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

Created an editable flex grid which exposes a method called getGridData() to javascript. I am using the JSON.encode() method of the [url]....library to convert the grid object's dataProvider into JSON before returning it.
ExternalInterface.addCallback("getGridData", getGridData);
public function getGridData():String

However, when I sort a column in the user interface, the encode method is failing throwing the following error
Property usingCustomCompareFunction not found on mx.collections.SortField and there is no default value.
what the differences or similarities are between these and if there is some actionscript tool to convert back and forth between these types.
the data i'm getting is coming in from mysql in the form of name,job
joe, doctor
moe, lawyer
etc...
I need to convert this to dataProvider and then also to Json for some graphing program that can read json or xml.

View 3 RepliesI'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:

I have to work with webservices in Actionscript. I found the following code that allows me to use JSON URLs that implement only the GET method. However, it doesn't work for POST methods (doesn't even enter the "onComplete" method). How can i "POST" JSON data using Actionscript 3.0?

I was wondering if someone could explain or point me in the direction of how to implement an API that uses JSON in ActionScript 3.0. What I specifically want to know is how would I grab specific information. The following is how I do it in XML but I don't know how I would do something similar in JSON as in getting the equivalent of an XML tag.

I'm using Flex 4 for building the communication to Arduino. There are three (3) main values coming from it (X,Y,Z). Here the Flex's code

d = JSON.decode(newText.text);
MNx = d["x"];

I'm using Flex 4. Have PHP backend and mysql database with one table consisting of multiple rows. I take the raw data from the result event and decode it using JSON. I then dump the data into an ArrayCollection that I use as my datagrid's data provider.
My question is how can I tell when someone inserts a new row into the mysql table so that I can automatically refresh my ArrayCollection, thus seamlessly updating my datagrid one element at a time? Right now, it's just a one time call and the connection is closed. If someone inserts a new row into the database my program doesn't recognize, unless I restart it. I'd like to auto-update the AC whenever a single new row is inserted into the mysql database. Is there a way I can "listen" for this change?

I need to parse a large trace file (up to 200-300 MB) in a Flex application. I started using JSON instead of XML hoping to avoid these problems, but it did not help much. When the file is bigger than 50MB, JSON decoder can't handle it (I am using the as3corelib).
Try to split the file: I would really like to avoid this; I don't want to change the current format of the trace files and, in addition, it would be very uncomfortable to handle.Use a database: I was thinking of writing the trace into a SQLite database and then reading from there, but that would force me to modify the program that creates the trace file.
I am trying to set the json content type on httpservice to make REST service return the json data. When I add the content type in fiddler all works fine so the problem lays in flex application, not in the web-service. But the code below does not work and I get the xml data instead of json.
mxml:
<s:HTTPService id="service" method="POST" url="server.com" result="loaded(event)" fault="fault(event)" useProxy="false" resultFormat="text">
Actionscript:
public function loadAllSamples():void {
service.contentType = "application/json";
service.send('something');
}
I have done some searching around, and from what it looks like so far, there is no native way to parse JSON in Actionscript/Flex. XML is automagiaclly parsed and life is good. Why isn't JSON parsed this same way?
View 1 RepliesIn a very simple first AIR application (I'm using Flash Builder 4.5), I am trying to accomplish the following on my MacBook:
Read a local file (JSON format) into the AIR app. Parse through the file. Display some selected contents in a grid.
That's it.
I've found an example that does some simple JSON parsing in Flex, but the problem is that it loads the JSON source from a remote web site.
So do I need to load any file-specific libraries to make this work in AIR? Or can I simply refer to the file by using the Mac file-path? I just want the local file to be the JSON source. The parsing is already taken care of.
