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 have a object that is extended from arraycollection. This object has to access and manipulate the arraycollections source object. When this happens, the local sorted/filter copy of data goes out of sync with the source data. To line things up correctly, the sort/filter needs to be re-applied.
To do this normally, you would call refresh() on the arraycollection, but this also broadcasts a refresh event. What I want is to update the sort/filter without dispatching an event.Having looked into the ArrayCollection class, I can see it is extended from ListCollectionView. The refresh function
public function refresh():Boolean
{
return internalRefresh(true);
}
is in ListCollectionView and it calls this function
private function internalRefresh(dispatch:Boolean):Boolean
{
if (sort || filterFunction != null)
{
[code]....
annoyingly, that function is private and so is unavailable to and class that extends ListCollectionView. Also, a lot of what is in the internalRefresh function is private too.Does anyone know of a way to call internalRefresh from a class that extends ArrayCollection? Or a way of stopping the refresh event from being dispatched when refresh is called?
I am doing this simple project using Flex 4 SDK and I got stuck with this simple problem: I have turned sortable property for AdvancedDataGridColumn to false, but the column header is still rendered as:
As You can see, my label for this header is "06", but the column header is divided and it keeps the place for sort arrow.
How can I change this? I would like my column header to contain only my label.
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 am using Adobe Flash Builder 4 Premium. I have a mx:DataGrid and a s:TextInput, and I am trying to set up a search box that filters the DataGrid on each key press.his page shows a nearly perfect example of what I'm trying to do, except that I'm setting this up in a s:TitleWindow, which is brought up as a popup using the PopUpManager. The list I'm trying to filter can be very large. It is a list of usernames, fetched from a MySQL database via PHP. Since it can be so large, I want the list to be populated once in the main application and then referenced in the popup window so that it doesn't have to fetch all the usernames each time the user opens the popup.I have all of this working fine for the first time you bring up the popup, but if you close it and bring it up again, I get this runtime error:I also get this error if I attempt to set the filterFunction back to null just before closing the popup.See sample code below:
Main Application:

How do I sort this time ArrayCollection? I need it to be sorted from earliest to latest.
View 2 RepliesI'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" >

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?
When I get a collection back from the service tier, I create an ArrayCollection and apply a sort. When I add an item to the collection later on, the sort is still in place? It seems to be the case. I thought I was only sorting it once, not applying a sort that will stick??Here is the method for adding an item:
private function onAddNewClick():void
{
var fileTemplate:FileTemplateDetailDTO = new FileTemplateDetailDTO();

Normally, I'd just like to sort the array alphabetically using the name field, which is easy enough using the following code. However, I'd like to create a radio button called 'loadedRadioButton' and when it's click on, I'd like to sort the array on the loaded value first(any items with loaded=true should be at the top, sorted alphabetically), then afterwards, any other items with loaded=false, sorted alphabetically should follow afterwards, how can I do it?

View 1 RepliesI 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.
Here are the strings this array can contain (in the correct order):
'recipients,' 'columnSelector,' 'headerImageLink,' 'title,' 'mainText,' 'text,' 'bodyImage'
Now, to sort them, I obviously don't want to do something like this:
if( a == 'columnSelector' && b == 'headerImageLink' ) return -1;
else if( a == 'columnSelector' && b == 'title' ) return -1;
else if( a == 'columnSelector' && b == 'mainText' ) return -1;
So that brings up an interesting thing. I know you can optimize the above some using something like this:
if( a == 'columnSelector' || a == 'bodyImage' ) return -1;
This would get the last two, but lately I have just wanted community input on issues I have had in the past. So the question is, what is the best way to write a custom sort, using a relatively random order (not alphabetical, etc)?
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.

I read a lot of the explainations like:

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>();

sortL.fields = [new SortField("startDate", true)];

<startDate>2/15/2011</startDate> as per my understanding it is sorting until 0-9 numeric fields only. Is there anything I need to add in this code for numeric sorting?
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,
