View 1 RepliesWhat is the role of source for an ArrayCollection or XMLListCollection? Is it used just once - when constructing a new ArrayCollection or XMLListCollection object and is it copied to some internal data structure of that object?
Because nothing is updated when the source Array (or XMLList) is being modified and the documentation confirms it too: The underlying XMLList for this collection. The XMLListCollection object does not represent any changes that you make directly to the source XMLList object. Always use the XMLListCollection methods to modify the collection.
This property can be used as the source for data binding. When this property is modified, it dispatches the listChanged event.
I'm asking because Flex examples related to dataProviders always use some Array or XMLList as source of data for a data-driven component. And I wonder, if using Array or XMLList is necessary at all - when for example loading data from external PHP-script.
I've following XMLList ,
<party/>
<party/>
<party/>
<party>A</party>

I would like eliminate blank node and to make an ArrayCollection like ( with count of individual party),
tArr = new ArrayCollection([ {Party:"A", Count:3},
{Party:"B", Count:2},
{Party:"C", Count:3},
[Code]....
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.
Is it possible to convert an XML string generated by a javascript return, into an ArrayCollection? I have looked into SimpleXMLEncoder as a possible solution, but that seems to deal more with a file than a string. My XML tree is pretty detailed so I need something to handle multilayer XML nodes.

View 5 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" >
<mx:Script>

When the XMLListCollection is updated in the DataGrid, I want it to add the XML (bind it) into the Model. How would I do this? Or if not possible, how would I manually add XML into the Model?
This is a rough example of what I'm trying to do. Adding data to the DataGrid works fine; it just doesn't go into the Model when sending to the HTTPService.
<mx:Model id="model">
<root><colors>{collection}</colors></root>
</mx:Model>
<mx:XMLListCollection id="collection" />

I am trying to display content of xmllistcollection in different fields in my datagrid however unless I use an itemrenderer the value is not displaying in the grid. The xmllistcollection is populated from a webservice call. Inside my item renderer i use a custom namesspace to retrieve contents from the xmllistcollection
value.ns::firstName
However if I try something like
dataField = "ns::firstName"
In the datagrid without using an item renderer I get no data output.

I've written the following custom component, SubNavBar.mxml:
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" height="100" width="300"
creationComplete="init()">
<mx:Script>
[Code]...
Whenever the trace function runs in init(), the property menuItems returns null. I don't seem to have this problem with other variable types, like Boolean or String. Is this due to the size of the XMLListCollection object? How can I set up this SubNavBar custom component with XMLListCollection property and bind it to a control in the component?
(I'm using Cairngorm)I have a combobox that displays items form an XMLListCollection that's in my model.I want to only view the items (XML) whose "sent" properties is false.. like item.sent == 'false'.This filter must apply only to this specific combobox, not everything that's bound to the XMLListCollection source.And of course it must update and refresh the filter if the source changes..I'm trying to use filterFunction but don't understand how it works...

I'm trying to loop through an XMLList and rather than giving me each item in the list as XML, it's just coming back with the positions as strings e.g.
[Code]...
It just alerts "0" or "1". If I inspect the 'item' variable, I see the same thing. But if I inspect 'myList' it looks like the XML. I've also tried myList.children() and strongly typing 'items' to 'XML' but nothing I do has worked.
If I have an XMLList object in Flex, what is the proper way to check to see if the list is empty? Should I just compare the result of myList.length() > 0, myList.toString() != "" or try another method altogether?
