Problem in arraycollection?

Hi,
I given an arraycollection as a dataprovider to a datagrid which was with some itemrenderers.
while retrieving the saved data from the grid i am copying some columns like
arraycoll[3]['name'] = 'saome name';
when i am assigning some value to a particular row item in the dataprovider arraycollection,
all the rows are updating with the same name.
for example: if an arraycollection has 3 items like
arrcoll:ArrayCollection = new Arraycollection([
{name:'sample1' id:1},
{name:'sample2' id:1},
{name:'sample3' id:1}
when i want to update the second name i.e.sample2 with sample4 and i assigned that value like
arrcoll[1]['name']='sample4';
all the items are effecting like
{name:'sample4' id:1},
{name:'sample4' id:1},
{name:'sample4' id:1}
So how can i update a single item in an arraycollection.
please provide me the solution
Regards
D.Mahesh Babu

Here i am populating an arraycollection with the data which is coming from the database.
In this arraycollection i want to copy some items into the other arraycollection which is a dataprovider
to a datagrid.(I dont want to copy the complete row, but some items in a row)
so when i am copying like
for(var i:int=0;i<arrcoll2.length;i++)
arrcoll[i]['name']=arrcoll2[i]['name'];
So the problem is after the above loop was completed, all the rows in the arrcoll is filled with
the last row items of arrcoll2.
Another problem is in the datagrid i used an itemrenderer of richtexteditor to edit that cell.
so when i edit that cell and save the edited data to the dataprovider like
data[listData.dataField] = 'editedCellData';
all the cells of that column are updated with the same data.
So please provide me the solution. If u want anymore details please reply me soon.
Thanks

Can anyone solve this simple MVC problem with ArrayCollection

I have very simple application trying to understand how to apply MVC without any framework. There are quite a few exemples on the net but most do not deal with complex data.
here is my application with 4 files: MVCtest.mxml, MyController.as, MyModel.as and MyComponent.as
first the Model MyModel.as
package model
import flash.events.Event;
import flash.events.EventDispatcher;
import flash.events.IEventDispatcher;
import mx.collections.ArrayCollection;
[Event(name="ArrayColChanged", type="flash.events.Event")]

And finally here is the PHP script.
<?php

var $_explicitType = "valueObjects.myVOorDTO";
public $myid;
public $mystring;

public $myreal;

      $row->myinteger = $obj['myinteger'] + 0;
      $row->myreal = $obj['myreal'] + 0.0;
      $row->mydate = new Datetime($obj['mydate']);
      array_push($results, $row);
    return $results;
?>
My understanding as to what is going on is: (1) on creation complete the application launch the initialise() function of the controller (2) this function starts the remoteObject which get the data (3) once the results arrive the resultHandler store the data into the ArrayCollection of the model ***this does not work*** (4) even if part 3 did not work, the setter of the ArrayCollection in the model send an event that it has been changed (5) the controller receive this event and assigns the ArrayCollection of the model as the dataprovider for the datagrid in the compoent.
Of course, since the ArrayCollection is null, the application gives an error as the dataProvider for the datagrid is null.
What is missing in this application to make it work properly? I believe this is an example that could help a lot of people.
Even if I change the setter in the model to _myArrayCol = ObjectUtil.copy(value) as ArrayCollection; it still does not work.
Also, it seems that the remoteObject does not return a typed object (i.e. myVOorDTO) but rather generic objects. I am usually able to make this works but in this particular application I have not managed to do it. Again what's missing?
Thanks for any help with this!

Arraycollections Problem

Hi i'm having some problems with Arraycollections. here is what my intention is and what i'm doing
What i want: I want to send some information from the flex ui to a java class . and save this info in a data base.
What i'm doing:
I'm packing the info into a Arraycollection(it consists of an 2-D integer array and a String array).
Sending it to a java class using remote object. I'm using flex.messaging.io.ArrayCollection package to use Arraycolelction to recieve that data in java class
Problem: I want o extract the integer array and String array from that ArrayCollection so that i can use it to store them in DB.
Am i doing anything wrong?? Is there any alternate way like storing the whole Arraycollection as it is in DB

Hi Bhasker,
thanks for u r reply. Here i attached screen shot of my server "data.result".
My proxy varaible contains
My object varaible "obj" contains
After parsing the result my arraycollection contains, (i mean after converting Object to Array to ArrayCollection) the below information. For information Pl find the attached arraycollection.png image. In the attached image my arraycollection name is "users".
Here i pasted the code that i used to convert "ObjectProxy" to "ArrayCollection"
var proxy:ObjectProxy = ObjectProxy(data.result);
            var obj:Object = proxy.object_proxy::object;
            var arrycoll:Array = ArrayUtil.toArray(obj);
            model.users = new ArrayCollection(arrycoll);

How to update ArrayCollection at runtime?

Am facing some problem with arraycollection..
am having an arraycolelction like this...
var dpHierarchy:ArrayCollection = new ArrayCollection([
{Region:"Demand1"},
{Region:"Demand2"},
{Region:"Demand3"},
{Region:"Demand4"}]
now what am looking for is.. how to update this
arraycollection at runtime using actions script?
i need to update this array colelction something like this...
var dpHierarchy:ArrayCollection = new ArrayCollection([
{Region:"Demand1", Year:"2008"},
{Region:"Demand2", Year:"2008"},
{Region:"Demand3", Year:"2008"},
{Region:"Demand4", Year:"2008"}]
How to add Year field in to existing arraycollection like
shown in about example..
thanks in advance
Pratap

There are two ways you can do this. One would be setting it
straight like this.
private function updateDP():void {
dpHierarchy[0].Year = "2008";
This will also make it so that every other item in your
ArrayCollection has the Year identifier however nothing will be
filled in for the values. The other way you could do this would be
to user setItemAt which would look like this.
dpHierarchy.setItemAt({Region:"Demand1", Year:"2008"}, 0);
which essentially does the exact same thing except your
setting all the properties of that item instead of just adding the
identifier Year.

WebService, HttpService, namespace

I've happily been using htttpService calls, connecting to my
own PHP scripts without many problems. But I now have to use
services provided by a third party. The services can be used with
either webService or httpService, but all return xml data with an
included namespace. (xmlns="
http://www.example.com/api").
This seems to make life difficult, and I suspect I'm missing some
magic ingredient. My biggest problem is populating a datagrid with
the returned data.
1. Problems using ArrayCollection
If I use the webService call, and *don't* use the e4x
resultFormat, I can populate the grid by setting the dataProvider
to service.operation.lastResult. This works OK.
If, instead, I set the dataProvider to an mx:ArrayCollection
object like below, it doesn't work. No data appears in the grid.
(This method is illustrated in a number of examples in the docs.)
<mx:ArrayCollection id="statesAC"
source="service.operation.lastResult" />
But if I add an mx:Binding element, and point this to the
ArrayCollection, it works.
<mx:Binding source="service.operation.lastResult"
destination="statesAC" />
<mx:ArrayCollection id="statesAC" />
I should be happy that this works, but I'd be more
comfortable knowing why the middle approach doesn't, especially as
the docs seem to push this as a preferred approach. Any thoughts?
2. Problems using XMLListCollection
This is more troubling, as I'd prefer to use an
XMLListCollection to populate the grid.
I've had no success using the webService approach. I can't
get any of the above techniques for ArrayCollection to work for an
XMLListCollection. No data appears in the grid.
I've had more success with httpService and handling and
converting the XML directly in the service's result event. But this
also is not straightforward:
-- I have to set a namespace, using either "default xml
namespace = ...." or "use namespace ...". Without doing this, I'm
unable to extract an XMLList from the returned XML. (The XMLList is
used to make the XMLListCollection for the DataGrid.)
-- It seems that the DataGrid's dataField properties are not
recognised when a namespace is being used, even when the
above-mentioned namespace settings are in place. A labelFunction
has to be used, but even that is not straightforward.
Assuming a property name of "Name", this won't work for a
column setting (no data appear in the column):
<mx:DataGridColumn dataField="Name" headerText="Name"/>
This will work:
public function gridFunction(item:Object,
column:DataGridColumn):String {
return item.Name;
<mx:DataGridColumn headerText="Name"
labelFunction="gridFunction"/>
But this won't (although it works with XML that has no
namespace set):
public function gridFunction(item:Object,
column:DataGridColumn):String {
var fieldName:String = column.dataField;
return item[fieldName];
<mx:DataGridColumn headerText="Name"
labelFunction="gridFunction"/>
The labelFunction approach, although it displays data, still
leaves isues with sorting. I'm sure this is not how things are
meant to be.
Any insights as to how to make this easier would be
appreciated, especially with regard to working with
XMLListCollections.

From the webservice example.........
http://www.cflex.net/showfiledetails.cfm?ChannelID=1&Object=File&objectID=582
Instead of using:
default xml namespace = "http://www.webservicex.net"; to
define the default namespace of the Webservice,
You can automatically find the namespace of the Webservice
and set it to your default namespace in your result handler. Then
you would be able to use multiple webservices in multiple result
handlers.
[Bindable]private var xmlResult:XML;
private var wsDefaultNS:Namespace;
private var wsDefaultNS:Namespace;
private function onResult(oEvent:ResultEvent):void
xmlResult = XML(oEvent.result);
wsDefaultNS = xmlResult.namespace();
default xml namespace = Namespace(wsDefaultNS);
I have only been able to get data from webservices into a
datagrid by the labelfunction. I don't know of another way.

Binding To a Propery - Inside an ArrayCollection Problem

I'm trying to make an editor where users can select an editable item from a list (each item in the list might be a different type of editable object). When the user selects an item from the list its editable properties show up in a panel with a suitable item editor.
The problem I'm having is I don't want all item properties to be editable and I need to be able to specify what type of editor should be used e.g. TextInput, ColorPicker or custom editor.
I thought about creating an EditableItem objects which could have an ArrayCollection called editableItems which holds what can be edited and what type of editor to use in a EditConf object:
package
    [Bindable]
    public class EditConf
        public var value:*;
        public var editor:String = "DefaultEditor";
        public function EditConf(value:*, editor:String)
            this.value = value;
            this.editor = editor;
Inside the EditableItem would look something like this with an ArrayCollection holding the EditConf objects.
package
    import mx.collections.ArrayCollection;
    [Bindable]
    public class EditableItem
        public var label:String;
        public var colour:uint;
        public var nonEditableVar:String;
        public var nonEditableVar2:Boolean;
        public var editableItems:ArrayCollection;
        public function EditableItem()
            editableItems.addItem(EditConf(label, "TextInput"));
            editableItems.addItem(EditConf(colour, "ColorPicker"));
The problem with this is when you assign the editor - say a TextInput to edit the value "label" from the editableItems ArrayCollection it updates the editableItem ArrayCollection but not the variable "label". I thought the ArrayCollection would just hold a pointer to "label" so it would update the variable but no such luck.
Does anyone know of a better way to create the application above or why the binding does function as I expected?
Many Thanks

It sounds more like an architecture problem. If I had a problem like this, I would have a model class hold my selectedItem. This "selectedItem" property would be injected into a presenter model through a setter function. In the setter function, the presenter would look at the selectedItem and decide which properties on the view class ( viewstack or states ) should be editable.
I have some misgivings about the value objects holding the type of editor they should use, that sounds like something that should be delegated to a UI/Presenter class.

ArrayCollection/Single XML Node problem

I've encountered a very frustrating situation that I would
LOVE some help with. I am getting xml back from an HTTPService that
I'm casting as an ArrayCollection. Very simple code:
[Bindable]
private var queueCol:ArrayCollection;
queueCol = event.result.Response.CallQueue.QueueItem;
This works great as long as there are multiple "QueueItem"
nodes. once the sml gets down to ONE QueueItem Flex throws an ugly
error. I have found this in other areas as well. It seems Flex
cannot reconcile xml of only single child nodes.
Has anyone else encountered this? Is there a
workaround/different approach to get around this?

You might try something like:
queueCol = new
ArrayCollection(event.result.Response.CallQueue.QueueItem is
Array?event.result.Response.CallQueue.QueueItem:[event.result.Response.CallQueue.QueueIte m]);
The SimpleXMLDecoder starts of converting a child node to a
property, but if there's already something there, it converts it to
an array. So flex doesn't have any problem reconciling xml with
single child node - it is making a best guess in the absence of an
xml schema. You can write your own decoder if you like (this is
what I have done), and hand it to the HTTPService to use in place
of the default. Then you can make it read a schema (if you have
one).

Problem filling DataGrid with XML - Object or ArrayCollection?

Hi,
I am trying to fill a datagrid with an XML file, rendered
from a PHP
script.
The problem is that - first time there is only one entry in
the XML
file, so when I receive the data using
event.result.root.child, I get
an Object. But second time, when there are two entries in the
XML
file, the return type becomes an ArrayCollection of "child"
type
objects.
This causes a problem when setting dataprovider of a
DataGrid....
So is there a way I can know what is the return type from the
XML
file, i.e., whether it is an Object or an ArrayCollection, so
that I
can set the dataprovider accordingly?

In E4x
If you have an xml structure like so:
<parent prop1='someValue' >
<child prop1='someValue' />
</parent>
to reference the parent use event.result
to get the child use: event.result.child; to get the child
attr: event.result.child.@prop1;

Eventhandler association with Arraycollection problem using DataGroup

I am using the DataGroup (similar to Repeater) and get the data from an XML file that fills an Arraycollection. The DataGroup requires an ItemRenderer that consists of labels and Image components surrounded by Canvas. The text, images x and y parameters from individual items from the XML file are all correctly accepted by the ItemRenderer. However, I have some mouse eventhandlers incorporated in the ItemRenderer but only the last item from the Arraycollection receives the eventhandlers. I want of course all items to receive mouse events.
So what am I doing wrong? I know all very well in Flash, which is my background but this type of problem not in Flash builder. Here is the code for the ItemRenderer:
<?xml version="1.0" encoding="utf-8"?>

You would need two columns(at least) in your load rule. The first column with the member name(s) of the base members you want to associate attributes to and in the second column the attribute member name.
If the dimension build properties for the first column you would set the dimension name and type of build level or generation(I suggest level) and set the level number. (Don't forget to set the dimension build properties to level build or you will get an error)
The second column, select the dimension then go down and select the attribute dimension that is associated to this base dimension
As an example for Sample basic you might have a row that looks like
100-10 Can
For the first column you would select Dimension = Product, Type Level value = 0
The second column would have Dimension = Product Type = Attribute dimension Pkg Type
In the dimension settings, make sure Product is set to level build and can associate attributes and allows association changes.

Problem updating a SOAP Web Service with ArrayCollection

Hello,
I am having issues POST'ing an ArrayCollection to a C# Web
Method. Here's how I have my application set up:
I have a DataGrid in my application and set the dataProvider
to be the result object of a Web Service operation. I set the
DataGrid's editable property to "true" and would like to be able to
edit the data and send off the DataGrid's dataProvider as the
parameter for the Web Method. If I edit the first row of the
DataGrid and trigger the operation, it gets saved just fine. If I
try to edit any other row this way, it keeps sending the same
packet (as verified by a packet sniffer) not allowing me to update
any other row. It seems the Web Service is sending the first 255
characters of the serialized ArrayCollection.
My questions are: why is this happening?
and
How can I fix this?
Here is the request of my Web Service operation:
<mx:request xmlns="">
<GlossaryTerms>
{GlossaryArrayCollection}
</GlossaryTerms>
</mx:request>
This is the definition of GlossaryArrayCollection:
[Bindable]
public var GlossaryArrayCollection:ArrayCollection = new
ArrayCollection();
Here is the SOAP packet that the C# Web Method is expecting:

New ListCollectionView(ArrayCollection) problem

Hey everyone,
I have a component that performs filtering on the dataprovider, but I don't want that dataprovider to be filtered elsewhere. The component I am using is an opensource auto complete textbox, which operates by text changing the dataprovider filter.
I want the data provider to be wrapped in a ListCollectionView so that the original dataprovider is never touched, but mimicked.
The problem though, is that the dataprovider always comes up empty this way... Any ideas?
<components:AutoComplete
                    id="individualName"
                    dataProvider="{new ListCollectionView(individualsPM.individualsCollection)}"
                    labelField="name"
                    prompt="Please select"
                    selectedItemStyleName="underline"
                    backspaceAction="remove"
                    change="individualName.selectedItem != null ?
                        individualsPM.getIndividual(individualName.selectedItem as Individual):
                        trace('nothing')"
                    searchChange="individualsPM.createIndividual(); individualsPM.selectedIndividual.name = individualName.searchText"/>

Try binding to a variable that is bound to that expression.

Arraycollection changing problem

hi,
i have the following variable defenition:
[Bindable] private var rangeData:ArrayCollection = new
ArrayCollection();
and i wish to silce it, and then update only the sliced data,
which i do like that:
var SyncRangeData:ArrayCollection = new ArrayCollection();
SyncRangeData.source = rangeData.source.slice( x1, x2 );
some changes to SyncRangeData
but, as i noticed, when changing the SyncRangeData, it also
changes the rangeData.
how can i copy from rangeData to another variable
[SyncRangeData], and then change it without affecting the original
variable [rangeData ].
thanks in advance!
micha

i just found out how to do this:
import flash.utils.ByteArray;
function clone(source:Object):*{
var myBA:ByteArray = new ByteArray();
myBA.writeObject(source);
myBA.position = 0;
return(myBA.readObject());

Problem with FTE in DataTips of PlotChart (missing texts)

Hi @all,
we have decided to use the Flex 4.1 and Flash text engine in our projects.
Now I have the following problem with the dataTips: the texts are appearing only partly if datatips of more than one point are showing. The behavior is not regularly.
Here is my code for testing (compiler options: hook at "Use Flash Text engine in MX components":

Has noone an idea?
The same problem exists with Legends. For this there was a help from Adobe with a style.
Isn't there a comparable solution for this malfunction?

Problem with checkbox item renderer in datagrid

I have a data grid having check box as an item renderer. I have viewed many posts in this forum but nothing useful in my case. I am failed to bind my datagrid itemrenderer checkbox with the field of dataprovider i.e. listUnitMovement.CHECK_PATH. Then I have to traverse data provider to check which checkboxes are checked.
[Bindable]
var listUnitMovement:XMLList=null;
In a function call
public function init(event:ResultEvent):void
    listUnitMovement=event.result.unitmovement;
     <mx:DataGrid id="dg_country"
                           dataProvider="{listUnitMovement}"
                              enabled="true">
                            <mx:columns>
                               <mx:DataGridColumn>
                                    <mx:itemRenderer>
                                        <mx:Component>
                                            <mx:CheckBox selectedField="CHECK_PATH" />
                                        </mx:Component>
                                    </mx:itemRenderer>
                                </mx:DataGridColumn>
                                <mx:DataGridColumn headerText="Latitude" dataField="NEW_LAT" visible="false"/>
                                <mx:DataGridColumn headerText="Longitude" dataField="NEW_LONG" visible="false"/>
                               <mx:DataGridColumn>
                                    <mx:itemRenderer>
                                        <mx:Component>
                                            <mx:Button label="Details"/>

                            </mx:columns>
                        </mx:DataGrid>

Hi,
Do you want to just check/uncheck the checkboxes based on the CHECK_PATH field.
Do you want something like this...
<?xml version="1.0" encoding="utf-8"?><mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Script>
<![CDATA[
import mx.collections.ArrayCollection;[
Bindable]
private var listUnitMovement:ArrayCollection = new ArrayCollection([{CHECK_PATH:true,NEW_LAT:109.233,NEW_LONG:232.22},{CHECK_PATH:true,NEW_LAT:109.233,NEW_LONG:232.22},{CHECK_PATH:false,NEW_LAT:133.233,NEW_LONG:702.22}]);]]>
</mx:Script>
<mx:DataGrid dataProvider="{listUnitMovement}">
<mx:columns>
<mx:DataGridColumn>
<mx:itemRenderer>
<mx:Component>
<mx:CheckBox selectedField="CHECK_PATH" change="data.CHECK_PATH=selected" />
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>
<mx:DataGridColumn dataField="NEW_LAT"/>
<mx:DataGridColumn dataField="NEW_LONG"/>
</mx:columns>
</mx:DataGrid>
</mx:Application>
Please let me know clearly what's your problem...Do you want to just bind the check box based on XmlList or something else..?
Thanks,
Bhasker Chari.S

Help needed in converting ArrayList to ArrayCollection

I am converting an ArrayList (Java) to ArrayCollection of Flex .
Please help me in this , i dont know whether this is correct approach or not
I have a Created a User VO ActionScript class on flex with two properties as uname , pass .
[Bindable]
        var result:ArrayCollection
private function displayDetails(event:ResultEvent):void
result = event.result as ArrayCollection;
<mx:DataGrid dataProvider="{result}">
                <mx:columns>
                    <mx:DataGridColumn headerText="UserName" dataField="uname"/>
                    <mx:DataGridColumn headerText="Password" dataField="pass"/>
                </mx:columns>
            </mx:DataGrid>
This is from my Java DAO File :
            ResultSet rs = stmt.executeQuery("select NAME , PASS from Users");
            list = new ArrayList();
            while (rs.next()) {
                User user = new User();
                user.setUname(rs.getString(1));
                user.setPass(rs.getString(2));
                list.add(user);
        return list;
With the below code ,the displayed DataGrid is empty with no data , please help me where i am doung wrong
Do i need to do anything more ?? The data is coming well on to the lcds server console .
Please help .

Hi Kiran,
Debugging solves most of the problems that you encounter ......you need to use a lot of debuggung so that you will come to know exactly what's
happening indeed...
So just put a break point at your displayDetails(event:ResultEvent):void function and try to watch the event variable and check the event.result
What is the datatype of the event.result ...Are you getting any data or is it null..???
Please make these observations and let me know...
Thanks,
Bhasker
