I know that an ArrayCollection is a wrapper over an Array, but what I wanted to know is when to choose one over the other? Will the over usage of ArrayCollections result in performance?
View 1 RepliesI need to sort an arraycollection. the problem is that my array is combined from two diffrent arrays, in one the age field is called "AGE", and in the other the age is called "MYAGE".
Now I need to sort the combined array according to age but I got two fields with diffrent names. I can go through the array and change all "MYAGE" to "AGE" but i was wondering if theres maybe a way to sort the array in its current status?
i get this error when i retrieve an XML that only has 1 node (no repeating nodes) and i try to store in an ArrayCollection. -When I have MORE than 1 "name" nodes...i do NOT get an error.
TypeError: Error #1034: Type Coercion failed: cannot convert "XXXXXX" to mx.collections.ArrayCollection.
this error occurs as the line of code: myList= e.result.list.name;
Why can't ArrayCollection work with a single node? I'm using this ArrayCollection as a dataprovider for a Component -is there an alternative I can use that will take BOTH single and repeating nodes as well as work as a dataprovider?

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 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 seem to be having trouble when I am nesting 3 arrays,
var A_one:Array= [];
var A_two:Array= [];
var A_three:Array= [];
I then create a number of points and put them into array three, I do that with different groups of those groups of point and load a bunch of array threes into array twos and then I have 5 array twos and put them into array one, when I try to load a specific array three I create a variable array and do as such:
current_A_three=A_one[2[tracker.trackNum]];
tracker.tracknum is a number based on which btn I am pressing
But when I trace the value of the current_A_three array I get the error
ReferenceError: Error #1069: Property 1 not found on Number and there is no default value.
at Function/<anonymous>()
That is when I click btn one, if I clicked btn two I would get property 2, I tried playing aroudn with it, I did trace A_one[2] and did get the proper multiple arrays, but I need a spesific one.

I need to get a grip on arrays and XML data but I'm having trouble understanding how to turn xml data into useful data.I load my XML with this code:
//set values for XML data file
private var XML_URL:String = "http://www.mysite.com/media/locXML.xml";
private var locXML:XML = new XML();[code]....
Error #1034: Type Coercion failed: cannot convert []@1488bac1 to Function.
What I would like to do is omit those two last lines and then add the event listeners in a loop at the end.
I am running into some trouble adding an array into another array to create a multi-dimensional array.The code appears as below:
var slideDataArray:Array = new Array();
var slideShowDataArray:Array = new Array();
slideDataArray[0] = xmlData.SlideShowParameters.SlideShowImagesDirectory;[code]........
I am looking for a means of placing the slideDataArray into a 'slot' or value of slideShowDataArray so that I can in the end pass the slideShowDataArray as a parameter to another function.As of now, the last slideDataArray appears 11 times (the loop runs 11 times) in slideShowDataArray and the way the code is written the slideDataArray is unique every iteration of the loop.
I've got a bit that loads a big chunk of xml data about products.I push product info into an array(e.g. productArray), then add that array to another array (e.g. allProductsArray)How do I sort those arrays? For instance, if I want to sort the allProductsArray based on the info in productArray[0]?Alternatively, would something other tha an array of arrays be a better route?This loader loads the same sort of info for many different clients, so the bit to sort on will change.
View 5 RepliesSeems like in AS3, I can in theory, delare arrays that can only contain certain data types:
private var my_array:Array.<String>;
produces this error:

however
private var my_vector:Vector.<String>;
is just fine. Is there a way of making this work with an Array?

I'm trying to write a function where I can specify any amount of array, and the return value will be an array containing the contents of all of the specified arrays.I've done this, but it seems like a really slow and ugly way of doing it:
var ar1:Array = [1,2,3,4,5,6,7,8,9];
var ar2:Array = ['a','b','c','d','e','f','g','h'];
function merge(...multi):Array[code].....
Is there an inbuilt and more efficient / nice way of achieving this? The result does not need to be in the same order as the input - completely unsorted is fine.
A little explanation: Im making a random arranging number Array. So instead of using a loop and assigning 0 to first array element, 1 to second, etc.I need to make it totally random but without repeating any numbers. To do that I made a second Array that will have the same number of children to serve as a reference.Each of them will be an Object with a property "num" , wich will be its actual number, and a property "called" wich defaults to false.Like this:
ActionScript Code:
for(var i:int=0;i<vQuantity;i++){
ranArray.push( new Object() );

I've had a problem for awhile that was really odd. After some intense debugging, I realized the problem lied in setting an array equal to another array.[code] When setting one array equal to another, the values aren't copied over, but a reference to that memory is stored. So no matter which variable you change, they are both references to the same memory and thus both will reflect the changes.With other data types, this doesn't happen.I could fix it by looping through t1 and using push() to add each index from t1 into t2, but that seems a little messy.
View 7 Repliescorrect syntax for pushing variables to arrays within arrays? I have searched many threads but found nothing that exactly answers my query.I have a class (Brigade) which amongst other variables contains an array (BrigadeUnits) This is the third element.. My Brigades are stored in an array called AllBrigades. I now need to fill the BrigadeUnits array with objects of my Units class.The hierarchy I want to create is as follows:
AllBrigades (array of Brigades)
Brigade (object)
BrigadeUnits (array within Brigade object)
Unit (Object to be stored in BrigadeUnits array)
I have tried various approaches including the following, assuming that I am addressing the first Brigade in the array:
AllBrigades [0] [2].push (MyUnit);
But when I trace this I just get undefined.

I'd like to copy and paste a set of keyframes and frames at the end of the exisiting timeline... maybe several times to extend the timeline. However I've been a bit flumoxed as to how a simple chore like that is done. It does not appear one can copy the frames, then set the cursor at the end and past the frames ahead of cursor, Or do I have to create multiple layers to get the same effect by placeing them end to end down the timeline.
In the included screen shot, I'd like to copy/paste the frames on layer1 on down the time line but still on layer 1. As you can see I've started using layers to create the same effect... but is that really the way to do it?
I'm developing a Rails project that uses authlogic for authentication. And I have a part in that project that is realized with Flex, and I need to know how a user can be authenticated if he or she is logged in or not. I've set up a webservice called UserSessionService and I was trying to get the user who is logged in, but it doesn't work. If I try to get it with UserSession.find, I just get a # as the result (and therefore that's always true).
Here's the UserSessionService.rb:
require 'weborb/context'
require 'rbconfig'
class UserSessionService
def login
UserSession.find
end
end
I tried to extend the UserSessionService class from Authlogic::Session::Base, but that doesn't work either.
I trying to extends ObjectProxy class, the reason is because I want to have a Singleton of the ObjectProxy class, so I made something like
package utils
{
import mx.utils.ObjectProxy;[code]........
when I create my object uniform which is a simple object, I pass it to my UniformObjectProxy.getInstance() static method to get the instance of my objectProxy, ok so far so good.my problem is when I try to bind a property of my objectProxy instance like
_opc = UniformObjectProxy.getInstance(_uniform);
cw:ChangeWatcher = BindingUtils.bindSetter(dispatchColorChange, _opc, data.id);
the dispatchColorChange handler function is called only once an never again, I had check ChangeWatcher.isWatching() and return false meaning my objectProxy is not binding properly, if I create an objectProxy like
_opc = new ObjectProxy(_uniform);
cw:ChangeWatcher = BindingUtils.bindSetter(dispatchColorChange, _opc, data.id);
the binds works just fine, so my thinking is the problem is when I extends the objectProxy class, how is the proper way to do this
