I am trying to swap two items in an ArrayCollection with this code.
[Code]...
When debugging the code I can see that curItem and swapItem are the correct objects, but when I do my first setItemAt, it replaces the one I wanted but also one that I didnt want.
I want to iterate over an ArrayCollection in Flex while there can be items added and removed.
Since i didn't find a way to use a "classic" Iterator like in Java, which would do the job. I tried the Cursor. But it doesn't really work the way i want it to be ;) So how do I do it nicely ?
var cursor:IViewCursor = workingStack.createCursor();
while (!cursor.afterLast)

I have an arrayCollection with the following structure:

the AC is defined as follows:[Bindable] private var projectErrorsAC:ArrayCollection = new ArrayCollection;
I'm using this AC in a repeater to display each error. After each error is shown, I've placed an "Accept" and "Deny" button. Once the user clicks either one of these buttons, I'd like to call a function that removes the particular error from the AC. Here's what I have so far:

I have an arrayCollection that is populating a chart. Can I bind the array items to vars that I can then modify?

{ Rating: 60 } // [2] negative

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 an ArrayCollection that is the dataProvider for a spark.components.List, which has allowMultipleSelection="true". There is a "Remove Selected Items" button which initiates the removal of all the selected items from the ArrayCollection upon being clicked.
I currently use the following method:
myList.selectedIndices.sort(ascendingSort);
// remove items, counting backwards
for (var i:uint = myList.selectedIndices.length; i > 0; i--) {
myArrayCollection.removeItemAt(myList.selectedIndices[i-1]);
}
where ascendingSort does what you expect ;). It works fine, and I know that it will always work.
However, I did take note that if I neglected the sort altogether, to my surprise the removal still worked. The reason for this turned out to be that, when the removeItemAt is called, the selectedIndices are correspondingly updated.
So my question is: Can one rely upon a removeItemAt call updating the values in the selectedIndices? or might that turn out to be different between runtimes and/or Flex SDK versions?
I would like to use the selectionMode=multiple described in the Flex docs, but with a few modifications:
1) I would like the box that the user drags over the graph to remain there until the user drags a new one.
2) In the top right corner of the box I want to display the sum of the items selected by that box.

View 2 RepliesI'm creating a facebook application in flex. I'm actually working on the friends component that shows your friends who are using the application. now, each friend has a profile image.
I created the component using a s:List element.
In the Skin Class of the element i configured the requestedColumnCount to 3, which means it shows 3 friends. i added buttons to scroll left and right in the list.
Whenever I scroll to see a different friend, for a half of a second i see no image because the List component is loading the image in order to view it.
is there a way to make the list preload all the elements so i won't have this kind of problem ?
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;

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 have a feeling I might be going about this all wrong. I have 3 objects (mask_cat, mask_dog, mask_sea_monster)on the stage and I want the user to be able to move them independently with the ol' click and drag. This is what I have:

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.

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 ?

sortField.name="order";
sortField.numeric=true;
var sort:Sort=new Sort();

I have built an image cache which is an ArrayCollection containing images. I have built functionality so that the cache can hold a max of 250 images. However, the images can be of a different size, so it's better to limit the total memory size of all images in the ArrayCollection. How I can get the total memory size of an ArrayCollection without looping through all the items in the ArrayCollection?
View 1 RepliesI have a main class ClassA that has a bunch of "normal" properties that are simple datatype like ints, strings, etc. It also has one property ("childItems") that is an ArrayCollection of ClassB.I am using an ArrayCollection of ClassA as the source for an hierarchical data provider for an AdvancedDataGrid. I set the childrenField to "childItems".
I want to display some information about the list of ClassB objects in a nested table and pie chart, an AdvancedDataGridItemRendererProvider (columnIndex = 0, columnSpan = 0, depth = 2) and point it to my custom renderer which is an HBox with the table and the pie chart in it.
In order to see what is being set, I override the "set data" function in my custom renderer and what I see is that each instance of ClassB in the ArrayCollection is passed to the renderer separately.
Here is my question: I expected the whole ArrayCollection of ClassB instances to be passed to the custom renderprovider once and not each item in the child list individually. How do I make the ADG understand that the whole property is supposed to be passed as the data to the renderer and not each entry separately? Btw, when I change the data type of "childItems" from ArrayCollection to ArrayList, the whole list gets passed and I can easily do what I want to do. But based on my understanding, ArrayList is not really supposed to be used and ArrayCollection is better or at least more common.
I have an ArrayCollection as mentioned below.
private var initDG:ArrayCollection = new ArrayCollection([
{fact: "Order #2314", appName: "AA"},
{fact: "Order #2315", appName: "BB"}[code].....
I want to populate a ComboBox with UNIQUE VALUES of "appName" field from the ArrayCollection initDG.
<mx:ComboBox id="appCombo" dataProvider="{initDG}" labelField="appName"/>
One method I could think is to loop through the Array objects and for each object check and push unique appName entries into another Array. Is there any better solution available?
is it somehow possible to get item's depth in ArrayCollection?
