Flash :: Flex - Debugging Through Via Browser - Security Context Error
Mar 14, 2011
I am trying to use a browser to debug my flash app as it needs External Interface. But whenever I try to attach the Flex Debugger to the browser running Flash app, it shows
SecurityError: Error #2000: No active security context.
I already checked the other question with same title as my error but changing code is not the solution here as it is an existing code and I don't get this error while using a debug version or when I am not running connected to a debugger.
I recently had this vague error happen to me with the use of LocalConnection. It happened every time I tried to connect and send data to another swf. Doing an internet search came up with little results pertaining to LocalConnection and this error and the response some people had were just ridiculous. Apparently this error pertains to image loading and fileReference also, just not in this case. My sending code works fine, even the event.level returned as status which means the other swf got the message, however a trace in the other swf callback function did not show, telling me the callback never triggered.

Now the code I have inherited for this project is huge so I have no idea where the issue could be. I already knocked out a few security issues by embedding my xml and css during compile, and I've reached a dead end.I do load swfs dynamically but everything is local to the main swf. Now I should point out that the customer is loading the swf by simply putting the address of it on a file server into their browser (its not in a web page - yes I know this is bad practice but its what they want).
I am trying to load a swf file which contains xml based image gallery on 25th frame of the timeline inside flash professional cs5.5 using actionscript 3. while doing so i'm getting this error "SecurityError: Error #2000: No active security context". Below is the as3 code:
I have this code that is supposed to pull a thumbnail image from a remote server and return it to be displayed in Flex. my code is throwing "No active security context" errors.fter searching I saw a trick with setTimeout that is supposed to fix this, but it isn't working for me.Here is the Code in Flex 4.0 (Note: File is a custom class)
public function getThumbnail(file:File, callBack:Function):void { // only for image files if (file.mimeType.indexOf("image") > -1) {
[code]....
And I modified the code in my action script file to
public function getThumbnail(file:File, callBack:Function):void { // only for image files if (file.mimeType.indexOf("image") > -1) {
[code]...
I still get the "No active security context" error in Firefox with the debug version of Flash Player.
I'm getting this error intermittenly when I'm testing a web project locally:
SecurityError: Error #2000: No active security context.
I -think- it's an issue loading an image but the trace statements clearly show it's being loaded, report the correct dimensions, etc. I have it looking for both Event.COMPLETE and IOErrorEvent.IO_ERROR sniffing and Event.COMPLETE loads just fine. However the image is never displayed.
Certainly could be another part of the code but the error seems very general. Anyone have any idea what it really means? I thought as I tested that choosing a local sandbox would choose a security context.
I try to "catch" this error when I'm loading some images.The following code is an test-case for my problem to secure that there are no errors in the surrounding code.
I'm working on an interactiv-movie with many images and movies which are loaded dynamically in the application.In this snipped I generated the worst case in my application (try to load an image that not exits).When I run this code I get the trace "SecurityError: Error #2000: No active security context" and not the trace of my the Listener.
I'm having trouble with an AS3 AMF RemoteObject request that is hosted on App Engine. I have a crossdomain.xml file in the root of the domain, and also one at the remoting endpoint.Here are the contents of the root crossdomain.xml:
Loading the swf file and testing it on my machine works just fine... I think that may have something to do with me having the debugger version of Flash Player. When I push it up to App Engine to make it public, other clients access it and get a Client.Error.MessageSend Channel.Security.Error error Error #2048 url: http:[url].......I am using Flex 4 beta, and the App Engine Python runtime. I have tried full wildcard in the crossdomain, and even accessing the data endpoint at a relative URL so as to avoid this error.
I get following error: Error #2044: Unhandled securityError:. text=Error #2048: Security sandbox violation: [URL] cannot load data from 192.168.3.5:4854. at TicTacToe_fla::MainTimeline/TicTacToe_fla::frame1() ". I tryed to solve this problem about 3 hours, but I failed I have the file crossdomain.xml in the same folder like my .swf file on the server with this content:
I tried to deploy my otherwise working flex app on a web server (tomcat 6).It threw a Channel.Security.Error.After some research, I became aware that flash movie loaded from flash_movie_domain will not be able to load resource from any other domain.Some suggested adding a crossdomain.xml.However, the crossdomain.xml route doesn't quite make sense.In this case, I am loading resources from a third party web site.My understanding is that I need this third party website to include a crossdomain.xml on their root directory in order for app to function.The third party web service is provided as is. I will not be able to change what's given. Since the third party is providing public access, it already explicitly give permission to the general public. Adding a crossdomain.xml to their root seems to be a redundant act?
When I am debugging broken code, after a while the browser announces that the Flash plugin has crashed, and I can't continue debugging my code. Can I prevent the browser from killing Flash?
An Adobe FLEX 4 object loads from a webpage and runs in the browser. The connection between browser and server is secured using SSL over HTTP (HTTPS) with a secure certificate from a valid Certificate Authority.
Can FLEX code read the secure certificate information and retrieve information such as to whome the certificate was issued, when it is valid, and for what domain it was issued, etc. ?
I am very new to flex, i have created a simple login page in flex and created a webproject in Eclipse having a jsp page. i have put that jsp page in tomcat webapps. Now when i run an application of login from FlashBuilder it runs fine as i have given the ip e.g [url]... and passing it as a url in HttpService and it worked fine. but when i put my login.swf file in webapps same in that folder where that jsp resides and un e.g [url]... it displays the page but when i click on the login button it gives me with this error "Security error accessing url"
I am getting a strange problem while I am making my release build swf.The swf is supposed to make some internal server calls and then display the data and also play it.When I make a release build swf and excute it, while making server calls it throws exceptions likeSecurityErrorHandler: [SecurityErrorEvent type="securityError" bubbles=falsecancelable=false eventPhase=2 text="Error #2170: Security sandbox violation:file:///Path to the swf/WebPlayer.swf cannot send HTTP headers to **Method Name to bring data from the server***]And after this nothing can be done as everything depends on the data from the server..I have updated my cross-domain.xml on the server to support the master-only policy file but that also didnt ..My cross-domain.xml is
When I try to request a token from Twitter:[code]The weird thing is that it doesn't happen when I run my App in Debug mode (from Flash Builder) it just happens when I call my application from localhot:3000 (as I'm using Rails)!
I am encountering a weird problem. I have a flex application that calls a HTTPService from another domain to retrieve some data. I have created a crossdomain.xml in my flex application with <allow-access-from domain="*"/>.
When i run my application http:[url]...., i can retrieve the data without error.But if i run my application http:[url]....., i encounter the Channel.Security.Error.
I had this error in a Flex Application that I couldn't figure out. Every time the app attempted to access the Web Service it returned the error Security Error Accessing URL.
I am building a little Flash app that will consume some web services over HTTP. When I am in Flexbuilder and run my app there, it works fine. When I goto to my FlexBuilder project on my OS and double-click on it, it works fine. When I zip up my bin-debug file, I get this error:
So I googled that and got information on about the crossdomain.xml file. Well, I can't put a crossdomain file in the service I am calling, but I can put one somewhere else. So I put the following lines in Flex app:
i need to connect to two different domains from a single flex application. the problem is the domain other than the current hosted domain is unable to login. letz say i hosted the application at LOCAL server. im able to login to the local server . From the existing application i need a login to the MAIN server too. The problem comes up here. flash security is not allowing login to MAIN server. in crossdomain we allow-access-from MAIN server. but i want access to the MAIN server from LOCAL server. is ther nything i need to put extra in [URL]?
I am trying to access instagrams API with FLash, I keep getting a "Security sandbox violation: cannot load data from https:[url]....? client_id=...etc" but it works in the IDE. It is loading the cross domain policy file from https:[url]....and I have security allow [url]........ in the swf.
I am working with a project that is developed in the flash environment, but I love the flex/eclipse debugger in that i can throw a breakpoint in and inspect the vars that are present. Is there a way that I can debug flash in the flex environment?
I have (of course) googled the subject and found that there are several posts on the topic but they are incomplete, missing images, or not working in my environment.
m working on an Adobe Flex application that loads lots of Flex Modules and other Flash sub-applications and Flash resources. Each time one successfully loads the flashlog.txt and Flex Console show a trace like "[SWF] filename.swf - [filesize] bytes after decompression". Specifically:[SWF] Main.swf - 1,361,299 bytes after decompression [SWF] core/Core.swf - 516,390 bytes after decompression
I don't want to disable traces because I am debugging, but these traces are rather noisy. How can I suppress only the [SWF] loaded traces?
I tried to search, but couldn't find anything on the topic. In many languages in eclipse you can execute code in the middle of debug session. Usually it's done through the console.
Is there a way to do the same thing in the Flash Builder? EDIT: Ok, i'll to explain better. Is there a way to execute some code in the middle of the debug session? Like in python you can type in console in pydev(eclipse) when the program is paused(being debugged) and run any code you want.
