View 1 RepliesI'm trying to create some sort of rangking. For this, I'm using a multilevel xml which I create with a php file.

I'm a Flex noob and I've been struggling with this problem for a last week, and I'm at my wits end.
I have opened the following XML file
<root>
<person>
<city-of-death>asdf</city-of-death>
<place-of-death>qwert</place-of-death>
</person>

I would be so incredibly grateful if someone could help. I am pulling out my hair!
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.
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 have a requirement of sorting the <ename> in the XML with in the branch. The XML goes like this:
<company>
<branch>
<name>finance</name>

Is there anyway of type casting an ArrayCollection to xmllistcollection or to xmllist or can we covert ArrayCollection to xmllistcollection or to xmllist?
View 1 RepliesI'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...

View 1 RepliesI am having difficulty getting a reference to elements added after compile-time using the 'id' property. I have seen a few forum topics suggesting that this isn't possible, and that getting a reference to elements added this way is trickier, but never just exactly what that trick is. This code throws a fun little: Error: uncaught exception: Error calling method on NPObject! [plugin exception: "ReferenceError: Error #1069: Property canvas_tentpoles_0 not found on SGraph and there is no default value."].

I have an XMLListCollection object that contains items with an ID property. I want to find one particular item by id and then get it's index in the collection. This is done to be able to tell the comboBox (whose dataProvider is the XMLListCollection) the index of the item to display.

View 1 Repliesdoes anyone know how to shift all the array elements by one or more without deleting the array itself?
Something like rotating the array:
1,2,3,4,5,6,7,8,9,10
10,1,2,3,4,5,6,7,8,9
9,10,1,2,3,4,5,6,7,8
8,9,10,1,2,3,4,5,6,7
7,8,9,10,1,2,3,4,5,6
When i create a menu, the dropdowns go behind the flash element. But in some sites, like Digg, it is shown above. z-index is of no use
View 2 RepliesIs there a way to access the DOM-Elements of a mxml file in a way that you can in JS (e.g. using Prototype or jQuery)?
I need to know if a top-level element has a child (sub-sub-...-childs) with a certain id.
In JS (using prototype) it would be something like:
$('tabs').select('[id="something"]');
Is there any tool available for Flex applications that acts similar to Web Developer or Firebug toolbar to inspect UI elements? Basically in a complex hierarchy of UI controls allowing you to browse the elements and see properties such as x and y coordinates, width, height, id.I'm interested in tools that would allow you to do this at runtime, since most of the properties are dynamic.
View 3 RepliesIn a Flex webapp, is there an easy way to go about applying a sort to the children of an XML element, based on the children's attributes? Example follows below:
XMLListCollection:
<a anotherProp="ABCDE">
<e prop="AB">1</element>
<e prop="BC">2</element>
</a><a anotherProp="FGEH">
<e prop="HF">3</element>
<e prop="AD">4</element>
<e prop="AC">5</element></a>
I would like to sort the <e> elements, within each <a> element separately, according to their "prop" attribute. My code for generating the array containing the <a> elements is along the lines of:
for each(var node:XML in initialInput:XMLListCollection){
if(node.localName()=="a"){
//I was hoping to be able to sort the <e> children of the node variable here
xmlListCollectionVar.addItem(node);
}}
At the end I would like the <a>'s to remain in their defined order, but their <e> children to be sorted based on the "prop" attribute. So far if I try:
node.children().sort=someSortVar
Where someSortVar has its fields set to:
SortFields("e.@prop",...)
I get an exception about a null value. Any way to convert the children list to XMLListCollection, sort it and integrate it back into the node variable?
I'm writing an application in Flex / ActionScript and have a number of class member variables of type Array storing data. My question is: what's the "best" way to clear out an Array object? I noticed the ArrayCollection class has a function removeAll() which does this, but the basic Array class does not. Some possibilities I've considered are:
Iterating through the array, calling pop or shift on each element
Setting the array length to 0
Setting the member variable to a "new Array()" or "[]"
Anyone know how to animate the size/position of child elements of a layout in Flex 4 ?
I have a list component with a custom layout. I want when I change the positions of the child elements I want them to animate their move to the new positions.
Does anyone know if its possible to access children elements in a SWC? I have created some MC's and inside of some of these MC's I have some dynamic textFields. I export the content to a SWC and load it into my Flex project. No problem loading it or accessing the parent elements, they display fine. But I want to access the textfields nestes in the MC's and modify the text. When I debug the app, I can see the textfields as child elements. It's typed as a TextField and the Instance Name is the same as input in the Flash IDE but I cannot access it. When Flex compiles it throws an error saying it doesn't recognize the method. I've tried to insert actionscript on the timeline, linked external classes and nothing can be accessed.
View 3 RepliesI need to animate a lable movement between 2 canvases...The mxml example of the code is:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" applicationComplete="main()" frameRate="1">
<mx:Script>[code].....
Currently the problem is that the label actually do not leave borders of the first canvas (I see scrollbars instead of it).I think this is related to globalToLocal conversion problems, but do not understand how to use it.Also another question is how to animate the movement corretly, because move function performs movement without any visible action.
I have an ArrayCollection as mentioned below.
private var initDG:ArrayCollection = new ArrayCollection([
{fact: "Order #2314", appName: "AA"},
{fact: "Order #2315", appName: "BB"}[code].....
I want to populate a ComboBox with UNIQUE VALUES of "appName" field from the ArrayCollection initDG.
<mx:ComboBox id="appCombo" dataProvider="{initDG}" labelField="appName"/>
One method I could think is to loop through the Array objects and for each object check and push unique appName entries into another Array. Is there any better solution available?
