I'm creating a bordercontainer on runtime:
var bcArtist:BorderContainer = new BorderContainer();
var imgArtist:Image = new Image();
var lblArtist:String = new String();
bcArtist.id = artistXML.pk_artist_id;
bcArtist.width = 75;
bcArtist.layout = VerticalLayout;
But the last line gives this error:
1067: Implicit coercion of a value of type Class to an unrelated type spark.layouts.supportClasses:LayoutBase.
I feel it is something very easy, but haven't figured it out yet.
The layout property accepts an object of type LayoutBase but you are giving it the class itself. Try:
bcArtist.layout = new VerticalLayout();
VerticalLayout is the class. You need to create an instance of it.
bcArtist.layout = new VerticalLayout();

I am trying to develop an application in AS3. What I am really trying to achieve is to have only one datagrid and having it show, you say, three different set of datas. (the real count will be changing dynamically, and it does not matter as the problem is not relevant with this) Yes, it has to be only one datagrid because of you know, I need a compact interface.
The class "Sonuc" has three properties which are string versions of inputs from constructor. A typical "Sonuc" object is something like this.
var sonuc1:Sonuc = new Sonuc(1,1,false);
//sonuc1.num = "1"
//sonuc1.type = "1"
//sonuc1.isTrue = "No"
The reason that I have informed you about "Sonuc" class is that I wanted you to know that class was not something too complicated. And x.mxml is the test mxml where I only load the class for testing purposes.
This is what I have coded so far
public class ResultInterface extends UIComponent
{
private const desiredWidth:int = 250;
private const desiredHeight:int = 150;
private const sonuc1:Sonuc = new Sonuc(1,1,false);
public var tablo:DataGrid = new DataGrid();
public var kolonArray:Array = new Array ();
public var sonucArray:Array = new Array ();
public var currentIndex:int = new int ();
public var prevButon:Button = new Button();
public var nextButon:Button = new Button();
public function ResultInterface():void
{
currentIndex = 0;
super();
tablo = new DataGrid();
width=desiredWidth+40;
height=desiredHeight+60;
this.tablo.width = desiredWidth;
this.tablo.height = desiredHeight;
this.tablo.x = 20;
this.tablo.y = 40;
prevButon.x = 10;
prevButon.y = genislik/2 - 10;
prevButon.width =
prevButon.height = 10;
nextButon.x = genislik +20;
nextButon.y = genislik/2 -10;
nextButon.width =
nextButon.height = 10;
var referansColl:ArrayCollection = new ArrayCollection();
sonucArray.push(referansColl);
tablo.dataProvider = sonucArray[currentIndex];
var sampleCol:DataGridColumn = new DataGridColumn();
sampleCol.dataField = "num";
sampleCol.headerText = "Number";
var sampleCol2:DataGridColumn = new DataGridColumn();
sampleCol2.dataField = "type";
sampleCol2.headerText = "Type";
var sampleCol3:DataGridColumn = new DataGridColumn();
sampleCol3.dataField = "isTrue";
sampleCol3.headerText = "Is it true?";
kolonArray.push(sampleCol,sampleCol2,sampleCol3);
tablo.columns = kolonArray;
this.addElement(tablo); //**** this is the problematic line
this.addChild(oncekiButon);
this.addChild(sonrakiButon);
}
public function getNewSonuc(incoming:Sonuc):void
{
sonucArray[currentIndex].addItem(incoming);
}
public function newTablo():void
{
var newTablo:ArrayCollection = new ArrayCollection();
currentIndex = sonucArray.push(newTablo);
}
public function prev(evt:Event):void //I haven't written event listeners yet
{
if(currentIndex > 0)
currentIndex--;
nextButon.enabled = true;
if(currentIndex == 0)
prevButon.enabled = false;
}
public function birSonrakine(evt:Event):void
{
if(currentIndex < sonucArray.length)
currentIndex++;
prevButon.enabled = true;
if(currentIndex == sonucArray.length)
nextButon.enabled = false;
}
in this version, I get a syntax error "call to a possibly undefined method addElement"
I also tried having the base class as "Sprite" and "Canvas"
when I used addChild instead of addElement, then I get runtime error "addChild is not available to this class"
when I just commented the problematic line out, everything was loaded perfectly but the datagrid itself.
Note that error occurs before sending in some data (Sonuc) to datagrid.
and when I tried with canvas and with addelement, I get "Cannot access a property or method of a null object reference" with some weird functions and classes and packages.
1009: Cannot access a property or method of a null object reference.

I really need your help folks, please answer as soon as possible.
Well, I tried calling "addElement" from outside of the constructor, and it worked. However I don't know what did exactly cause this error and I know that my solution is not a legitimate one. And I would like to learn proper solution to this problem.
changes to resultInterface.as
// this.addElement(tablo); **** this is the problematic line, we have commented it out
this.addChild(oncekiButon);
this.addChild(sonrakiButon);
changes to x.mxml
public function onCreationComplete(evt:Event):void
{
showResult.addElement(showResult.tablo);
addElement(showResult);
}
I am trying to make a data grid were name and score is added to it.
I keep getting an error...
1046 Type was not found or was not a complile-time constant: DataProvider.
1080 Call to a possibly undefinded method DataProvider
and here is my coding...
var scoreArray = new Array();
D_G.addColumn("player");
D_G.addColumn("score");
enter_btn.addEventListener(MouseEvent.CLICK, saveScore);
function saveScore(event:MouseEvent):void
{
var obj:Object = new Object();
obj.player = tb_name.text;
obj.score = int(tb_score.text);
scoreArray.Push(obj);
scoreArray.sortOn("score", Array.DESCENDING | Array.NUMERIC);
var dp:DataProvider = new DataProvider (scoreArray);
D_G.dataProvider = dp;
}
That error happens when you're not including the class you want to use.
Are you using
import fl.data.DataProvider ??
You need to import the DataProvider class ;
import fl.data.DataProvider;
I've been trying to learn flex/flash programming and am working on a project where I need to populate a spinner list in flex dynamically from a string. I have a function that separates the string using "split" and now I need to populate an array list. I have been working with this stupid big for hours now and can;t find help anywhere. I keep getting the following error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at views::CommonPlaces/initApp()[/Users/twing207/Documents/Adobe Flash Builder 4.6/AmericanTaxi/src/views/CommonPlaces.mxml:30]
My code is here:
<fx:Script>
<![CDATA[
import mx.collections.ArrayList;
import spark.events.IndexChangeEvent;
var Arr1:Array;
var Arr2:Array;
var Arr3:Array;
[Bindable]
public var CommonPlacesArray:ArrayList;
var CommonPlacesData:String = new String("2133664:American Taxi Dispatch, Inc:Mount Prospect:834 E RAND RD|2133665:Walmart:Mount Prospect:930 Mount Prospect Plaza|2228885:Garage:Des Plaines:1141 Lee St|2228886:Asian Island:Palatine:1202 E Dundee Rd|2229464:Kohl's:Arlington Heights:700-856 W Dundee Rd|");
var CurrentSelect:String = new String();
private function initApp():void {
Arr1 = CommonPlacesData.split("|");
var arrLength:Number = new Number(Arr1.length);
for (var i:Number = 0; i < (arrLength - 1); i++) {
CurrentSelect = new String(Arr1[i]);
Arr2 = CurrentSelect.split(":");
//THE LINE BELOW IS WHERE IT STOPS:
CommonPlacesArray.addItem(Arr2[1]);
}
}
It doesn't seem to like the "CommonPlacesArray.addItem" line. Any help or a point in the right direction would be great. Thanks in advanced!
On another note, I am also getting the error: "Access of undefined property: data" on the following:
Here in another view I set the value for data.UserCommonReturnData to a string.
function LoginLoaded (e:Event):void {
trace(e.target.data);
var ServerReturn:String;
ServerReturn = new String(e.target.data);
data.UserCommonReturnData = ServerReturn;
navigator.pushView(CommonPlaces, data);
}
and here I try to pull it back:
var CommonPlacesData:String = new String();
var CurrentSelect:String = new String();
//The next line gives the error:
CommonPlacesData = data.UserCommonReturnData;
Any idea??
You never construct CommonPlacesArray, you just declare it.
var CommonPlacesArray:ArrayList = new ArrayList();
If you check the Array List API you can also clearly see it has a constructor that accepts an array, meaning you can copy the data to it without having to iterate over it yourself.
for instance if a string is
data = "success=0"
or
data = "success=1®istration=20";
how to parse all variables into URLVariables class object.
var urlVars:URLVariables = new URLVariables(data);
or
urlVars.decode(data);
If i remember right this will solve your problem.
var urlvar:URLVariables = new URLVariables(data);
I have a variable named "type". And I want to instance an object with the name of the value of type. Here is an example:
var myObjectName = "ball";
var object = new ball(); //Except I want to use the value of myObjectName.
I believe this used to be easy with AS2 when using _global, but I'm not sure how to do it in AS3?
Any help?
First get the class object with flash.utils.getDefinitionByName(), then instantiate that object:
var myClass:Class = getDefinitionByName(myObjectName) as Class;
var object:Object = new myClass();
