When I try to access the hidden TABs of my tab navigator control in action script, it returns a null error. But it works OK if I just activate the control in the user interface once. Obviously the control is not created until I use it. How do I make all the tabs automatically created by default ?

In my Flex application, using a custom control, I am making a JSON request to grab some data from the server. My rendering depends on this data such as knowing how many boxes to draw. How can I either force the rendering to wait until I've got the data before drawing to screen or have the boxes draw once we receive the data? I have an event listener for Event.COMPLETE for my JSON request and in there, I call methods that add to the control. I've tried invalidateDisplayList but that doesn't seem to do anything for me?
View 1 RepliesI find it kind of weird that IE8 would render my as3 different than firefox, and that I can't trust the movie player. I'm creating my movie object code using jquery and javascript. When I play the movie in the modal display the first time, it play and renders correctly. On the second time, the play controls dissappear.
I have spend about a 2 days on this, and have isolated it down to this object. It looks like the stage.stagewidth is inconsistent after the 1st time the object loads on a clients browser. Once the file gets cached by IE8 in the temp folder, it seems to change.
So I have replaced the stage.stagewidth with a var that is pased via flash vars, fv_Player_Width, which is 640.

We have this wicked project requirement to force play a flash video from start to finish upon user login. One possible solution is to autoplay the video and disable the mouse and keyboard while the video is playing. Is there a way to disable the mouse and keyboard in flash? This means you cannot click anything and type anything until the video finishes.
View 1 RepliesI am using a single FLV file. On the player interface in addition to play/pause and stop, I have a number of chapter buttons, which I have successfully pointed to the corresponding points in the FLV file. I need to find a way to capture and hold the relevant start and stop times of each of these chapters so that when I am in each chapter, the stop and play buttons will reference the chapter times and control only the relevant chapter, ie in Chapter Two clicking stop will reset to beginning of Chapter 2, not the start of FLV file. Not sure if there are built-in properties and methods I can use, or I need to create something custom.

View 1 RepliesMy Flex chart has code that creates a legend from each data series. Currently, I have the drawLegend function execute when a button is clicked.
I am trying to get the legend to draw automatically but I am having trouble determining when to call the drawLegend function. Users click on an 'Update' button which retrieves data. I want the legend to get created after this, without the users having to click on another button.
I have put my drawLegend function in several places (ResultHandler, afterEffectEnd(for chart animation, etc.) and nothing works.
Sometime after the series has been added to the chart and after the series animation ends, the legend can be added.
How can I trap this point in time and call my function?
Below is the code I used to create the legend. Note that even though the code processes each series, I noticed that the Fill color is null if it is called too early.
private function drawLegend(event:Event):void {
clearLegend();
// Use a counter for the series.

I know this question was asked before, but none of the solutions work properly. How do I render a basic html in flex 4 without an iframe? I saw textarea renders some weird format that would suffice if it would work. For example I wan't to add an image like this

then 1. I press enter 2. I add the image again like above, I get the img tag inserted 10 times or so; which is weird (but not funny at all). All things being equal, html is a much normal approach, is there a basic renderer for flex 4 that works ok?

Coming from a pure programming background where I have a render() and which image is drawn over which, is based on in the order of the drawn function of the image being called.
But after trying out Flex, I notice that Flex allows images to be created & drawn in the MXML file using the <image> tag and that I can also create and draw images in a AS class file link to that MXML file.
But it seems like any images created in the MXML file are drawn over the images created and drawn in my AS class file.
Is there a way to specify the draw order of the images?
I have a custom ActionScript component that I'm using in a Flex application (Flex 3.3, ActionScript 3). This component contains an Image control whose visibility is set dynamically based on a property of the data element provided to the component. The problem is that even when I set the image to be visible, it will not render onscreen. Is there something specific I need to do in order for the image to render? Snippets of relevant code below:
override public function set data( value:Object ):void {
_data = value;
if( _data ) {
if( _myImg ) {
_myImg.source = someImageClass;

[URL]. Our client communicates with a Rails backend to get login details and then logs into an Adobe LCCS server. We have been cruising right along but around noon yesterday we developed a bug that causes the swf to not render until you refresh the page. On subsequent refreshes it pops up right away. The problem happened even when I disabled the code that checks in with the Rails server. How could refreshing make a difference?

View 1 RepliesI am currently developing a dynamic LineChart in FLEX 4.I am implementing a Tree control next to my LineChart, which will filter the LineChart dataprovider and lineseries. The tree control has several branches and ultimately 5 children (leaf nodes) at the bottom of the last branch.I need the leaf node/children to be displayed as checkboxes inside the tree control.As I understand,this will require overrides in the TreeItemRenderer class.This is where I am a little confused on how to implement that.Currently I can distinguish between leaf and branches using this code, in my main MXML component.I added this because it may be helpful to some beginning FLEXdevelopers, such as myself, who cannot easily find this functionality documented well:
private function treeClick(e:ListEvent):void {
_selectedItem = Tree(e.currentTarget).selectedItem;
if(mainTree.dataDescriptor.isBranch(_selectedItem)) {[code].....
I am looking at the TreeItemRenderer override class from the following example here: In the example, they override the "createChildden" super function to add checkboxes to the tree control.My question is, can I override the createChildren function directly in my MXML component, and not have to use an entire class file to override this functionality? Must I re-invent the wheel to do this?Also, how can I distinguish that my treeItem is a leaf node and not a parent, in the override function? I only want to add checkboxes to the leaf nodes, how can I differentiate? The following example adds checkboxes to all branches and leaf nodes, but I want to add checkboxes only to leaf node/children. How would you approach that?
override protected function createChildren( ): void
{
super.createChildren( );[code]............
Here is my tree tag:

What is the best way to render to a UIComponent which hasn't been added to the stage? (I'm using UIComponents as renderers for objects, and want to render new copies for image export, filtering, etc.) Two strategies I've seen/used so far include realizing the component to ensure it calls all the lifecycle methods: Add the component to Application.application, render with BitmapData.draw(), remove component. This is similar to what I've seen done for printing unrealized components as well. Add the component to a pop up window, render with BitmapData.draw(), dismiss popup after rendering complete. I believe both of these just rely on the UI not refreshing while the current thread/event is executing, though (1) could also rely on the component being realized out of view.

View 1 Repliesi got an Arraycollection which holds other arrays in it.i want to display the data inside with an item render but cant manage to do this
here is example code to explain my question
<s:DataGroup dataProvider="{news}"

and this is the item render
<s:Label text="{data.??/}"/>
now what i dont understand is what comes after data? in the array collection the data goes like this : myArrayCollection->[0]->firstname
so when im binding data to item render,how do i represent the [x] to get to the specific name that i want? this obviusly wont work
<s:Label text="{data.[0].name/}"/>

View 1 RepliesI am trying to get anytihng from my SQLite to render in Flex, and I can't figure out how to display any data, even text, in Flex. What am I doing wrong?
[Code]...
I've tried a number of different components, and I can't seem to get the data to bind properly (although this code finally doesn't have the dreaded "Data binding will not be able to detect assignments to... " message, or the other dreaded "Property undefined" message).
So updateDisplayList is for laying out, positioning and sizing a component's children. It seems a waste to me, however, to have all that code running every time a render is called, even if no changes have been made to the relevant properties or child properties.The way I get around this for performance's sake (working on mobile) is to set a flag inside of my overridden updateDisplayList that lets a big part of my own sizing/positioning code run only the first time.Is this a bad idea/ big mistake? I just can't see the benefit to letting it run every time otherwise if I don't expect anything that affects sizing/positioning to change.

View 1 RepliesI have an app w/ a login screen. When the user hits "enter", the state changes to "login" & a child component is triggered to load (though the child stays invisible at the moment). The child contains many functions that the user needs upon logging in (ie their screenname & settings are retrieved from a database). The following is included in 'Parent':
<local:comp id="localComp" includeIn="login" includeInLayout="false" visible="false"/>
<mx:Button label="login" click="currentState='login'"/>
<mx:Button label="logout" click="currentState='Default'"/>
My problem is when a user logs out (state changes to 'Default') & then logs back in (state changes back to 'login') the child doesn't get "triggered" again & the functions w/in the child don't reload. Is there a way to force my child to refresh?
Note: While it would be easier to just move the child's functions to the parent it is complex...I moved these functions to the child to make it easier to follow
UPDATE: I even tried adding an "exitState" to my state:
<s:State name="login" exitState="removeElement(localComp)" />
This doesn't work either, as I get an error: "RangeError: Index 0 is out of range."
UPDATE: Even though you are allowed to call a child's function from a parent, my problem is that the child needs to be "created" in order to not show errors. It makes no sense to me why the flex team would make something like removing & adding children so complicated.
