Re: instanceof validation error on checking value obects from server

Troy,

You are the man! I updated all our value objects in our value object 
register class and instanceof is returning true for us now. We have a 
ValueObject.as class we use to do this; I am posting the code below as a 
convenience to others. Our slip up is/was that we were using the same 
args that we used in our openamf-config.xml for our 
Object.registerClass(). Lesson learned (the hard way).

Thanks,
Jonathan

class ValueObjects
{
    // Properties
    static private var inst = null;

    function ValueObjects()
    {   
    }
   
    static public function getInstance()
    {
        // Singleton access
        if(inst == null)
        {
            inst = new ValueObjects();
        }
        return inst;
    }
   
    public function registerValueObjects()
    {
        //
        // Add all value objects used in this application here. Each needs
        // to be registered as a class for Flash Remoting to successfully
        // map incoming objects to AS classes. The same is true for outgoing
        // value objects.
        //
        // registerValueObject("com.flash.classpath.to.ValueObject",
        //                                 
com.flash.classpath.to.ValueObject);
        //
        // In OpenAMF, using the Advanced Gateway, you also have to update
        // the openamf-config.xml file and add a custom class mapping 
for each
        // value object, in the following form:
        //
        //    <custom-class-mapping>
        //        
<java-class>com.java.classpath.to.ValueObjects</java-class>
        //        
<custom-class>com.flash.classpath.to.ValueObjects</custom-class>
        //    </custom-class-mapping>        
        //
        TRACE(Flashout.INFO + "ValueObjects: Registering value objects");
                        
        registerValueObject("com.flash.classpath.to.ValueObject",
                                        com.flash.classpath.to.ValueObject);

    }
   
    private function registerValueObject(remoteObject, localObject):Void
    {
        var result:Boolean = Object.registerClass(remoteObject, 
localObject);
        if(result == false)
        {
            TRACE(Flashout.ERROR + "ValueObjects::registerValueObject, 
Could not register " + remoteObject + " to local object.");
            throw new Error("ERROR: ValueObjects::registerValueObject, 
Could not register " + remoteObject + " to local object.");   
        }
        else
        {
            TRACE(Flashout.INFO + "ValueObjects::registerValueObject, 
successfully registered " + remoteObject + " to localObject.");
        }
    }
}
