Is there a way or a library made to deserialize a JSON string into a typed object in ActionScript and Python?
For eg.
class Person
{
String name;
[code]....
So, the last statement basically casts the object we get after deserializing the jsonString into the Person object.
note: using django/python/javascript/flash So its been two days since I'm stuck at the error. I did the things you told me to and found a couple of ways around it but nothing worked. These are the results.Javascript does not receive the normal string it has to be a json object so. in views.py
somestring = json.dumps("HELLO WORLD")
which renders this in HTML
"HELLO WORLD"
and in javascript it is rendered like this
a240527176321_quote_hello
Now, since it is a json object I need to convert it back in flash. But when it gets in flash where I receive it like this
function something(hellovar){
.....
......
}
it does not even come inside the function.
I have a pure ActionScript 3 problem, but the simplified test case I've prepared is in Flex 4 for better visibility (the source code is below): Since Flash Player 11 / AIR 3 support JSON natively, I've decided to move a multiplayer game, which used XML for communicating with server, to JSON. But I have a frustrating problem, that given two Objects like
[Code]...
The jist of what I'd like to know and focus on understanding, is details on how binary deserialization occurs in Flex 3. When is the constructor called, when are properties set, are private members serialized or does all deserialization occur on and through setters, etc? I'm having a hard time finding information on this.In a Flex 3 AIR application, I have a pretty complex object graph(just a bunch of objects referencing one another, kinda like a big data model except a bit more complex) that I serialize to a file using a single call on the FileStream.writeObject and readObject on a root object, which serializes and deserializes the entire object graph.I found that I needed to always have a default constructor, else I would get exceptions on the objects when deserializing if they were part of an ArrayCollection. So I had to eleminate the constructor parameters or set default values. I now have many setters like this in my classes, such as the below where mConnection accumulates some information it needs through different setters, where as before I had this all packed into the constructor since all of the information is really necesary for the Connection to function:[code]So the connection's serverIP is still an empty string because the server was assigned to the client's property before the server was completely initialized.
I could probably resolve this by using binding so that updates to the serverip in the server are bound to the connection, but I find binding properties to be fairly complicated (it's really simple on UI in mxml cause you just use the curly bracket syntax but doing it by code is what I found complicated). I have also resolved some cases by removing the constructor parameters entirely, so that there is no default values. All that aside, I still really need a deeper understanding of the details of binary serialization as far as how it rebuilds the object graph. I even have circular references, and it seems to handle those fine and maintain multiple references without duplicating objects. It's just when my constructors/setters are more complex that I'm running into these problems because of the order of what occurs during deserialization. It is really inconsistent though, as adding breakpoints in various places seems to influence the order that things occur, making it more difficult to debug.On a side note for anyone that might sidetrack the topic because I am serializing a class called Connection. I added some code to address some things, like in the Connection class there is an instance of a Socket. Of course my socket would not be connected after I close and reopen the application and deserialize it, so before I serialize my object graph, I go through and close the socket and set the reference in the Connection class to null, so that there is no longer a reference to the socket and thus it will not get serialized. After deserialization on the next application run I create a new socket.
We have an Adobe Flex client talking to a .NET server using WebORB. Simplifying things, on the .NET side of things we have a struct that wraps a ulong like this:
public struct MyStruct
{
private ulong _val;
[Code]....
I've tried playing with custom WebORB serializers, but the documentation is a bit scarce. Is this possible? If so how?
I think I can work out how to serialize it, but not the other way. Do I need to write a Custom Serializer on the the Flex end as well?
I experience strange behavior of sockets in Python (3.2). Client connects to my application using Flash. Most of the time there is nothing unusual but sometimes python crashes in a way that should not have taken place - enter into infinite loops.

I'm working on a Flash AS2 application that needs to post JSON data to a web service.In previous projects, I've used LoadVars.send() or LoadVars.sendAndLoad() successfully to manage this:
var send_lv:LoadVars = new LoadVars();
send_lv.data = JSON.stringify({some json object});
var response_lv:LoadVars = new LoadVars();
response_lv.onData = function(rawdata) {
[code]....
In somepage.php, I can grab that JSON data using $_POST['data'].However, on this project, the developer of the web service requires the JSON content to be the BODY of the request (i.e., not a name/value pair). Is this possible with LoadVars?

I have a json object where I don't know some of the values at compile time, but I do know that all objects will be valid at runtime. So in the example below, the first trace will output "50" and I want the second trace to output "100", the value of someObject.someparam, which gets defined at runtime.
var plan:Object = { "testParam": 50, "testParam2": "someObject.someParam" }
var someObject:Object = {"someParam": 100}// this actually doesn't get defined until runtime
trace ("testParam " + plan.testParam);
trace ("testParam2 " + someSortOfInterpreter(plan.testParam2);

So I just started using JASON to make my application data driven. I'm not doing any encoding, only decoding (I encoded once to create an example data layout).

I'm writing a mock backend service for my flex application. Because I will likely need to add/edit/modify the mock data over time, I'd prefer not to generate the data in code like this:
var mockData = new Array();
mockData.push(new Foo(1, "abc", "xyz"));
mockData.push(new Foo(2, "def", "xyz"));
...
Rather I'd like to store the data in a file in some format that it can be easily serialized into my strongly-typed value objects (i.e. Foo above). Ideally I'd like to create the data in a self-describing format(i.e. what data type each field is, what class it represents, etc)
