, the Party key can be created using String 
id.
Key<party> key = new Key(Party.class, id)
ofy.get(key)
I will never get the Party entity back, because the Party was creating using 
the long id.

The Keys constructed with 'String id' and 'long id' are different.

Can any error checking be done while creating the Objectify Key.

Adding to the issue...
What, if the key is created using string id instead of long id, and then the 
key is stored in other entities.

So, it is better to do proper checking during Key creation.

As someone was pointing in the group, on how to introduce more logic in 
GWT-Safe objects.  An interface can be introduced that validates the key 
creation logic.  The interface then could be safely sent in GWT safe class.
