In my main application I have a viewstack with 3 child views. In the viewstack change handler, I programmatically change the selectedchild property.
I understand that the initialize method for the view is not called every time I change the selectedChild Property. So I tried to invoke the init method programmatically too..

I would like to send variables or parameters from Component to Main (MXML) Application. Like my component is FileUpload.mxml and would like to forward the uploaded file details from FileUpload.mxml to Main.mxml.
I tried the following procedure :

to get the reference for the FileUpload component, however, I am unable to get the variables from the FileUpload.mxml file.

View 2 RepliesHow can I add an MXML component as a child of the main application using ActionScript. It's not possible to instatiate it, is it? Assuming that behind every mxml file stands an actionscrpt3 class, I tried to import it but id didn't show up.
View 1 RepliesI have an event, which I have dispatched in my main.mxml:
var evt:UserEvent = new UserEvent(UserEvent.USERINFORMATION);
evt.userVO = storeObject;
this.dispatchEvent(evt);
I can listen for it while in my navigation.mxml file, by using
this.parentApplication.addEventListener(UserEvent.USERINFORMATION, onInfo);
But in other component, I can not listen for it, even trying the same as I did in navigation.mxml.
tracing it back gives me an undefined.
the second component is in a viewstack in navigation.

I've been trying to create a custom mxml component that extends another custom mxml component (i.e.MyMXMLComponent -> BaseMXMLComponent -> Group). I've been reading that trying to add visual children to MyMXMLComponent caused error with Flex 3 but that's no longer the case with Flex 4.
What I want to know is whether this is a supported/fixed/documented feature of Flex 4? or just some undefined behavior in Flex 4 that may get changed with future updates?
if this is supported and documented feature, does anyone have link pointing to adobe document stating it as such?

So I'm using a custom auto suggest component that I found online at [url]... The background color for the item is set within the following folder[code]...

I am trying to create my first real world Flex application. I will have a lot of different data entry / data view screens so I thought I would create many different components to deal with each different type of data that was being returned. I have a MXML application called Layout, and have component called "Navigator" which controls the menu, as well as a ViewStack called "MainContent".
I want the Navigator component to change the ViewStack on the Layout application to that of another Component (each Component is embedded within the Canvas of each ViewStack). I have a click handler on my Navigator which looks like this: Layout.ContentFrame.selectedChild=event.itemRenderer.data.clickValue; However it shows the error "Access of possibly undefined property ContentFrame through a reference with a static type Class." Is my approach a good way of doing it? I have attempted referencing it using FlexGlobals.Layout and topLevelApplication.Layout... neither of which work?[URL]

I have a checkbox in a component:
<s:CheckBox id="myCB_1" />
In my main.mxml I need to test for the state of the checkbox. I originally had all my code in main.mxml, but it was getting really long, and I thought that it was better practice to break my code into components. Also, I have other projects where the same concept will apply.I have the following function :
private function checkAlarms(currentTime:Date):void
{
if (!breakfastAlarmSounded)[code]....
doesn't work. Someone mentioned that I need to create a variable in my component that refers to the id (myCB_1) of checkbox, but I don't really understand or know how to do that, and they didn't elaborate.How do I test for the status of the CheckBox "myCB_1" in the component from within my main.mxml?

I need to be able to call a method from a component located under the main application in Flex 4. Can anyone tell me please how to do this without using FlexGlobals please?[code]
View 3 RepliesI've always just developed my projects in as3 instead of mxml and I usually just setup my application to run a main actionscript file as my main doc root, sort of like how you do it in flash but in flash builder I do something like this:[code] how can I call place a call to that function hitme() within the call_from_outside() function between the <fx:Script> tags?The reason why I'm doing this is because I have some flash swfs that I load into another swf file and I can access the top level public functions of those flash swfs, however the top level of the flash builder/flex swfs is the main mxml file not my fake as3 class root. Of course I should think there is a way for me to access the as3 class methods of the mxml component but for keeping things with the same structure, I can bypass having to modify my loader scripts.
View 1 RepliesI hope I have worded the question ok. I know that you can pass the 'id' of the component but I'm just wondering if there is a more generic way. I have tried using 'this' (shown in example below) but the 'this' keyword refers to the application.

There's an HTML technique known as innerHTML that allows Javascript to add/delete/edit HTML elements. Can actionscript do something similar to MXML?
For example, my main application's mxml part is:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Button x="29" y="347" label="Button"/>
</mx:Application>
But after running an actionscript code, I want the user to see the result of:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Button x="29" y="347" label="Button"/>
<mx:RichTextEditor x="183" y="24" title="Title">
</mx:RichTextEditor>
</mx:Application>
Is this possible with Actionscript inside a MXML file? p.s: is this possible with Degrafa library elements?

this swf is loaded into another swf using Loader and added with addChild(loader).i then need to call the init function from the parent swf. how can i do this? just calling

If I need to call a specific function in the parent application from a child in a flex project, what's the best practice for this? Would it be to dispatch a custom event from the child and have a listener call that function? Or to directly call the function with FlexGlobals.topLevelApplication?
