    <p>You could use <a href="http://doc.akka.io/docs/akka/snapshot/scala/futures.html" rel="nofollow"><code>after</code></a> from <code>akka</code> instead of blocking <code>Await.result</code>:</p> <pre><code>val timeout = akka.pattern.after(FiniteDuration(60000, MILLISECONDS), using = system.scheduler){ Future.successful(None) } val resFuture = for { result1 &lt;- Future firstCompletedOf Seq(future1.map{Some(_)}, timeout) result2 &lt;- Future firstCompletedOf Seq(future2.map{Some(_)}, timeout) } yield (result1, result2) val result = resFuture map { case (Some(r1), Some(r2)) =&gt; Merge(r1, r2) case (Some(r1), None) =&gt; PartialResult1(r1) case (None, Some(r2)) =&gt; PartialResult2(r2) case _ =&gt; EmptyResult } </code></pre> <p>In this case <code>resFuture</code> will be completed in 60 seconds and you can process partial result. Also you don't need <code>Await</code> in <code>Play</code> - you could use <a href="http://www.playframework.com/documentation/2.3-SNAPSHOT/ScalaAsync" rel="nofollow"><code>Async</code></a>.</p> <p>In case you have many equivalent futures of the same type you could use it like this:</p> <pre><code>val futures: Seq[Future[Int]] = ??? val futureWithTimeout = futures.map{ f =&gt; Future firstCompletedOf Seq(f.map{Some(_)}, timeout) } val result: Future[Seq[Option[Int]]] = Future.sequence(futureWithTimeout) // In case you need to know index of completed or not completed future val indexedResults = result.zipWithIndex // In case you just need only completed results val completedResults: Future[Seq[Option[Int]]] = result.map{_.flatten} </code></pre> <p>Types here are only for illustration.</p>

    1. COGiven the use of Play you have Akka on the classpath so the above example is great. Where there is no Akka you need an alternate scheduler. This resource is helpful there: http://stackoverflow.com/questions/16304471/scala-futures-built-in-timeout

    2. COYeah, that helps. I am trying to try it out. I am having trouble to use it. The compiler tells me Not Found System for using = system.scheduler. I should import what? I cannot find a centralized doc which can tell me which package to import when using it's function.

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.
