Flex :: Send Error Message From Servlet To FileReference When Download?
Jul 19, 2011
I use fileReference.download() to download files. The fileReference send request to java servlet.In servlet, some error may be checked. For example error - 'File not found'. I want to send the error to flex side. I tried lots of methods,but fileReference in flex can't receive them.Such asresponse.sendError(HttpServletResponse.SC_NOT_FOUND, "File not found");r PrintWriter out = resp.getWriter(); out.print("File not found");It seems fileReference can't triggers event 'DataEvent.UPLOAD_COMPLETE_DATA' and'HTTPStatusEvent.HTTP_STATUS'.

I have a collection of Objects in an ArrayCollection in my flex page.
What is the best approach to send this data to a Java Servlet?
The object in the ArrayCollection is a VO that consists of an id and message for now. I want a solution that is scalable in case more properties are added later on.

I recently switch from AS2 to AS3 (too late - I know) and bump into (probably easy) problems now and then. I'm making this preloader in a class - I read that this might not be a good idea to put it in a class (?) - and I'm using a timer in it. But I keep getting this error message after simulating a download:
Code:
TypeError: Error #1009: Cannot access a property or method of a null object reference.

I'm using FileReference to retrieve an exported CSV file from the server. The fileReference.download(url, "myFilename.csv") method call seems to be working and I can download the file.
The only problem with this is that I can't seem to be able to set the file filter. In my save dialog, the file type filter is always *.*, which is really bad. The user trying to save the file has to manually type in the .csv extension. How do I change the filter of the dialog box to only show *.csv and not

I need user download JPEG file from my app, however, when user change the file name the saved file will be downloaded without extension.
For Example: I am using FileReference.download() and set the default filename as "demoPic.jpg" and user's windows system setting control file extension not being shown. So when the dialog opens a download window, only "demoPic" shown as the filename. If user saved file without changing filename, the saved file will be OK. But if user change file name, the download file will be saved without extension. is it possible to add file extension to filename when user forget it by flex code?

Possible Duplicate: losing extension when use FileReference download I'm having an issue that looks common when using the FileReference class in FP10 when saving a file. The whole thing works fine as long as I don't change the default filename. If I do, then I loose the extension of the file... which is annoying >_< I haven't found any "acceptable" workaround, but the posts I've seen are from a couple of months already. So I'm inquiring hoping that something's been done regarding this issue since then =)

I am using a filereference Object to export an excel file from my flex application. I am using fileReference.save() from Flash player 10. I am getting an error if the file i am trying to save is already open. This error is not getting handled even if i put a try catch block. I have tried adding a listener with IOErrorEvent.IO_ERROR. Still the error is happening. This is the Error message i am getting - "Error #2044: Unhandled IOErrorEvent:. text=Error #2038: File I/O Error."

I have a flash app that uses the FileReference download method to serve up download links. Many of the links come from big content delviry networks and a crossdomain policy file is required to avoid a security error. This all works fine. Except for redirects in IE... in FF redirects work.
A typical Charles log in FF looks like this....
Code:
1) 302: download file temporarily moved
2) 302: download file found
3) 200: download file received OK
[Code].....
....the request for the crossdomain policy file is not being made in IE & thus flash blocks access to the download (client closed connection). The flash throws the traditional 2048 security error - which is what I'd expect if no crossdomain is available. It's worth noting that downloads without a redirect work fine in IE, the crossdomain is requested & received.
As far as I can make out there is no way to force "checkPolicyFile" with FileReference - it doesn't take a LoaderContext object. I'm at a loss of what I can do to resolve this without putting a proxy on our webserver (the backend guru will not allow this as the downloads can be quite large & he thinks will end up being a huge bottleneck).

I'm using the FileReference to download a file (using a relative path). If I test it on the .swf on the browser it works. If I compile a .exe projector the download doesn't works.

I need to allow a user to download images from my app, but everytime a user attempts to download, the extension is stripped from the filename I provide.This is only happening in Firefox & IE on Windows. It's working just fine on OSX.
I'm using FileReference.download(), and specifying the filename as "imageX.jpg". However, when the file dialog opens on Windows to save the document, only "imageX" is shown as the filename, and the extension is never saved. In the "Save As type..." field, there is only the "*.*" option available.
The majority of our users aren't technically savvy, so a lot of them don't realize that if they put a .jpg extension on the file they just downloaded, they'll be able to view the image.

I am using this code to download a file from a server (podcast episode mp3) but I click the submit button and nothing happens. The text field shows "Downloading episode X" but nothing happens, no browse-to-save window pops up or anything. Here is my entire code, no external.It simply uses AMFPHP to drawback results to see if the podcast episode exists. If it returns a 1, the fileReference download is triggered. I'm pretty sure the rest of the code is fine, its just the "localRef.download(requestF);" bit that seems to be doing nothing.[Code].....

I've built an audio player that is fed via an xml file. Users can use a 'previous' or 'next' button to select which track to listen to and then play it and this is all fine and works as it should. The problem I have is with the file reference class. I want users to be able to have the option of downloading the track. I can get this function to work once but once you download a track, choose another, then click the download button again I get the error message below:

However, it doesn't work. It works when I put the full absolute address, instead of simply "images/img1.jpg" . Is there any way to use a relative address?!?!? Probably attach the relative address to the URL property?

I am trying to use fileReference.download to allow users to download content from my site. The problem is, when I test it in Flash, it works flawlessly. When I publish it and upload it to my server it doesn't download. It'll bring up the download box... but it wont initiate the download. What I am doing is dynamically creating text boxes using the amount of XML nodes in my xml file. It will then assign the proper download file to that text box/download button.
its just not initiating the download in my browser.

I'm trying to get my flash movie to allow the user to download a file of a specific extension, at the moment i use:
[Code]....
Two problems:
a) If the user changes the file name in the browser before clicking save (and doesn't re-add the .xml extension) then the file is saved without an extension
b) Randomly, tested on two windows xp systems both in IE one included the extension in the filename on the browser download window and one didn't (which doesn't make it clear to the user they have to include the extension as part of the name) but both saved to the correct xml extension file
a) If there is a work around so I can specify the exact file type, in the adobe reference manual it states you can parse in extra parameters to server with the file location to download. How would i do this?
b) If can't do a, how can I get it to always display the extension in the browser download window (unlike in problem b )

why the error message repeats in Flex SDK 3.5 (but not in 3.4) and have a good way to make it stop repeating?

To make this happen, leave the textInput field empty and hit save multiple times. Then mouseover the textInput.

i've got a pic gallery from kirupa which i modified a bit.I've added a download button with filereference. The thing is everthing works when the download button is pressed.But if somebody wants to download a picture and wants to change the name the file isn't recognised because the extension is lost.Flash doesnt read after the dot (example .jpg). If you dont change the name of the file which you save it keeps its extension.
here's my code for the download and the link
Code:
/////////////////////////////////////
// DOWNLOAD CODE
import flash.net.FileReference;[code]....
ive tried to put it like this but it doesnt work
Code:
function downloadPICT(){
fileRef.download(url+download[p]+".jpg");
}
PS download[p] is read from an XML file its the link to the downloadfile, which looks like this
Code:
<?xml version="1.0" encoding="utf-8" standalone="yes"?>

I have a data grid where users can drag columns and reposition them. But there is a strange requirement that some columns should not be draged to the left of some other column. eg, assume the columns are: name, price , start date, end date, The end date should not be dragged and placed before the start date. i.e. The user can have start date, price , name , end date. name, start date, price , end date. But at no point can end date appear before start date. Is there a way to do this flex? Is there a way to know where the user is trying to drop the column and show error message ?
