Flex :: File Upload - 4 FileReference With Firefox

May 11, 2011

I'm trying to perform a file upload using a FileReference from a Flex app running in Firefox 4. However when I attempt to call the upload() method, the Filereference throws an IOError with the following Error #2038: File I/O Error. URL: [URL] If I don't explicitly add a listener for the IOErrorEvent, then I get a Flash player popup stating SecurityError: Error #2000: No active security context.

The request doens't even hit my server (I can verify by placing breakpoints in the Java code and watching the HTTP Requests that go out using HTTPFox), so it seems to me that this is a client side issue (right?). I've done some searching for the problem on google and the suggestions included wrapping the upload() call in a timeout/callLater, and attempting to attach the sessionId to the request (since Firefox creates a new thread for the upload and doesn't attach the proper cookies). Neither of these approaches has worked for me. I don't experience this problem with Internet Explorer, only Firefox.



Flex :: File Upload - FileReference Doesn't Work With NTLM Authentication?

Jul 15, 2011

We use the FileReference component to upload file in Flex. But if the application is deployed within an environment having NTLM authentication (Windows Integrated Authentication), the upload capability will not work, and each time a message box will be popup asking the user to input credentials.I've queried some resource from internet and it seems this is a bug of FileReference component.

Flex :: Use The FileReference.upload() Function To Upload Files To Sharepoint Or Have To Use The SP Web Services

Feb 5, 2010

Can you use the FileReference.upload() function to upload files to Sharepoint or do I have to use the SP web services? This is without adding your own ASP.NET Web Services, just using the built in SP Web Services.

Flash 10 :: FileReference Upload Not Working On Firefox 3.6.6 Flash Player 10.1

Jul 14, 2010

I have an app that uploads pictures to the server. When I upgraded Firefox 3.6.6 FP to flash player 10.1 the uploaded stopped working. It still works perfect in other browsers. It works fine in Firefox 3.6.6 but different Flash player version. I did some debugging and noticed that it works fine when I run it in my development environment (Localhost). In the production server it returns I/o Exception but it doesnt make sense because it works for other players and also the file is there. I changed the permissions on the file to 777, the allowScriptAccess to always, tried to make the php path absolute also and no luck. The php file does not use sessions or cookies.

Flex :: FileReference And HttpService Browse Image Modify It Then Upload It?

Sep 23, 2009

I am trying to do an image uploader, user can:

- browse local file with button.browse

- select one and save it as a FileReference.

- then we do FileReference.load() then bind the data to our image control.

- after we make a rotation on it and change the data of image.

- and to finish we upload it to a server.

To change the data of image i get the matrix of the displayed image and transform it then i re-use the new matrix and bind it to my old image:

private function TurnImage():void
//Turn it[code]...........

Now the mater is that i really don't know how to send the data as a file to my server cause its not stored in the FileReference and data inside FileReference is readOnly so we can't change it or create a new, so i can't use .upload();.Then i tried HttpService.send but i can't figure out how you send a file and not a mxml.

Flex :: Incorporate FileReference Method Like Upload Into A Cairngorm Architecture?

Jan 14, 2010

how to incorporate FileReference method like Upload into a Cairngorm architecture.Specifically, I would think to fire an event with the File in it, and that's fine. But how would one then be able to listen for e.g. Progress Events?One thing I thought is to have the delegate fire off progress events that are listened for in the View.

ActionScript 3.0 :: Using FileReference's Upload To Call A PHP Script From One Folder & Upload Elsewhere?

Sep 9, 2009

Okay, so I am calling my scripts from the folder "php/" Thus, my FileReference calls "php/upload.php" to upload. However, my uploads are in "uploads/" and not in "php/uploads". When the PHP script is called, it apparently ignores the caller (the SWF file) and looks for uploads in its own directory (the "php/" folder). It may be a PHP question, but how do I reference the uploads folder as being in the parent directory of the php files in my PHP script?

ActionScript 3.0 :: FileReference Upload Failure

Jul 15, 2009

I got a FileRefrence instance for a simple upload and it did work for some time in the past, but now I just can't discover what made it stop woking. Can anyone help me find it out? To simplify, I took only the necessary code (not working as the full version). Here are some details:

1. I'm using Flash Player 9 (this can't change because it is a part of a bigger project). My current host machine is a Windows Vista one. The sandbox is set to network access.

2. The FileReference calls a simple php script hosted at an Apache server (Linux). The script permissions are set to 644 (it works for file uploads coming from plain html pages) and I set the folder permission to 777 just to avoid any other source of errors. Here is the simple code for the php script:

<?php// receiving variables$uid = trim($_POST['uid']); // just to check for a post variable that  I must send while uploading (won't work even if I revome it) 
// a file to check if the script is really called
$myfile = fopen("upload.txt", "wb");fputs($myfile, "file upload for uid $uid


Just for checking I add a Loader instance and used its "load" method with the same "urlSend" variable. It worked and the php script generated the output file...

After moving a web site to another server flash upload stopped working. After some debuging and isolating the problem I found out that in SWF file (used for multiple upload) FileReference.upload() method doesn't work. URL called by item.upload(_root.uploadScript) isn't called.

Here is the code:


listener.onSelect = function(fileRefList:FileReferenceList){

Now I understand that this is returned because the upload function returned a false, but why is it returning this false. Is this because the URLRequest is wrong or the uplaod file is wrong or something else? I've tried looking all over the web for another case and it doesn't give me one.

I traced using firebug, and flash doesnt even TRY to access the aspx script which uploads.So Im trying to look now for an alternative, preferrably using javascript. Like taking all that upload behavior to be javascript's responsibility rather than flash's responsibility.

ActionScript 2.0 :: FileList/FileReference - Second Files Doesn't Upload

Jan 7, 2009

Once the first file is successfully uploaded and the data is returned from server (onUploadCompleteData), I begin to upload the second file from FileList. Here comes the funny - listeners onOpen, onProgress, onComplete are successfully invoked in Flash, the filereference is indeed the filereference of the second file, size matches. But the onUploadCompleteData is never invoked. I checked in IE HTTP Analyzer and there is a simply no outgoing data (0 bytes), even tho the request is made. So the file "finishes" uploading like nothing would have happened but actually it didn't upload at all.

I tried to add a 30 seconds delay between uploads and that works flawless till now. So I tried, 1 sec, 3, 5, 10... didn't work. I simply cannot let a 30 seconds delay between uploads.

ActionScript Code:
public function upload(file:FileReference){
//IntervalManager.clearInterval(this, "uploadInterval"); <- added interval for testing, works with 30 secs
