I have a flash element in a page that load a chart based on some complex queries that can take up to a minute to load. I call the query with this code :
var chartData:URLLoader = new URLLoader();
chartData.addEventListener(Event.COMPLETE, onLoaded);
chartData.addEventListener("httpStatus", onHttpStatus);

I have a Tree component that's used as a navigation menu between different 'pages'. When the user clicks a certain option in the menu, I switch the 'page' by switching between State components in my application. The thing is that when the user indeed clicks an option in the menu, I want to perform a validation of some of the information in a certain component. If the validation fails, I show an alert, and I'd like to prevent the navigation to the other page. One part of this is simply not changing the currentState of the document, but the tree component still goes on with the change event, and the result is page A still being shown on the screen, whereas the selected option in the tree is page B (to which the user wanted to navigate, but failed since some of the information wasn't valid).
I tried to figure out how I can cancel the change event on the tree component itself. The thoughts I had didn't quite fit nicely:
I searched for a slightly different event (such as 'changing' or 'startChange') on which I can call the stopPropagation() method (since the regular 'change' event is not cancelable), but none exists for the Tree component.
I also thought about always saving the current option that's selected in the Tree component by myself, and when the validation fails, I will set the Tree's selectedItem to that saved option. That's also ugly because such an action will raise another change event on the Tree, thus another change to the States components, and another population of the page in which I'm already at. That's something I really don't want to do.
I also though about using a different component, such as Menu (and I also found an implementation of a vertical Menu), but that doesn't even seem to help. The same problem will exist there.
There must be a best-practice for preventing a change process to commit!
I have a DataGrid, and what I would like to do, is when a user clicks on a row to select it, check a certain condition, and if it's met prevent the row from getting selected and keep the old selection intact.
View 1 RepliesIs there a timeout on the connection made by URLLoader.load? If there is, what's its value, where is it documented and can it be changed? Also, what event (if any) gets dispatched if the timeout occurs? Is there a difference between AIR and browser application in those regard?
View 2 RepliesRan into a weird Flex bug (i guess)... I am uploading using URurlLoader.load(urlRequest)... on cancel button click, urlLoader.close() is called.. but this doesnt abort the upload the file shows up on the server. Is this a Flex bug or am I missing something? Can anybody confirm if they have been able to abort an upload / load with the urlLoader.close() method call?

View 2 RepliesSo I have a contact form that works flawlessly in the Flash development area, but doesn't work in-browser. I've tried in multiple browsers, and it doesn't work in any of them. Here is the relevant AS3 code:
Code:
var url:String = "http://******/Scripts/sendContact.php";
var contactVar:URLVariables = new URLVariables();
contactVar.userName = commentName;

On a side note, if this helps any, sendToURL using the POST method doesn't seem to work with anything hosted on this server, but with GET it does.
I'm using hotkeys (ctrl + key) in my flex application. getting problem when my app is running in IE.when i press ctrl+D, im getting 'Add a Favorite' window of iE.How should i override the default behaviour of the browser.
View 1 RepliesIt rarely happened, I use a flash in exe type to access url in local server. It usually success to access the url. When it fail to access the url, open the ie to access the browser. the url works. After using browser, flash success to access the url. The url would return the JSON content. I use URLLoader to load url, and the return error is no responding when it happen.
If the error happen, it would not access the url even restart the computer.
I have a full screen flex application and I want the user to be able to scroll using browser scrollbars. I don't need mousewheel in the flex application and flex appears to block mousewheel events within itself. So mousewheel events do nothing.

Keeping into consideration the Actionscript 3 event HTTPStatusEvent:HTTP_RESPONSE_STATUS, which is ONLY AVAILABLE for AIR (and not Flash 9/10)
Quote from site:
Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0, Flash Lite 4
I would like to add the same EVENT by extending the HTTPStatusEvent Class of Actionscript 3 for Flash (9/10).
I'm working on Adobe Flash CS3 and I'm trying to get the "last" location of a URL loader (I'm calling a php with a header("Location: ..."); ) so I need the location after it changes. This should be made directly by flash and I cannot use php proxies not other.
Also, I cannot find the source code of the AIR HTTPStatusEvent Class, which I need to get the event (specifically, the responseHeaders and responseURL properties that the AIR class has).
I have code that sends variables to an .asp file to be put on a database, and all that works fine the database connects and is updated fine, the thing is flash doesn't recognize that the operation was successful and won't continue with the further functions. I understand this may be due to a problem on my asp file, but the SQL executes successfully which I see when i check my DB, so I was wondering if anyone could look at my AS code and see any problems?

I'm querying a web application in a remote server through XML files and receiving answers in the same file format. Until now, sometimes I received a connection error:
Error #2044: Unhandled ioError:. text=Error #2032: Stream Error. URL: http://server/Services/startSesion.com
at reg_jugadores_fla::MainTimeline/queryGQ()
at reg_jugadores_fla::MainTimeline/reg_jugadores_fla::frame1()
When this occurs, trying to access the services through a web browser, there's a test page where you can try queries, returns a "500 Internal server error". I managed that problem adding a listener to catch the error:
xmlSendLoad.addEventListener(IOErrorEvent.IO_ERROR , catchIOError);
But since yesterday I can't connect anymore using Flash while it's possible to access the test page. I'm not able to talk to any support guy as the company is closed for vacations! I added listeners to try to know what's happening and this is the result in the output window:
openHandler: [Event type="open" bubbles=false cancelable=false eventPhase=2]
progressHandler loaded:154 total: 154
httpStatusHandler: [HTTPStatusEvent type="httpStatus" bubbles=false cancelable=false eventPhase=2 status=200]
AFAIK, status=200 means OK but why the COMPLETE event isn't dispatched?. So, is there anything I can do or just wait until the tech guys return from the beach?

I hate that you can't just say e.target.src or whatever - is there a good way to associate URLLoaders with the URL they loaded data from?
I've done a lot of C# programming with both Winforms and WPF. I'm working on a Flex/Air app now for cross platform support. But this is my first flex project, so I'm learning as I go. I've got a window that I want to popup, that the user will fill out a form, then hit OK or CANCEL. I set it up the same way I would've in C#, but it doesn't work, and I can't really see a way to make it do what I want.

I have MovieClip A on stage, that when the user rolls over it another MovieClip (B) is added above it to the stage (it's not added as a child of Movieclip A). Now, when the user rolls over this newly added clip, it triggers the roll out event of the clip 'below' it. So, how can I prevent this from happening ?Basically, it's a movieclip that displays a button when rolled over and hides it when rolled out. I need the roll out NOT to be triggered when the user rolls over movieclip B.

View 1 Replieswhen handling data, i always have to write the following:
var dataSourceRequest:URLRequest = new URLRequest("/path/file.xml");
var dataSourceLoader:URLLoader = new URLLoader(dataSourceRequest);
dataSourceLoader.addEventListener(Event.COMPLETE, handleDataSource);
while i can understand the usefulness of these 2 objects and event listener being separate, since they often work with each other i'd like to know if there is a method that will combine them all? the closest i can get is this, but it's a bit pointless/nesting:
var dataSourceLoader:URLLoader = new URLLoader(new URLRequest("/path/file.xml"));
dataSourceLoader.addEventListener(Event.COMPLETE, handleDataSource);
what i'd really love would be something that automatically combines the URLRequest, URLLoader and completed event listener like this:
var dataSource:Whatever = new Whatever("/path/file.xml", handleDataSource);
I have a queue of messages that I would like to send to a URL and I would like to remove messages from that queue only after I am sure they have been successfully sent. To do this I need to know in the COMPLETE event for the URLLoader exactly what data was sent so that I can remove the correct message from the queue.That is if I have something like this.
var urlRequest:URLRequest = new URLRequest(targetUrl);
var urlLoader:URLLoader = new URLLoader();
urlLoader.dataFormat = URLLoaderDataFormat.TEXT;

Is there a way to cancel a netstream publish from flex to a flash media server?
The issue is I have code where I can Start/Stop a recording to my Flash media server. However in my front end I have a cancel button which allows the user to cancel the current recording and all this code essentially does it close the netstream. But the issue is it still creates the file on my flash media server even though the user has canceled the stream. Is there a function that I can call that will clear up the stream and remove the file that was created?
So the real problem is the lack of an onReleaseOutside function. I found some examples of how to bypass this during a drag function but it was not applicable for a text input.The problem is that when a user selects some text in textinput and mouses off the application area and then mouses up, I'm getting a problem that the textinput keeps thinking that the mouse down is actively selecting text in the textinput and continually overwrites the characters being entered in the textinput. in the search bar of the live store on the page, type some text, then highlight it all and don't let up on the mouse until you are outside the store.I finally hacked some junk together so I can tell if the mouse goes off the stage using some code like.
var x = stage.mouseX;var y = stage.mouseY;if(x < 0 || y <0 || x >stage.stageWidth || y > stage.stageHeight)I'd like to just make the textinput stop thinking it should be highlighting text so that even if the user scrolls out of the applet and mouses up that the text input still overwrites what is in the search bar and functions as normal.

I've got a Glow effect (glowIn) being applied to an object on the roll over which has a startDelay applied. I have another glow effect (glowOut) on roll out. If the user mouses out of the control during the startDelay of glowIn, I want to cancel the effect. How do I do this? In this instance, I'm using a glow effect with a startDelay of 300ms. I want a short pause before the item actually shows the effect, but I don't want the effect playing if the user mouses out during this time. I'm setting the properties as follows:
component.setStyle("rollOverEffect", glowIn);
component.setStyle("rollOutEffect", glowOut);
I don't think it matters much, but the component in question is a Series within a chart that gets created at runtime so I would prefer a solution in actionscript rather than mxml if possible.
Trying to detect a browser close event and send some data to the database when the user closes the browser window...but can't seem to get it to work.[code]
View 6 RepliesIn my Flex app I give the user the ability to open up a new item form ( s:Panel ) and create multiple items on the page.Sometimes for some odd reason bringing up the panel (simple task) seems to take a really long time to load (like 30 seconds or so) However, the weird thing is that if right after I click to open I navigate away from the Tab and back again to the Flex app tab it shows up right away.
I'm not sure if this has to do with refresh rate or some setting or is it general performance/memory issue with my app that I have to consider. When the application work it works fairly fast which is making me think it's not memory/performance issue.

I have a VideoDisplay instance playing some video. When I click on the video slider (also my component) the property videoDisplay.playheadTime is set and the videoDisplay.state goes from 'playing' into a 'seeking' state for a brief moment (the videoDisplay seeks for a new position and then plays the video again). Intended bevaiour. But if I'm (or any random user) fast enough, I can set the playheadTime again while the player is still in 'seeking' state. When repeated several times every click is enqueued and the videoDisplay jump on every place of the video I have clicked(this is happening in an interval about 10-15 second after my last click). When I use live dragging the videoDisplay, overwhelmed by seekings, goes into 'error' state.My question is - is there any way to cancel seeking state of the VideoDisplay class? For example player is in 'seeking' state, I set playheadTime, and the player forgets about last seeking and try to find the new place of the video.
