I new to flex, I have a class shown below:
public class Items extends Object
{
public function Items(){
super();
}
public var name:String;
public var count:int;
}
How do I create an ArrayCollection of type Items?
I am developing one small demo application. In that i have created one action script class named City which has two fields. cityId, cityName and i have also mapped this class with my backend java class City using tag RemoteClass. at Java side City class contains same fields as in actionscript city class.
[Code]...
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?
View 1 Repliesthe 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 would like to create a new AC instance with a dynamic variable which is nca1, nca2, etc. Without define using hardcode variable name, it is possible to do that in a loop?
View 1 RepliesI'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 am using Flex 3 and make a call through a RemoteObject to a Java 1.6 method and exposed with BlazeDS and Spring 2.5.5 Integration over a SecureAMFChannel. The ActionScript is as follows (this code is an example of the real thing which is on a separate dev network);

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:
[Code]...
<fx:Array>
<fx:Object name="Jodie" country="UK" language="English"/>
<fx:Object name="Kate" country="USA" language="English"/>
<fx:Object name="David" country="France" language="French"/>
</fx:Array>
But I want to do this dynamically from results that I get from a DB.I have an attendance program and I want the object's names to be "Date","In","Out" and the values to be, of course from the results that I get.
I have created a Component class and it's working fine .I want to pass an ArrayCollection of Objects to the Component .I have read in many articles , that we should use [Bindable] to make an ArrayCollection of Objects .What are the ways can we achieve that ?
View 2 RepliesI 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;
[Code]....
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();
[Code].....
When I try to do this in an AS CDATA block, it tells me I can't have a class declared within a class (the MX:Application itself). Makes sense. But where and how do I do it?

I am working with google map api ... http:[url]..What i want to do is to take up all the steps of direction, and place them in a datagrid.but the problem that the google map api provide description on in HTML format. and then i put this steps data in my flex datagrid, it shows up all the html tags in it too, including with the data.Can there be some way i can do this, without the html tags.My code for the google maps look like this :
private function processTurnByTurn():void {
var stepText:String;
var stepMarker:Marker;[code]....
This is the function to create the step ArrayCollection for the datagrid and the datagrid code looks like this:
<mx:DataGrid width="100%" height="100%"
dataProvider="{StepArray}">

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 want to create a flash movie which firstly loads a selection of images/objects into a portion of the frame. After this is complete, the user can then drag these objects onto another area and the object will be created where the user has chosen. The user can then drag another instance of the ojects onto the area.
For example, there is a background of a lake in one area. A selection of boat pngs are loaded in an area below the lake. The user can drag these boats and place them on the lake. They can drag a boat multiple times if they wish.
Why do we need to create objects like Sound Objects, Date Objects and Text Objects before we load them? And what are the advantages of using objects?

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:

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,
View 1 RepliesIs there any way in Flex where in we can sort an arraycollection based on strings .I have a dataprovider with strings like "Critical" "High" "Medium" "Low" where in I need to sort it in such a way that I need Critical to be displayed on the top and next High , Medium and Low follows.
View 1 RepliesContext:
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?
is there any way to use ArrayCollection (from mx.collections.*) in Flash CS3/4/5? How?

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];
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.
