Re: Mapping objects

I think the important change here was in your constructor. 
The following code will _not_ do what you want, I should have 
caught it earlier. 

>> ActionScript Code for SmackletType:
>>
>> class SmackletType {
>>
>>  // class properties
>>  private var _smackletName:String;
>>  private var _smackletTeaseLink:String;
>>  private var _smackletLink:String;

>>
>>  // constructor
>>
>>  public function SmackletType(smackletName:String,
>> smackletLink:String, smackletTeaseLink:String, smackletThumb:String) {
>>
>>   _smackletThumbnail = smackletThumb; // Bad for remoting. Will null out smackletThumbnail 
>>   _smackletTeaseLink = smackletTeaseLink;
>>   _smackletLink = smackletLink;
>>   _smackletName = smackletName;
>>
>> } // SmackletType constructor


Remoting will create a SmackletType object, populate the
instance variables, and finally call the constructor. 
But it won't pass any _arguments_ to the constructor. 
So, the constructor above will actually reset 
your instance variables like _smackletThumbnail 
back to null, because the smackletThumb argument is null.

If I am making an ActionScript class which is sometimes
instantiated via Remoting, and sometimes instantiated from
ActionScript code, I do something like this:

 public function SmackletType(smackletName:String,
	 smackletLink:String, smackletTeaseLink:String, smackletThumb:String) {

	if (arguments.length == 4) {
		// Class was instantiated from ActionScript w/ all arguments
 		   _smackletThumbnail = smackletThumb;  
		   _smackletTeaseLink = smackletTeaseLink;
		   _smackletLink = smackletLink;
		   _smackletName = smackletName;
	} else if (arguments.length == 0) {
		// Class was probably instantiated via Remoting.
		// You might test to ensure that smackletThumbnail 
		// or other instance variables are defined as expected.
	} else {
		// Class was called from ActionScript with wrong number of arguments. 
		// --> programmer error.
	}
}
