--------------------------------
Resolution: Cannot Reproduce Bug
I cannot reproduce this issue. Here's the test case I tried:
Server-side Seam component:
@Name("test")
public class Test
{
@WebRemote
public List getTestItems() {
List values = new ArrayList();
values.add("Foo");
values.add(123);
values.add(new Date());
Foo foo = new Foo();
foo.setValue("Bar");
values.add(foo);
return values;
}
}
Server-side POJO bean:
package org.jboss.seam.example.remoting;
public class Foo {
private String value;
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
}
Client-side include:
<s:remote include="test,org.jboss.seam.example.remoting.Foo"/>
Client-side code:
function test() {
var test = Seam.Component.getInstance("test");
test.getTestItems(testCallback);
}
function testCallback(result) {
for (var i = 0; i < result.length; i++)
{
alert(result[i]);
if (Seam.Remoting.getTypeName(result[i]) == "org.jboss.seam.example.remoting.Foo")
alert(result[i].getValue());
}
}
With this test case everything works as expected. If you can still reproduce the issue then I'm going to need a more detailed test case.

> Key: JBSEAM-2547
> URL: http://jira.jboss.com/jira/browse/JBSEAM-2547
> Project: JBoss Seam
> Issue Type: Bug
> Components: Remoting
> Affects Versions: 2.0.0.GA
> Environment: JBoss 4.x AS, Javascript and Seam Integration
> Reporter: P C
> Assigned To: Shane Bryzak
>
> Through the use of Seam Remoting, I find that there is a "bug" in how seam decodes Collection objects on the client side (javascript). For example, on the server side, I am doing the following in a stateless seam bean:
> @Stateless at Name ("test")
> class TestAction implements Test {
> List getTestItems() {...}
> }
> On the Client Side (Javascript):
> var test = Seam.Component.getInstance("test");
> test.getTestItems(callBack);
> var callBack(result) {
> }
> When the seam proxy decodes the message it cannot determine the object types inside the returned collection so it returns someting undefined. But if I define Generics then it works:
> List<ConcreteClass> getTestItems() {...}
> It seams to me that the Seam Proxy has trouble parsing objects in an abstract collection.
