Re: RequestFactory remove() not working

Hello,

the RF Servlet (check JsonRequestProcessor#getSideEffects() method)
try to get your entity (using your find static method) to determine
the type of WriteOperation to return to the client. It return a DELETE
operation only if it get a null return value.
To have this behavior, you've to handle the Exception thrown by your
data backend when it doesn't find an entity. For example, in my
Message JDO entity, i'm doing this :

public static Message findMessage(Long id) {
PersistenceManager pm = PMF.get().getPersistenceManager();

try {
return pm.getObjectById(Message.class, id);
} catch(RuntimeException e) {
return null;
} finally {
pm.close();
}
}

If you don't catch the exception, a ServerError is returned back to
the client.

Anthony.
