Shouldn't I be able to read loaderInfo inside the creationComplete handler? I'm trying to pass a string from the html to my flash component, that's why I have to get loaderInfo working.
I have a problem with Flex module. I want to access url variables by this.loaderInfo.url, i call a function in createionComplete handler of module and sometimes it works and sometimes it doesn't. (Can't access... null). Any suggestions?
This function is called in creationComplete handler of module. And although it throws error window, the alert with url shows and contains url of module.
private function checkModuleUrl():void
{
var url:String = this.loaderInfo.url;
Alert.show(url);
}
I have preloader code in my main FLA, and I load the corresponding preloader (a small file) externally. When I detect that the file is fully loaded, I need to add the listener to the content that I want to "preload".[code]If I use it this way, the loaderInfo listener does not work, but if I add the listener ouside of the handler function, it does.The problem is, I need it to work from within the complete handler, because obviously, the preloaded can show the % completed only after it's loaded...
View 1 RepliesI am looking for a way to programmatically dissassoicate the click handler function from a button on my mxml component through actionscript code.
Something like what older actionscript let you do,
mybutton.click = null;

I have a class that loads a handful of external swfs, and a preloader class to handle them all as a single object.I was having some strange problems with the loading process and tried tracing the urls to see which file was bugging. For my surprise, almost all loaderInfo objects reported theirs url as null.With a bit of testing I came to the conclusion that they only report some url when the file is almost completely loaded. The docs say something about "possibly wrong urls" before progress events, but that would be in cases where redirect happen, and everything here is local with simulate download option. Also, "event.target.url" inside the very progress event handler reports null unless the target's loading is almost done. Unfortunately I don't have any piece of code with less than a hundred lines to show. But is there any undocumented behavior, known bug or common coding error that generates such situation?

How to I get the creationComplete function so that I can safely access swf objects? I thought going to the parent of all (the stage?) would work..I have tried unsuccesfullly to use :
stage.addEventListener(Event.COMPLETE, myCheckComplete);
but am having problems.
I have a Tree, which has an itemRenderer. On the itemRenderer, driven by the XML conditions, objects are created dynamically and added as a children to nodes. These new objects shall trigger an event handler ( some click events mostly ). How do I pass the event handler to the tree and later to the dynamically created new objects inside itemRendere?
Something like:
<mx:Tree x="534" y="49" newObjectsOnClick="newObjectsOnClickHandler">
I'm having trouble with updating a var and firing a function with it on creationcomplete.In the main component i declared a var artist. This var certainly works and has a value. I also need that var in another component: a profile component. I am able to get that var with:
newVar = Maincomp(this.parentApplication).artist;
I use the newVar in an API in the profile component. When i launch the API function with a mouseEvent, it works. However, i want to launch the API function on creationComplete and than the var doesn't work: it returns Null. I hoped that making all the involved vars bindable would help, but it doesn't. Extra code to make my case clearer:In main comp:
public function handleclick(cName:String):void
{
vName = "aVariableIGetFromAnAPI";[code]...
This code works, but point is that this code works if i call it with a MouseEvent, but doesn't when it needs to launch on creationcomplete. Or well, it returns Null instead of a value. I thought that making the involved vars bindable would fix it, but it doesn't.
I've created an button object in flash. The button contains 2 layers. One is the background image and on top of it is a textField. The textfield is dynamic. I use the button inside a movieclip and I export it in a SWC. The I'm trying to use it in flex.
I'm trying to do this:
var myComponent:MyComponent = new MyComponent();
myComponent.button01.theTextField.text = "Caption";
I get and instance of the button(myComponent.button01 is not null in Flex debugger), but the instance of the textField(myComponent.button01.theTextField) is null and I'm not able to change the text(but the default text appears onscreen). The code is compiled correctly in flex.
I exported the in swc the button control as well. So the button is not the default SimpleButton from Flash, but an derived class generated by flash(with the same name as the symbol defined in flash). It contains theTextField memeber, which is null.
Here is the button timeline(Layer 2 contains the textfield, and the textfield instance is named theTextField):
I have made a tile list is Adobe Flex as follows
[Code]...
the problem is the creationComplete event is not fired for each PageImageRenderer, and it is fired only for the tiles visible at start so the rectangles drawn in initComponents() is only drawn for those tiles with valid values, and when I scroll to next row using scrollToIndex() function the rectangles are shown with previous values. and no initComponents() is called for these tiles? however the data.name, data.class are correctly displayed but not the rectangles, why it is so? What is the proper event against which I should call initComponents()?
I am using the new Flex4 Spark stuff but I'm stuck at an awful problem. Let me explain a bit of the situation first. I have a container (mx:Canvas) in which I do addElement() of one type instances (DocumentWindow). The document window class is supposed to be the holder for a view according to the type of the document. The DocumentWindow class extends TitleWindow. I also have a task bar which is a mx:Canvas with buttonBar inside so that the windows should be switchable. So in 2 words I got windows holder and a taskbar. The strange thing comes now: When I put a DocumentWindow with type "doc" (which loads swf made by swftools) the window appears in the windows holder and as task on the taskbar.
But if first I open something else - DocumentWindow with type audio or video which causes the DocumentWindow to instantiate different view inside, the window doesn't appear on the screen neither a task button is being shown in the taskBar. I put a trace() on that and it shows that numElements is increasing, the taskBar ButtonBar.dataProvider.length is increased, so the things are there - just that they stay invisible until I open DocumentWindow with type 'doc'? I even tried to make DocumentWindow not to load the view inside because I thought that the only difference is the view... but then even the 'doc' typed DocumentWindow didn't show. A clue may be that creationComplete is never called until a 'doc' view is added.

I'm working with a large flex applications and I have noticed that one of our largest components (with lots of child canvases) takes about 6 seconds between the initialize and creationComplete events. I've been doing some reading and have found that having lots of nested canvases can cause slowdowns, but i'm not sure if this is where the slowdowns would be?
View 3 RepliesI didn't get the difference between those two event.What is the difference between them ?
View 3 RepliesI have a creationComplete="myMethod(event)" in my s:Application, and it runs fine on my 3 flex (Flash Builder 4) development machines. However it is not working on the 2 end user machines I tried it on today!
It is not executing the creationComplete at all, but it is running the application and it seems like all the other code is running fine - with the exception of possibly some other creationComplete code for other components in the app.
On my machines I have tested it under IE 8 and 9, FireFox and Chrome - on all 3 machines.
On these two machines it has the problem on both IE 7 and IE 8. I even installed FireFox new and it also has the issue. After installing the latest flash player and deleting all browser history/cookies it still has the problem.
What might cause the creationComplete to not execute?
Update: I tried using initialize() and no difference.
However, I believe I found the line of code causing the problem:
var isDebug:Boolean = new Error().getStackTrace().search(/:[0-9]+]$/m) > -1;
If I comment that out, it works fine. I need that to know if my app is running in development/debug mode or on an end users machine.
I have a simple component I created which I instantiate in my main program like so:[code]I receive the error "Cannot access a property or method of a null object reference" on the second line because newMessage was not fully created prior to hitting the second line of code trying to set my "body" textarea's text. I know I can build a "creationComplete" event handler, but isn't there a simpler way to do this?
View 2 RepliesI have a component that, once it's all ready, I need to set the state based on a variable I'm reading in from XML. I tried doing it with creationComplete, but it's apparently not ready, as the state isn't being set with elements rendering properly, but the states & rendering work fine if I do a subsequent state change with a click action on some element.
What should I do in this situation to make sure the state gets set at the right time & elements that should appear due to includeIn exist so they can be rendered? initialize instead of creationComplete doesn't seem to do the trick for the first time the component is created. Any successive calls to the component are fine.
I tried to send some services to fetch data in the creationComplete handler. Then I need to process the server raw data before displaying some sub components. Where should I put these kind of code?
View 2 RepliesI need to return to my original function after capturing an event (downloading something) with another function. The original function needs to return a value, which depends on the downloaded data. So, I'd like to pause original function for the time needed for the download and the eventhandler function to complete it's work, and resume it afterwards.
The obvious way is to set a flag value (both the original function and the eventhandler are within the same class) and make the original function check it until the eventhandler function changes the flag. But that would be wasteful, and my AS is slow enough already:) [other parts of the application utilise some heavy graphics]. Is there another way? Like an event that gets captured "in the middle" of the function? Or some other form of flow control?
In my flex application I use the viewstack.selectedchild() property to change the views.
When I revisit the views by the viewstack.selectedchild() property the initialize method doesnot get invoked..
I seem to be having a recurring problem attaching events to a button i have created within 2 other movieclips.I get the following error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
So it looks like it can't find the button, in order to attach the event listener. The question is why? I am attaching a similar event to a button on the main timeline and that works fine. So it looks like a scope issue, but I am referring to it properly.

Code:
import flash.net.navigateToURL;

Simple to understand problem, hoping for similarly easy solution:When I type in my search query, I sometimes get the "Error #1009 Cannot access a property or method of a null object reference" on the dataField = new ArrayCollection(result.data); line.

I have a spark DataGrid component with several columns and I want to have my application default to descending order on the first column in the DataGrid. I would like to use the built-in default sort that occurs when clicking the top header once. I have no need to sort the ArrayCollection I'm working with or change what the comparators are.I also want any user-generated sorting such as clicking on a different column's header to override the default sorting.
View 1 RepliesAny thoughts on a good way to accomplish something along the lines of
var request:URLRequest = new URLRequest("http://myurl.com");
var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE, function(event:Event):void {
System.setClipboard(loader.data);
});
It seems as if System.setClipboard() isn't available inside an event handler (which makes at least some sense given what I know about Flash security).get it to work? or block on the URL load so that I can then call setClipboard() in the main event flow?
how to delete and make and event handler "null". My question is: how to give that a movie clip its event handler back?

Is there a way to get the handler(s) function(s) of an event listener?
I'm trying to find a way to remove them without knowing what they are.
For example:
ActionScript Code:
if (mc.hasEventListener(MouseEvent.CLICK)){
// this object has a MouseEvent.CLICK listener
mc.removeEventListener(MouseEvent.CLICK, null );
}
Instead of null, I was hoping to find some function that retrieves the handler function.
