Actionscript 3 :: Unable To Assign JSON Decoded Object As DataProvider
Oct 14, 2010
I am trying to use JSON decoded as a dataProvider, but no matter what I try I get errors such as the following: Error #1034: Type Coercion failed: cannot convert mx.collections::ArrayCollection@2a88ae01 to fl.data.DataProvider.
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). My question is, how come I can't cast the data that I read in into the object that it is? I know that question is useless without an example so here goes:This is my data class that I encoded once to create an example JSON file.
I am loading a php file and calling this function decodeJSON want to parse the data and dispaly it into a combo box but when i do a trace all i get is [object Object],[object Object],[object Object]Here is the code
function decodeJSON(event:Event):void{ var loader2:URLLoader = URLLoader(event.target); var jsonArray:Array = JSON.decode(loader2.data) as Array;
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 {[code].....
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.
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
I'm trying to serialize and deserialize a byte array to a string using Base64 for as3.
Here is my code
public function Serialize(vector:Vector.<Action>):String { var bytes:ByteArray = new ByteArray(); var serialized:String = "";
[Code].....
is the error I get after calling deserializedObj = deserialized.readObject(); Should I be get that error if I'm just trying to put this into an object? I'm not trying to put it into an action class object yet, but if it is then the action it's getting doesn't have parameters that were originally inside.
i have a method with brings data of particular table, as given my parameter to that method,
now i want to fetch data from corresponding table and it too list, and send back flex and form dynamically Grid & add dataprovider dynamically as for its corresponded table colomns in flex side ?
Now i want this create a Datagrid in flex dynamically by using its design & master data table in action script i done everyting , my dataGrid had formed as for his master design,but data is not showing ?
If I open a new Flash (AS3) file in Flash CS3 Professional and try to import DataProvider (import fl.data.DataProvider;), I consistantly receive a compiler error (1172: Definition fl.data:DataProvider could not be found).
I am trying to assign buttons my on my 'gameScreen' to move my character. though I am receiving an error msg saying: Error #1010: A term is undefined and has no properties.at Mainas()
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'm having trouble storing a dataprovider in a shared object. Writing the dataprovider object to my local shared object seems to work fine, but when I try to read this out of the shared object, it appears to have been transformed into a generic object. When I try to assign a local dataprovider variable to the dataprovider I've read out of the shared object, I get the following error:
"cannot convert Object@3721e6c9 to fl.data.DataProvider"
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);
I'm getting a large JSON string and decoding it into an object, i'm looping through this object to create the interface. The problem is it seems to build the interface in a random order, is this because actionscript 3 loops through the properties of the object randomly?
In Flex I can create an ItemRenderer to represent each item in the Lists DataProvider but how do I access the instance of the ItemRenderer via the DataProviders Object? Something like myList.getItemRenderer(dp.getItemAt(10));
I drag the combobox from the library and set the dataProvider through AS.however, I click the combo, the options show, I click an option but the value doesn't change. it's like I clicked outside or something, it simply stays with the same value there.
example:
[option0][v]
*clicks the v arrow*
[option0][v][code]......
I simply drag the object, give it an instance name and set a dataProvider, nothing else.
I have saved out an object using JSON.encode to a text file, is it possible to then create a new MovieClip and populate it with all of the properties from the saved file? If so how would it be done, or is there a better way
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?
