I usually make a another class, e.g. K12Thread and then add static methods on that do my casting etc. e.g.
public static User user(EOEditingContext ec)
{
return isAttached() ? ((User)ERXThreadStorage.valueForKey(USER_KEY)).localInstance(ec) : null;
}
Which results in:

You could also add this in K12GenericRecord or a suitable superclass:
public User activeUser()
{
return K2Thread.user(editingContext();
}
And then in your code:
