[seam-dev] First cab off the rank!

[Shane Bryzak]

Remoting now has full support for looking up qualified beans, so you can 
now do cool stuff like this:

<script type="text/javascript">
     function sayHello() {
       var name = prompt("What is your name?");
       if (name == null) return;
       var callback = function(result) { alert(result); };
       
Seam.Component.create("org.jboss.seam.remoting.examples.helloworld.HelloAction", 

          "@HelloQualifier(foo = 123, bar = 
String.class)").sayHello(name, callback);
     }
</script>


@Retention(RUNTIME)
@Target(TYPE)
@Qualifier
public @interface HelloQualifier {
    int foo();
    Class bar();
}

@HelloQualifier(foo = 123, bar = String.class)
public class HelloAction {
   @WebRemote
   public String sayHello(String name) {
     return "Hello, " + name;
   }
}

If the bean is @Named then you can simply pass in the name to 
Seam.Component.create() in JavaScript, otherwise you can use a 
combination of bean type and qualifiers.  I need to still do some work 
on the API, instead of Seam.Component.create() I'm thinking 
Seam.Bean.instance() instead.
