View 2 RepliesI have a Flex web application where I am visualizing data (for different countries) in the form of charts. The data is in the form of CSV files. There are individual files for individual charts i.e. one file has all data pertaining to one chart for all countries.I have a left navigation menu that allows one to see data on a country by country basis. As I view more and more countries, the web application becomes progressively slower till it freezes completely. The problem goes away if I refresh the browser and empty the cache.I am using the URLLoader class in flex to read the CSV data into a string and then I am parsing the string to generate the charts.I realize this is happening because more and more data is somehow accumulating in the browser.
View 1 RepliesI have a NavigatorContent which is displayed when the user selects an item in a DataGrid. This NavigatorContent contains a form and an accordion displaying the related objects.
When the user presses the Save button in the NavigatorContent the form and the children should be saved to the database by calling the server through BlazeDS:
saveObjectToDB()
{
//Map the form values to the object
object.field1 = object_field1.text;
[Code]....
The object that i pass to the accordion children is public and [Bindable] in the NavigatorContent and in the accordion children and is initially passed from the main DataGrid. May this be a problem relating to this issue?
I have encountered an interesting problem when I try to load an .xml file using a URLLoader (within my own custom class). I have several configuration .xml files which I use to configure the application when it launches. For example, in the code below, myCustomLoader is a custom class I wrote that takes an .xml file as a parameter. The myCustomLoader class encapsulates all the instantiation of the URLLoader class and error handling etc. The code below operates as expected, the configuration files load into memory, and they're accessible throughout my App.

View 13 RepliesI am trying to use URLLoader to load an XML file from server (same domain as swf). This should be too simple but I am getting Error #2032: Stream Error.If I trace the HTTP status event it just shows status=0 though I have read that Mozilla doesn't supply status codes to Flash Player so maybe it's not informative.I have sniffed the HTTP traffic with Charles and Flash isn't even trying to load the url - no request is made, so it doesn't even fail.I can browse to the url, which is on an internal url that looks like:URL...I have tried putting a crossdomain.xml in there (with and without a to-ports="8080"), though it shouldn't need one.Neither the onOpen nor onActivate events fire, just one HTTPStatus and then the IOError.I have copied the common URLLoader code from Adobe example, mine looks like this:[code]

View 3 RepliesI'm currently trying to make a fun little SWF that lets the user input the URL of an image online, then play around with that image via filters, painting, etc, and save their finished work to disk. However, I'm running into some issues once I upload the SWF online. My SWF works without any problems at all from the Flash sandbox, but once online there seems to be a problem.To overcome the issue of not being allowed to smooth an image loaded from an external source, I am using a URLLoader with dataFormat set to BINARY to load the image. Then I have a regular Loader loadBytes from the loaded data of the URLLoader. This allows me to apply smoothing and chang ethe bitmapData of the loaded image.
This works for a select amount of images online. The problem here is that for most images, the URLLoader never finishes loading, nor does it produce an error. It doesn't even produce a ProgressEvent. The .load method of the URLLoader executes with error.
Is 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 RepliesI'm creating a website using Adobe Flash Professional CS5. I'm trying to read the content of a text file with URLLoader.load(path) inside a for loop. The path changes every iteration. When I trace the data from the event handler method, it returns only the last path's text file's content. It seems like it's calling the event handler method only after the for has done looping.

var myData:URLLoader = new URLLoader();
myData.addEventListener(Event.COMPLETE, onLoaded);

Wondering if anyone has an incite on this. I have a basic Shell class that I'm using to load in all of my assets including two xml files and one css file. Currently I'm using a single URLLoader to load in the three external files. Through testing (Using FDT Pure in Eclipse 3.3.3, publishing using 'FDT AS3 Application') I'm running into an interesting issue.Basically the first file that I try and load, regardless which xml file or css file, my onComplete doesn't seem to be getting called. But everything runs gravy if I insert this line before beginning my loading:
ActionScript Code:
this._urlLoader.load(new URLRequest(""));
Here's some more of the code:
[code].....
there you are, you set up your AS3 code to load XML via a URLLoader and URLRequest, as normal. You then take your XML file, and upload it to a server. You then run your program, and trace out the XML you receive. So far so great, and you see the results of your XML traced out. Then you change something on your XML, either adding to it or removing a line. You then run your program again from CS5.5, and trace out the XML, and it shows the same results that it did before you made any changes. I deleted the XML file from the remote server, and it is like it stored it in cache, and still able to read it. If I change the url or file name, it gives me an error, which it should.
If I point the url back to my remote XML file, and run the program again, it gives me the XML results I had in the beginning, before I made any changes to it (regardless if the XML file exists). The only fix I have found so far, is closing CS5.5, and reopening, and then it can see the changes. I did that, and it was able to see my XML changes on my remote server, but again, only one time. If I try to change anything, or delete the XML file, it still pretends as if its there, reading the results that it read the first time I run the program. Is this a cache issue? Anybody else experience this? I never remember running into this problem using CS5/CS4/CS3, only CS5.5. Of course, I can test it all locally first, and then upload the XML file to the remote server when I know that no other changes need to be made, but still, this is really weird!
I'm planning to load images via URLLOADER onto the stage.....i want each image to be on a diffrent frame of the main timeline how do i tell each one which frame it belongs to?
View 5 RepliesI understand the Flash and AS3 is single-threaded, at least at the user level. I would like to understand how asynchronous data loading is handled by the Flash player.
For instance, if I run CPU-intensive code that runs beyond the normal frame (lets say it runs on ENTER_FRAME, and consumes 1/4 per call). Does this leave any CPU cycles to load data from a URLLoader?
If http loading is truly synchronous, right down to handling the TCP/IP stack, one would get horrible performance. In Windows programming, I can do http access asynchronously (in which case the Windows libraries are doing either input on a separate thread, or doing hardware-level interrupts to handle the data -- I provide an asynchronous callback that may be on its own thread). Or, I can do synchronous download, in which case there will be hardware buffering, but my application is actively waiting for each buffer of data to be delivered by the hardware/OS combination.
URLLoader is asynchronous, but what does that mean? Does it mean that I can run the CPU and still download data? Or, will my download speed slow to a crawl if my Flash application is under heavy CPU load? Understanding how this works will help me design my product better, which both uses a lot of CPU, and downloads a lot of data (to the bandwidth limit of the network, if possible).
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 :

I have a Flash movie that behaves as follows:Movie loads > tries to load an XML file using URLLoader.load() > uses the data in the XML to load some images into the movie.The requirement was for updates to the XML file to be picked up within 10 minutes, so I have added a querystring parameter to the XML URL which is a timestamp to the nearest ten minutes, e.g.1-40**This all works for me as expected in IE and Chrome, and it works locally for me in Firefox. However, on our production server (IIS) in Firefox, the following behaviour occurs (by observing Firebug):First load:SWF loads > XML Requested and loads > images requested and loadSubsequent page loads:SWF Loads > no request for the XML (no request shown in Firebug)Firebug shows the following information about the XML file from the first successful request:

1 - SWF must have ability to loading binary data from any domain.
2 - SWF cant load policy XML file from url, cause upload form allows me only to upload swf files, so I cant include any other data.
I tried:
Security.allowDomain("*");
But it works only for SWF files.I tried to embed policy XML file:
var dataXML:XML =
<?xml version="1.0"?>
<!-- http://www.foo.com/crossdomain.xml -->
<cross-domain-policy>
[code]....
This will make an security error, if file is from different domain than SWF file.Its possible to get binary data from JavaScript using ExternatInterface in AS3 code.Here is cross-browser library for reading files binary: binary reader and later version jDataView.
I have a small Flash app that generates a security sandbox violation when flash.net. URLLoader() is called.I have been very careful to check for mistakes in my network/security settings, e.g., -use-network=true, cross-domain policy file, Security.allowDomain(), Security.allowInsecureDomain()
, Security.loadPolicyFile(), etc.

Ran 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 1 RepliesI am making rest calls with a urlload.load(urlRquest).
also
urlRequest.method = URLRequestMethod.POST;
urlRequest.contentType = "application/xml";
When I make the calls within the Flash IDE, I get HTTPStatusEvent.status = 400 (or whatever) when an error occurs. And the IOErrorEvent.data contains xml (or sometimes a string).
However, when I run the swf in a browser (Firefox Mac or PC), the HTTPStatusEvent.status = 0, and the IOErrorEvent.data is empty. (Interestingly in Safari Mac, I do get the 400 status, but still no data.)
Since URLLoader is async, how to make sure the order of data from server side is the same as the loader.load() call? In other words, the data order in totalResults is the same order of url-related content?
Following is code snippet:
1.for each(var url in urls) {
loadData(url);
}
2.private function loadData(url:String):void {

I use UrlLoader.load() in my flash app. And I'm handling UncaughtErrorEvent.UNCAUGHT_ERROR to stop the app when an uncaught exception occured. UrlLoader.load() works when you are connecting the internet normally. But if the connection to the internet was lost after your browser loaded the app, SecurityError happens when UrlLoader.load() is called. I can not catch the SecurityError by using try catch and UNCAUGHT_ERROR happens and it stops my app. I don't want to stop the app when UrlLoader.load() failed because I'm just using UrlLoader.load() to log some unimportant information.
And I think timeout error also can be ocurred if it takes a long time to load. And I also don't want to stop my app due to the time out error. How can I solve those problems? And are there more other type of errors which can be ocurred and stop my app?
