    Security Sandbox Violation


      I have a Flash application in "domainA" and I'm running it from "domainB". The Flash application loads fine and runs. However, the history manager no longer works. When the user clicks on the back button they get:


      *** Security Sandbox Violation ***

      SecurityDomain 'domainB' tried to access incompatible context 'domainA'


      If I run the flash application within the same domain, everything works fine. I added the following in the flash application:




      And that still doesn't work.


      Thanks in advance....

              That probably requires allowScriptAccess

                Already set and doesn't work.


                In Main.mxml:


                <mx:Application xmlns:fx = "http://ns.adobe.com/mxml/2009"

                                xmlns:s = "library://ns.adobe.com/flex/spark"

                                xmlns:mx = "library://ns.adobe.com/flex/mx"

                                layout = "absolute"

                                width = "100%"

                                height = "100%"

                                preinitialize = "preInit()"






                            private function preInit():void









                In the html page:


                            var params = {};

                            params.allowscriptaccess = "always";



                            "Main.swf", "flashContent",

                                "100%", "100%",

                                swfVersionStr, xiSwfUrlStr,

                                null, params, attributes);




                <?xml version="1.0"?>


                    <site-control permitted-cross-domain-policies="all"/>

                    <allow-access-from domain="*"/>




                I've tried everything I can think of, spent over 1 day trying to resolve this issue and nothing seems to work. The next thing I am thinking is that this might be a Flex 4 issue.

                  As I suspected, it is a Flex 4 issue. I created 2 simple Flex apps one in Flex 3 and the other in Flex 4. The browser back/forward buttons work fine in Flex 3 but no longer works in Flex 4.

                  They listen to the BrowserChangeEvent.BROWSER_URL_CHANGE. Did this change? I could upload the sample apps if needed.

                    Simplify your test case as much as possible.  Flex 3 uses a different swf

                    embedding script than Flex 4 so double-check that you have set

                    allowScriptAccess properly.  And allowDomain in the SWF.

                      The test cases are really simple. I wanted to zip up the projects and upload them, but I don't see a option here to upload.


                      Yes, they allowScriptAccess is set to always in both places projects and the html generates correctly.

                        I also tried to register with the Flex bug management system....I'm still waiting for a email to confirm my account.
