    text
    <p>Under Akka 2.10 my logging configuration is being reset during shutdown... resulting in potentially-important messages being written to standard output rather than the logging mechanism. </p> <p>For example, this code:</p> <pre><code>String settings = "akka.event-handlers = [\"akka.event.slf4j.Slf4jEventHandler\"]\n" + "akka.actor.provider = \"akka.cluster.ClusterActorRefProvider\""; Config config = ConfigFactory.parseString(settings); ActorSystem system = ActorSystem.create("testing", config); LoggingAdapter log = Logging.getLogger(system, new Object()); log.info("Via SlF4J"); system.shutdown(); Thread.sleep(1000); log.info("After shutdown"); </code></pre> <p>Produces this output:</p> <pre><code>17:24:11.999 [testing-akka.actor.default-dispatcher-4] INFO akka.event.slf4j.Slf4jEventHandler - Slf4jEventHandler started 17:24:12.151 [testing-akka.actor.default-dispatcher-4] INFO N.168.1.106:2552) - RemoteServerStarted@akka://testing@192.168.1.106:2552 17:24:12.155 [testing-akka.actor.default-dispatcher-4] INFO java.lang.Object - Via SlF4J [INFO] [04/12/2013 17:24:12.218] [testing-akka.actor.default-dispatcher-4] [NettyRemoteTransport(akka://testing@192.168.1.106:2552)] RemoteServerShutdown@akka://testing@192.168.1.106:2552 [INFO] [04/12/2013 17:24:13.156] [main] [Object(akka://testing)] After shutdown </code></pre> <p>The first three lines of output are via SLF4J (my configured logger), whereas the final two are via <code>akka.event.Logging$StandardOutLogger</code> -- which means that exceptions being logged during shutdown (and I am seeing a few, in some circumstances) are being lost to the logger.</p> <p>(It would also be nice to see the RemoteServerShutdown message logged correctly, of course.)</p> <p>Anybody have any insight into this behavior?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
