I've developed a component which is a combination of a few items (canvas, labels, etc...) but when I try to bind it to a variable such as: {stationXML.getItemAt(1).AAA.@value}, it doesnt work. Before I combined all the items in a component, they were all in the main MXML file at which time they worked. Not sure if it matters, but the "stationXML" arraycollection variable is declared inside the file "Station.as".
View 2 RepliesI have an AS3 function that runs when a URLRequest fails. I need to be able to use this function to assign global variables that I can then check against using other functions. How do I assign global variables inside of a function?
Edit:This is the variable (soundFile2Exist) I am trying to get outside of my function:
function onIOError(e:IOErrorEvent):void
{
var soundFile2exist = null;[code]...............
I've been trying to get these variables that are defined inside this XML Array, outside of the XML array using _global, so that i can use them else where in the animation, but i'm not getting any purchase.

Is is possible to bind class properties to mxml components ? E.g.: I have a class A.as with a String property nameValue. What I want to achieve is always having the latest value of a mx:Text component in nameValue.

Does there exist a Flex view component that you could just pass it a custom object with all public fields/properties that it could reflect over and produce a basic UI view using flex components. Is it possible to use something like the Spark DataGrid with one item laid out vertically. It would only have to support:

In flex, how to get global coordinate position of a component?
View 1 RepliesIs it possible to make global functions, much in the same way you make a global variable, reachable from anywhere in the project?
View 1 RepliesI am trying to determine the global coordinates of the visible rectangle that is currently rendered on the stage.
Specifically, if a canvas has an explicit height and width and is a child of a panel that has a scrollbar, the scrollbar can "hide" a part of the canvas. ContentToGlobal(x,y) provides the global position of the content at the time, but content coordinates can scroll off the boundaries of the parent panel and continue to give x,y coordinates that are not visible.
Is there a way to determine the viewable rectangle that is not hidden by anything?
I want to constrain the height of a flex component to the height of the browser viewport.
The component's children are populated from a database table using a repeater, and are basic checkboxes. There are enough of them that the flex app ends up being about twice the height of the screen, which means some of the rest of the layout goes crappy on me. How can I force the component that contains these to limit itself to the size of the viewport?
The variable currentIndex is declared globally and initialized with a certain value say '0'. How do I hold the value of currentIndex which is incremented every time the function is called? In the given code, every time the function is called, the value is reinitialized.

I'm trying to make a global eventListener. Everything works fine, the KeyboardEvent.KEY_DOWN fires all the time .. except the cases when the textInput has a focus.Here's how I attach listener:

I have two components. One is called "InsideComp" and one is called "OutsideComp". OutsideComp has InsideComp as one piece of its component, and in my main MXML file, I have embedded an instance of OutsideComp. How do I access a public variable of InsideComp within my main MXML file?In Actionscript, I could just do something like:OutsideComp.InsideComp.valToChange = 5; But I dont know how to do it in MXML. I know this is probably an easy question.

I have a class DataModel which has been made bindable
Within Mainn.mxml I have two components: DataGrid (used for testing) & CustomComponent (which extends Canvas)

I have a custom component based on mx:ComboBox. Within it I connect to an HTTPService (the url is passed as a paramter) and bind the combobox. Parameters to be sent to the HTTPService are passed to the component. This is working fine. But I want to modify it to make it re-usable with other HTTP service URLs, which return the XML in a different format.
My challenge is how can I bind a custom component to a node dynamically at runtime?[code]...

I am loading a component which makes a HTTPService call to get data that will then be used to set certain variables in the component. I make the HTTPService call in an init() function (for the initialization event) and then set the variables according to the data received in the HTTPService result handler. However, the variables are still null at both the initialize stage and at the creationComplete stage. If I try and read the variables in a creationComp() function (for the creationComplete event), those variables are still null. Is this correct?
I guess I don't understand the flex initialization cycle very well. When are those variables actually set and available to be used? I need to manipulate those variables automatically after the component loads. Is there an event that comes after creationComplete that is appropriate or some other way to approach this? I am using Flex 3.
I am creating a custom component in Flex with extends the BorderContainer class, and I would like to be able to place additional content within the tagset when I use it in my main application, like this:
<components:CustomComponent title="Hello">
<s:Label text="If you have one enter it below:"/>
<mx:Spacer height="15" />
[Code]....
This works just fine, except that my component definition had some additional things inside of it, such as a <s:Label/> and styling, which is replaced by the content within the tagset above when I go to use it.
If I do not put anything within the tagset, the content that was originally in the component is not replaced.
Is there a way that I can simply append additional content inside of the component when I go to use it, instead of it being replaced each time?
How do I say an MXML component is inside some package? Well, it's in a different folder... I know how to do it ActionScript... But when I do in MXML I don't declare the package explicitly because I don't know how, and when I call it to my application, it states that The prefix "package" for element "package:Component" is not bound.
View 2 RepliesI'm using Flex with Cairngorm framework.I have a custom component which I create like this:
<components:FriendSearchPaginator id="searchResultsPaginator"
paginationElement="{_model.findFriendsPaginationElement}"
visible="{_model.friendsSearchResultsPaginatorVisible}" />
Where the findFriendsPaginationElement is inside the model locator:
public var
[Bindable]
findFriendsPaginationElement:PaginationElement = new PaginationElement();
Inside the custom component I have button that uses a property of findFriendsPaginationElement object:
<s:Button id="previousButton"
label=" prev "
click="paginateSearchResults(false)"
enabled="{_model.findFriendsPaginationElement.more_previous}"/>
But I get a warning from Flex that the binding wouldn't work that way and it doesn't. It works the first time I load up the component but every time I change findFriendsPaginationElement it doesn't reflect on the component. Do you know how I can go about doing this? (making changing a value in the binding variable changes the status of an element inside a component?)

View 1 RepliesI googled for almost a day to find the answer to my question: [URL]. This almost works (and is a great solution), but the solution doesn't work when I do:
1). Copy and paste multiple-line texts.
2). Write long and scroll the texts.
I also found another working example at: [URL]. (The autocomplete prompt appears when you press ctrl+space right at the caret's position). But an email from its author says he uses monotype fonts to calculate individual character's location. Is there a way to get multi-line input from a textfield?
