I have two ArrayCollection and I want to merge them into one...
[Code]...
But there is an important problem, if array2 (b) has a item.month that there isn't in the array1 (a) the value is lost...
how do you merge data (coming repeatedly from server) into a filtered ArrayCollection?
The TestCase.mxml (just place it into a Flash Builder 4.6 project):
<?xml version="1.0" encoding="utf-8"?>
<s:Application
xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark">
[code]....
The problem lies in the fact, that when the ArrayCollection _data is filtered (because the Checkbox "Even" is set), then the 2nd loop in the test case (for adding new items) adds items (the "35") again and again - because it's filtered and thus not visible.
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>

View 1 RepliesIs there any way to merge cells (vertically and/or horizontally) in a datagrid? At least, for example, is there a way to show that certain datagridcolumns belong to one group. For example, I'll take three columns: column1, column2, column3. All these three should be grouped to the Category cell with a rowspan of 3 -- a "super header" if you will.
View 4 RepliesI have an application w/ 2 side-by-side pages of text. I have the VDivided box set up so the user can drag it to make one of the documents bigger or smaller.Is there a way to get the look of a VDivided box & the functionality of an Accordian, so that when the user clicks the VDivided box (or double clicks, I haven't decided) one of the documents will be hidden? (For instance, double clicking on the right-most side of the divider will hide the left document, and vice-versa)
In addition, if the user wanted to drag the divider, then they can do that as well. I don't have much, but here it is so far:

View 1 RepliesI need to merge the cells as shown in the picture:
View 2 RepliesI am looking into achieving below two features in a flex grid( or advanced grid).
1. merge column headers ( as in group just the cells in the header row ).
2. add multiple ( say 2 ) headers to the grid.
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;
if(data!=null)

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>();
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.

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?
View 3 RepliesI have a datagrid that gets its data from a webservice.When data from the webservice is retrived it calls the following function:
private function onListReg():void
{
arrRegOld = WSAutoreg.list.lastResult as ArrayCollection;
arrReg = WSAutoreg.list.lastResult as ArrayCollection;
[code].....
The intent is when I hit a update button, it compares arrRegOld with arrReg and see if any values have changes. The problem is whenever I change values on the Datagrid it changes on both the dataProvider and on both ArrayCollections.What should I do so that the binding applies only to one ArrayCollection?
