Body
I'm new to scala. When learning Actor, I tried to extend it to save one line of def: <pre><code>import scala.actors.Actor import Actor._ class Actoo(actoo: =>Unit) extends Actor { def act() {actoo} } object run extends Application { /* // this one runs well val a = new Actor { def act() { receive { case 1 => println("1") } } } */ val a = new Actoo { receive { case 1 => println("1") } } a.start a ! 1 } </code></pre> Then the exception trace looks like this: <pre><code>java.lang.AssertionError: assertion failed: receive from channel belonging to other actor at scala.Predef$.assert(Predef.scala:92) at scala.actors.Actor$class.receive(Actor.scala:424) at Actoo.receive(actoo.scala:3) at run$$anon$1.<init>(actoo.scala:16) at run$.<init>(actoo.scala:15) at run$.<clinit>(actoo.scala) at run.main(actoo.scala) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at scala.tools.nsc.ObjectRunner$$anonfun$run$1.apply(ObjectRunner.scala:75) at scala.tools.nsc.ObjectRunner$.withContextClassLoader(ObjectRunner.scala:49) at scala.tools.nsc.ObjectRunner$.run(ObjectRunner.scala:74) at scala.tools.nsc.MainGenericRunner$.main(MainGenericRunner.scala:154) at scala.tools.nsc.MainGenericRunner.main(MainGenericRunner.scala) </code></pre> There may be many alternatives which can do the same thing, but it's better for me to know the reason why the code above doesn't work.

Guidance

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.
