I have an arrayCollection that is populating a chart. Can I bind the array items to vars that I can then modify?
private var ratingAC:ArrayCollection = new ArrayCollection([
{ Rating: 10 }, // [0] positive
{ Rating: 20 }, // [1] neutral
{ Rating: 60 } // [2] negative

I 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?
I am using flex SDK 3.5. I have model.as and in it i have an ArrayCollection (name it arr_mod) which is Bindable.
From my mxml i link to this arr_mod in three places:
1) in DataGrid i set dataprovider={arr_mode} ...
2) in Button i add new item to the arr_mod this way: mx:Button .. click = "{arr_mod.addItem(new Item)}"
3) in textBox i want to add mx:TextBox text="{mySpecialCounterFunc(arr_mod)}"
note that in the Script of mxml arr_mod is Bindable as well as in the class definition in model.as
The problem is, that when clicking on button, mySpecialCounterFunc is not called! it should be called, since i use {} and this should listen to changes in arr_mod (a change that was made in the button should cause a new item to be added.. and than the listener to respond). While The DataGrid is updated correctly! By the way, if i change arr_mod to simple String or Int it works.. i.e. mySpecialCounterFunc is called Why??
I am trying to bind an ArrayCollection result coming in from the server to my DataGrid
created dynamically in AS. The result data is not getting Displayed in the Grid.
var dg:DataGrid = new DataGrid();
dg.width=650;
dg.dataProvider=someArrayCollfromServer;
I am adding the dgColumn as runtime based on some data from a XML and it is the same as defined in below static format. But if I use the same code and create the DataGrid as a Flex Component as below, it works fine.
<mx:DataGrid id="dg" width="100%" height="100%" dataProvider="{someArrayCollfromServer}">
<mx:columns>
<mx:DataGridColumn dataField="Value" headerText="Value"/>
<mx:DataGridColumn dataField="Code" headerText="Code" />
</mx:columns>
</mx:DataGrid>
This works fine. Is there some functionality or implementation different as far as DataGrid is concerned in Flex and AS.
I have a somewhat complex parent/child hierarchy object that I need to display in a tree format that dynamically updates. To pass it into the tree as a dataprovider I convert the top level parent into an Array and then into an ArrayCollection. The problem there is if anything changes in the hierarchy the tree isn't dynamically updated unless I regenerate the dataprovider.
EDIT: I didn't have much code shown so I just tried to include the skeleton version of how everything is being used below, the tree works fine and even when I remove/add nodes the changes are evident but the vertical scroll bar isn't updated(doesn't resize) and if I scroll the tree will get out of whack and may display whitespace at the bottom of the tree where the item was just removed.
I tried just a plain bindable ArrayCollection test object with multiple levels and it updates properly so I think my tree is fine it's just how I'm trying to bind the dataprovider that I'm having the issues.

I have an ArrayCollection containing bindable objects. I would like to access them in multiple places like below (there's only one label for clarity). How can I achieve that?hould I write some kind of wrapper for ArrayCollection dispatching special event (which?) catchable by Flex event mechanism.

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 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?

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'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"?>

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.
Is it possible to specify MXML-esque "binding strings" in ActionScript?For example, I want to be able to do something like:

i am trying to load vars from a text file into a load vars object.
var kitchentext = new LoadVars();

but i am having trouble doing this.
i have a textbox called displytext.
_root.displaytext.text = kitchentext.name;

I have a project underway where I am making an interactive game. It is a personal character creator game and I need Actionscript 3 help with this.Something similar here:http:[url]....
I have tried already with toggling visibility and 'gotoAndStop()' to make items appear over other items when the corresponding button is pressed, for example, when the user tries out different pants/shirts on their character.
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.
How to make list items as tool tips for combo box items?
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 ?
im having some dificulties in the combobox of Flex 3, after defining the dataProvider and filling the combobox, how can i remove the items in the combobox later (without removing items in the dataprovider)? if i set the provider to "" or null, the items in the combobox are still there
View 1 Replieshow to get my CollectionEvent to work, and I seem to be able to see the problem, but I am not sure how to get it to work properly.
In my actionscript, it seems to only tell that event.items.length is 1, while I am calling my array collection from the HTTPService, and I have tested the length of my Array Collection, which seems to be accurate. What I tried to do is to use that number in the CollectionEvent function, but that does not work at all.
Attach Code
private function onChange(event:CollectionEvent):void{
for (var i:int=0; i< event.items.length; i++) {
Alert.show(event.items.length.toString()); //This always gives me 1 when I have 12 items

My application uses fx tag in which it loads some xml. I want to create the xml name by binding, but I get an error that Data binding expressions not supported with attributes processed at compile time.

I have this variable in Model class:[code]I've used BindingUtils to get notified when the XML changes:[code]Function onChange gets triggered when I assign an XML to the variable, but not when I change some attribute of the XML: Model.getInstance().someXml.@attr = "newValue";
View 1 RepliesI'm currently looking at ways to externalise all text in my flash applications into external xml files (for translation purposes). Basically, all copy in these applications has to be in two languages (English and Welsh).
At the moment, I'm just looking at a structure whereby the name of each TextField instance is the same as a field in the XML, which then has two fields (<english> & <welsh>) inside with the relevant text. The XML will be loaded in and then looped through applying the text to the textfield of the same name in the current language. There will obviously need to be some error-handling with regards making sure the names match up but this can only be done at run-time.
This seems a bit, I dunno.. lose? Is there are way of creating a better structure or system that'll be a bit less reliant on accurately naming various things so they match?
I actually got it to show up in the dynamic text box, but its also displaying my xml and css tags(The XML file structure). I know the xml and css files both work after testing them in my browser. My XML file only has one node. Below is my AS3 code:
Code:
var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE, onLoadXML);
loader.load(new URLRequest("content.xml"));
function onLoadXML(e:Event):void {
var xml:XML = new XML(e.target.data);
//trace(xml)
textBox.text = e.target.data
}
I just need it to read the content and follow the css code that's been attached to it.
I'm trying to make a td game for fun and I need to make function to build towers and if I want to build the second tower it changes the first one... But I thought if i could change the name of the first tower's name when it builds to other var and it should be fine, but the problem is that those 2 towers will shoot together or something, so is there a way to bind functions to movieclips that are created with actionscript (addChild(Name))?
View 1 Repliesfirst one shows playheadtime of videodisplay and another is also used for same purpose. the difference is that when we are in add mode(decided from a flag variable) both should show current playheadtime using binding. but when we are in edit mode(again decided from flag) the latter label should remain static, to be more specific, the value retrived from database.how can I do that using actionscript. I tried ChangeWathcer but I found it a bit tricky. Is there any other simpler way or am I missing something. following is my code.

I want to load key/values configuration pairs stored in XML file. To bind a collection of data i know i need to use the ArrayList class, but the problem is that i want to be able to bind the loaded values using their corresponding keys and not by their indexes in the ArrayList object. For example i want to be able to do this :

So the question is how to bind the key/value pairs loaded form XML. I don't want to go manually set variables, i want to bind them so when they are loaded the are set automatically. Did anyone had to do something like that ?
I have a flash app using the flex framework - I would like to bind a display object textField with data from my dataModel.
How do I do this without the flex binding brackets "{ }"
I'm having some troubles with binding data. I have an application that contains a viewstack of components. Let's say I have comp1, comp2 and comp3 inside the viewstack. Each component, has its own data class --> comp1Data.as, comp2Data.as and comp3Data.as. All values in each component are binded to the corresponding data in it's data object.
A click in a control in comp1 leads to comp3, the same goes for comp2. Clicking a control in comp2 leads to comp3. When going from comp1 to comp3, comp3Data.as is initialized and and comp3 displays the binded values. When going from comp2 to comp3, comp3Data.as is also initialized but the binded values are not displayed...
