Flex :: Source In ArrayCollection And XMLListCollection?

Aug 29, 2011

What 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.

Flex :: Converting Nested ArrayCollection Elements To Another Class?

Feb 1, 2011

I have an ArrayCollection and each element is an instance of the TreeNode class (a custom class made by me) that has a "children" property which is an ArrayCollection of more TreeNode elements. That way, I have a tree of elements in an ArrayCollection structure:

tree = new ArrayCollection([
[new TreeNode(param1, param2, new ArrayCollection([
[new TreeNode(param1, param2, null)],

[Code]....

But my problem is: I need to have the same "tree" structure (it doens't need to be the same variable) filled with instances of another class. How can I achieve that?

Flex :: Mxml - Components Bound To Empty ArrayCollection At Load Time Don't Render As Expected When The ArrayCollection Is Updated?

Oct 27, 2009

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>

Flex :: Bind XMLListCollection Into Model?

Mar 24, 2012

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" />

Flex - XMLListCollection Properties In Custom Components Always Null?

Dec 11, 2009

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?

Xml :: Select Items From XmlList?

Apr 7, 2010

My Flash designer is reading an XML stream I'm sending back to the browser (I'm a C# dev). We have this working fine.

He is then selecting into an XMLList where a element has its id a certain value i.e. . This is also working just fine.

In this XmlList, are Events, that look a little something like this:

event
startdate
enddate
end event

I don't know how to use the formatting here - but each of those items is an element. startdate would have a value such as 04/02/2010 and enddate 6/30/2010.

Now, from this XmlList I do have of Events, I need to select all Events where a new variable myDate, falls in between the startdate and enddate.
