Flex :: ArrayCollection Objects To String - "for Each" Loop
Oct 2, 2009
This is related to other question. But never mind it. I've fixed part of it. I have a DataGrid, its data provider is a ArrayCollection, and i want it to parse all itens in it (Object Type) to a String. For that I've done a "for each" loop, it manages to get the Object and its values, but if i have more that one object it only gets the last object, don't know why.
First i will show how these items are added to the ArrayCollection, that way you will understand the rest much easily. In the Main Application i have the ArrayCollection:

I am trying to get the contents of an arraycollection to print out using my debug function (which takes a string). Anyone know how to do this? I would like it would be rather easy but can't seem to find a way...I get the word "Object" printed a lot of the time.

I'll show you the function first.[code]As you see, the order i put the items in the ArrayCollection is Areal, then Verdi (area, value)When i loop through the collection later, the order changes. Now it is Verdi then Areal (value, area).Does anyone have an idea of what might be the problem?It really ruins things when I pass it over to a PHP-script for table-making in html later.(I have several different dynamic DataGrids that differs in size and "values", so I can't really point directly to f.ex "Areal" in my PHP-script)And by the way, does anyone know how i can remove that pesky mx_internal_uid?

Is there any built in functionality to convert an ArrayCollection to a jagged string array? I have an Arraycollection of objectproxies that I get from a SOAP webservice (asp.net datatable) that I modify and want to send back.

the applicable differences between an ArrayCollection and a Vector in flex? I'm unsure if I should be using one over the other. I saw that Vector is type safe and that makes me feel better, but are there disadvantages?
public var ac:ArrayCollection = new ArrayCollection();
versus
public var vec:Vector.<String> = new Vector.<String>();

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

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 have a string like this:
var tempSting:String = "abc@abc.com;xyz@xyz.com"
I want to add this String into the ArrayCollection. And the above String should be divided by mail id and remove the ; symbol and need to add asArrayCollection
tempAc:Arraycollection = new ArrayCollection{abc@abc.com, xyz@xyz.com}
add the split String into the ArrayCollection.

I am currently using the latest verion of Adobe Flash Builder to create a Mobile Application. For the application one feature is to allow the users to bookmark content an this is done by storing the id of the object to be Bookmarked into an SQLite db on the device. This part has been done successfully and they are stored fine.
Now what I want to do is to pull back the bookmarked id's from the database and pass them to a WebService call which needs to be made to an External Database. When I retrieve the Bookmark id's from the local database they are contained within object, I now need to find a way to take the id's from the database objects in the ArrayCollection and store them in a new array that will be passed to the WebService, as the webservice is expecting an Array of Int's and not Objects. Below is the code I created to see if the object items are within the array list of objects:
private function loop():void
{
var index:int;

public function create():ArrayCollection{
var index:int = 0;
var data:ArrayCollection = new ArrayCollection();
[Code]....
originalData is the original state of my data from database. data is a copy of originalData used to be manipulated as the provider for my List component. There's a button I use to call the create() function above, that would mean, I want to revert all changes in data, and go back to everything I have in originalData.
But when I debug my function, originalData has all the changes made in data.
When I use
list.selectedItem.thing = "new string";
is supposed to modify data[index].thing, because data is my List.dataprovider. but it changes originalData[index].thing also and this collection wasn't used for anything, except for creating a copy of itself!
I don't know why this happens. I didn't know how to phrase this behaviour as a google query.
This has consumed more time than its functionality is worth.
EDIT:
I've also tried this, but it doesn't work:
public function create():ArrayCollection{
var index:int = 0;
var data:ArrayCollection = new ArrayCollection();

But I keep getting an "Error #2030: End of file was encountered." This is (probably) because the class I'm serializing is too big for the "String" object type in AS3. Is there a limitless object for storing an array of characters (or better yet binary), or am I going to have to make my own class? (like one with an array of strings)

I was wondering if this concept is doable:
Scenario:
4 areas on 1 stage which are quite similar (eg webcamconference, each area has the same functions)
Buttonobjects are numbered(eg area 1 has playbutton1,mutebutton1,namebutton1,namelabel1, etc)
every area gets a close-Button which closes/shuts down the area.(close1,close2,close3...)i want to archive the following:
if(close1.isPressed){
function invisall(1);
}[code]....
this should do the trick via dynamic Nr at the end of each default button(eg playbutton)
but ofc
"playbutton1"._visible=false;
doesnt work because playbutton1 is still a String.how can i take the String as a Buttonname /ButtonObject? do i need to write an new function? this would destroy the purpose of less code. for now i will split the area into frames that i put on the stage.

I have a advanced datagrid and populating some data by using arraycollection. And i am filtering the arraycollection, the arraycollection index got changed.
Arraycollection:- [0] - name: abc
[1] - name: hello
[2] - name: hello1
[3] - name:hai
after filtering the arraycollection as 'hell' , the array collection is displaying like the below:
Arraycollection:-
[0] - name: hello1
[1] - name: hello
Can i know the reason why the index got changed after filter it?
* no server side code for filtering. it is only flex side filtering.

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;

In Flex, it's easy to convert the XML to Object and to ArrayCollection by using var decoder:SimpleXMLDecoder = new SimpleXMLDecoder(); decoder.decodeXML( xml );
But is there a good way to convert ArrayCollection to XML.

I currently have an arrayCollection in Flex and I want to sent it to PHP (Zend_AMF). According to the Zend_AMF wiki, sending an arrayCollection over directly will force Zend_AMF to cast the arrayCollection as an object which is no good. I'd rather have an array of my models. I assume the best way would be to convert the arrayCollection to an array in flex and then send it over. Is this true, and if so how would I do that in Flex 3? If you have a better recommendation,

Context:
I use an ArrayCollection object as follows:
1) Number of elements is fixed.
2) Elements are inserted at a given position, based on some order.
Can I set the max size of the ArrayCollection? Will fixing the size improve the performance, as elements keep getting inserted into this collection?

After applying a numeric sort to my dataprovider(Array Collection), I can not reorder the items via a tilelist. Do I need to remove the sort from the arrayCollection. If so, is it just a case of setting collection.sort = null ?
var sortField:SortField=new SortField();
sortField.name="order";
sortField.numeric=true;
var sort:Sort=new Sort();
sort.fields=[sortField];
