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 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'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?

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 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();

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.

I have an arrayCollection of objects that extend Sprite, and have bitmaps within them. I want to display these in a list (or some other component that would allow a user to scroll through them, and see their associated data.)
When I do: myList.dataProvider = myArrayCollection
the list just shows a bunch of lines of [Object, Item] instead of the visual sprites.
Here is a simplified version of my Object:
public class myUIC extends UIComponent

Tried many different ways to get it to show up in a List, but can't do it.
I have a component where I expose the property 'questions' with the following code:
private var _questions:ArrayCollection;
private var questionsChanged:Boolean;
[Bindable("questionsChanged")]
[Code]....
In this component, I use commitProperties() to implement my logic.
I use Cairngorm and the 'questions' is in the model and hence it's defined as a source for data binding.
When the 'questions' ArrayCollection's size changes elsewhere in the application, it is not invoking the setter method in the component that is destination for the data binding.
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 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:

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>();
Can you pass an Object into flash from a button click instead of a String?
View 2 RepliesI am using PHP to save an AS3-generated XML document to my server. This works absolutely fine. Now, I'd like to be able top pass a filename along with my URLRequest under which the file would be saved.
When doing this in HTML it would be pretty easy and I would simply POST 2 seperate values, but how to do this in AS3?

is it possible to send native nested objects to flash via swfobject? i am trying this right now without luck:
PHP Code:
var flashvars = {event1:{eventid:"145",title:"event 1",toggle:["thistha","timestart"]},
event2:{eventid:"145",title:"event 1",toggle:["thistha","timestart"]},
event3:{eventid:"145",title:"event 1",toggle:["thistha","timestart"]}}

Is there a way I can pass complex objects like sprites or timers through LocalConnection? It seems like you can naively pass simple objects like String, Number, Array thru the LocalConnection. But I can't seem to send other data types.I read that you have to use the method "registerClassAlias()" within the receiving SWF file before that SWF file can accept complex objects. For example, when I attempt to send instances of Sprites or Timers, I get the following error:
"Error #2044: Unhandled AsyncErrorEvent:.text=Error #2095:flash.net.LocalConnection was unable to invoke callback sendState.error=TypeError: Error #1034: Type Coercion failed: cannot convert Object@b9210b1 to flash.utils.Timer."
How can I send complex data types or are some data types not send-able?
So i a building a categorized menu of different foods. I have a class for "categories" (buttons) which essentially will return a string "salads", "drinks", etc. I now have another class "menuItems" for items within categories and this handles sizes such as "small", "med", "large", etc. My problem now is that when i return "salads", i want to invoke an array which contains all the elements of salads, send it to menuItems which will populate the menu. So far i have both the category objects and the menu object setup. I just cant seem to be able to send the data that the category object is returning and pass it to the menu object. Both of which are added to the stage as shown below:
If there was a way that i could say add all these classes to one class so that they can talk to each other that would be great but i dont know how to do this.
I have a object, called friends, It contains the url to facebook profile picture, ie friends.friend1 = "http:// etc"; I have a swf file called, master.swf, which is passed the information to create the object through flashvars. I need to get the object OR the flashvars info to the externally loaded swf, called pageOne.swf. I have seen and tried several different methods, but now seem to give me what I need.

I'm very new to flex and to flash in general. I walked trough one of the exercises in "flex in a week", specifically the MVC exercise which talks about how to seperate the view to a different component and later on send him the data as one of his fields.
I had no problems in the exercise and everything worked BUT, when I tried to do it on my own code it doesn't work.here is my relevant parts of the code:

I created a custom button component that accepts an array as a property. I set the property as follows:
titleDims="[{Month: comboBox1.text, Year:comboBox2.text, Sales Order:comboBox3.text}]"
and I get the following error:
"1084: Syntax error: expecting rightparen before colon."
Wat is wrong with the array syntax?
I wrote a code for handling google maps in a multi touch table. On the map itself, I have a sort of button that, if touched, makes a tool bar show up. On the bar I have a slider and a button, both of them activated by touch events. My problem here is that when I touch objects on the bar, the touch event pass through the bar and it is fired also on the map below, making my map move. Uff, this is very annoying.
View 1 RepliesI've been given a video url that I want to pull into an the flvplayback component.

View 2 RepliesI have a main mxml file (flex4) and want to pass a parameter (user_name) to a component in a directory called components. When I run the program, the user_name is NOT being sent from the main to the component file. (Interestingly, if you make the component visible, you can see the parameter has been passed).
