Flex :: Cannot Access ArrayCollection's Children In Datagrid
May 22, 2009
I've got a Flex 3 application with an HTTPService returning an Atom feed. I catch the result from it and store it in an arrayCollection which is then the provider of my Datagrid. I have no problem accessing the data from the "first-level" of my Array, but cannot go under it. Not very clear, so here is some code:
My XML [part of it]:
<entry>
<title>Test 2</title>
<id>http://collaboration.*****.com/collaboration/messaging/feeds/****/todo//7D6637D3E86B3ED3C12575B***8479</id>
<link rel="alternate" href="notes:///C12575B4004***8
[Code]....
The "title" column shows the data correctly, but the status column is empty ! When I launch my app in debug mode, I can see that my notesArray has the correct format and I can access todo -> status with the value..

I have an ArrayCollection with following structure (when viewed in debug mode):
[0]
- [0]
-- src
- [1]
-- src
src is the path to an image.
I need to get all of the src's out of the arraycollection. However because of the first (unnamed) node I can't take them in. I've tried ArrayCollection[0].children and save the result in another ArrayCollection, however the new ArrayCollection has 2 Objects in it but no 'src'. There are just 2 null objects
firstArrayCollection is filled with the data as described above.
secondArrayCollection.addItem(firstArrayCollection[0].children);
When viewing the content of secondArrayCollection i see following structure (and data):
[0] null
[1] null

I'm a bit new to flex and cannot get my head around this problem.
I have a string list path.
path 1 - "one/two/three"
path 2 - "one/two/four"
path 3 - "five/six"
i need an advanced datagrid to show a tree structure like so
one/
...two/
........three/
............four
five/
.......six
but i want to achieve this dynamicall with arrays, objects, or arraycollection (as applicable).I need to loop through each string path using string methods which isnt a problem but how do i create "DYNAMIC" (depth) children?

I have a Canvas which has many components inside it and those again, have many components inside them.
getChildren() returns only the top level children. What is the best way to retrieve all the children (children of children of children and so on).
Well, I sorta know how to do this by iterating through the children, but the code is really messy. I'd prefer to use a nice recursive function. Has anyone written this before? Or is there a Util class to do this?

I am trying to bind an ArrayCollection result coming in from the server to my DataGrid
created dynamically in AS. The result data is not getting Displayed in the Grid.
var dg:DataGrid = new DataGrid();
dg.width=650;
dg.dataProvider=someArrayCollfromServer;
I am adding the dgColumn as runtime based on some data from a XML and it is the same as defined in below static format. But if I use the same code and create the DataGrid as a Flex Component as below, it works fine.
<mx:DataGrid id="dg" width="100%" height="100%" dataProvider="{someArrayCollfromServer}">
<mx:columns>
<mx:DataGridColumn dataField="Value" headerText="Value"/>
<mx:DataGridColumn dataField="Code" headerText="Code" />
</mx:columns>
</mx:DataGrid>
This works fine. Is there some functionality or implementation different as far as DataGrid is concerned in Flex and AS.

I use this arrayCollection to populate a Flex 3 Datagrid. I'd also like to use this arrayCollection to populate a comboBox with the Name node.
In the arrayCollection, I've got the Name listed twice. I've got two rows in the Datagrid.
If I set the ComboBox's labelfield to Name, then the Name will be listed twice in the ComboBox menu. Is there a way to use this arrayCollection and have each Name listed only once in the comboBox?
I can always make another loop and array collection for the Name, but I was wondering if there were a better way.
var i:uint;
for (i=0; i<myArray.length; i++){
myDGArray = [

i have a problem using the itemRenderer functionality. When using an ArrayCollection the visible Data in the DataGrid using the itemRenderer will be rendered just fine. But if i start scrolling the entries are repeating in the cells using the renderer. The cells are not filled with date according to the id. What mistake i'm doing here.
I read a lot of the explainations like:

here is the code for the set data function (itemRenderer is extending HBox):
override public function set data(value:Object):void {
_data = value;
if(data!=null)

I'm using FlashBuilder 4 and trying to create a dropdownlist that populates a datagrid. The functionality is fine but my data is being chopped up too much. Currently every since "nepName" tag in my XML file is showing up in my dropdownlist (which makes for many duplicates of the same names) and only shows the data associated with that nepName tag. I want each nepName (by name ex. Barnegat Bay National Estuary Program) to display only once in my dropdownlist and populate my datadgrid with ALL the data in the XML file that is associated with that name

Does anyone know if its possible to access children elements in a SWC? I have created some MC's and inside of some of these MC's I have some dynamic textFields. I export the content to a SWC and load it into my Flex project. No problem loading it or accessing the parent elements, they display fine. But I want to access the textfields nestes in the MC's and modify the text. When I debug the app, I can see the textfields as child elements. It's typed as a TextField and the Instance Name is the same as input in the Flash IDE but I cannot access it. When Flex compiles it throws an error saying it doesn't recognize the method. I've tried to insert actionscript on the timeline, linked external classes and nothing can be accessed.

I have a Sprite called pageContent. Inside pageContent are 12 more Sprites with unique names, a couple of Buttons, and some TextFields. Inside each of the 12 Sprites I have either one or two TextFields and one TextInput. My question is, since they are children inside a child of pageContent, how can I access them? Here is how I am trying to do it:
[Code]...
In my mind, this should totally work. But surprise, surprise, it doesn't. I have debugged it and it works fine for the first two lines, but when it tries to get numChildren of a Child of pageContent (line 3), I get this error: PHP Code: 1119: Access of possibly undefined property numChildren through a reference with static type flash.display:DisplayObject.

I'm new to Flex and am using TileList bound to an ArrayCollection. The array collection is empty at load time, and then updates with the results from am HTTPService call. The problem is that the item renderers aren't being rendered as expected, I'm guessing because there was no data when they were first rendered at load time. Here's simplified example:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" >
<mx:Script>

I am stuck in a problem working on Flex datagrid, in an AIR application. How can I access a specific row in datagrid in Flex. I am not talking about the selectedItem or any particular record of dataProvider of datagrid. What exactly I want to do is I am showing some files data (name, description etc.) on a datagrid, and the data of these files comes from an array which is the dataProvider of the datagrid. Now when these files are being uploaded one by one to the server (using a webservice), I want to show a ProgressBar on, say, "Progress" column in the datagrid. How can I access this column for a particular row in datagrid i.e. current file being uploaded.

I have a Datagrid with an ArrayCollection as DataProvider, the arrayCollection is partially generated by a remoteObject call, the dataprovider seems to works at least until I try to edit the field...By the RemoteObject I only receive an ArrayCollection with the field ip, but the datagrid looks for the fields ip, check and save...If I add/edit this new field it works, but only under particular condition
The DataGrid:
<s:DataGrid id="datagrid" left="10" right="10" top="136"
dataProvider="{listaIPCheck}" bottom="10" requestedRowCount="4">
<s:columns>[code].....
This code always work in the 3 points, so at the end of the call the ArrayCollection is always filled with the new values, but the datagrid refresh the items only in point #1 and #2.

I am currently trying to use the new approach of using FlexGlobals to access an ArrayCollection that I have on the Default view of a mobile application I am developing. Below is the code that makes up the creation and population of that array on the Default view which happens as soon as the app is initiated:
private var ids:ArrayCollection = new ArrayCollection();
private function loop():void
{
var index:int;
[Code].....
I could only assume that the ArrayCollection I had created in my default view has no value once I navigate away from it. this as there seems to be next to no documentation on how to do these types of things with FlexGlobals?
