Getting ArrayList from Custom Code

Question

Hi,

I have created a custom coded jar. It has an array which contains some of messages from buddies of a user. I deployed it, on tests everyting went fine.

I got response and traced well. But when I want to get response as array, there is a problem.

On server side; 

ArrayList<Buddy> buddies = getMessagesOfUser(messageIds);

JSONObject jsonResponse = new JSONObject();

jsonResponse.put("buddies",buddies.toString());

On client side; ( I am using AS3 API)

var array:Array = new BuddyResponseBuilder().buildArrayResponse(response.buddies);

I got error :

 

TypeError: Error #1009: Cannot access a property or method of a null object reference.

How can I solve that?

 

Thanks,

Can you just parse only for first element and check if it works? Something like this.

var array:Array = new BuddyResponseBuilder().buildArrayResponse(response.buddies[0]);

nope. I received  property 0 not found on String error.

Hello,

 

On the server side, when you are putting the value in json object update the code snippet with below code: 

 

ArrayList<Buddy> buddies = getMessagesOfUser(messageIds);

JSONObject jsonResponse = new JSONObject();

jsonResponse.put("buddies",buddies.get(0).toString());

 

And fetch it back in your app using the below code snippet:

 

var buddyMessageArray:Array = new BuddyResponseBuilder().buildArrayResponse(jsonResponse["buddies"]);

 

let us know if it helps.
