I have run into a problem with accessing youtube images. I can access them once but not twice. . Here is the example: http://journeyblueheaven.com/index.php
You can click on "Watch" once, and it loads an XML file from a youtube rss, and diplays the results, including images from youtube. So far so good. But then, but if you click on anything else, it attempts to make the images not visible and triggers the sandbox violation below, which requires me to set a policy flag. This line triggers the error: Main.mxml:173 "mainImgBox.visible = false;" This is not the sandbox violation where my swf cannot access another domain. This issue is similar to the one described on this page: http://www.cynergysystems.com/blogs/page/karljohnson?entry=working_around_security_sandbox_errors Only that page loads images with mxml. The way I am loading the images is with actionscript newImage.source = xml.src; How do I set the policy file flag in this situation, or do I need to load the images some other way ? If I try [Bindable] var loaderContext : LoaderContext; private function imageInit() : void { loaderContext = new LoaderContext(); loaderContext.checkPolicyFile = true; } newImage.loaderContext = "{loaderContext}"; newImage.initialize = "imageInit()" ; I get this error: K:\flex3\jbh\fdjbh\Main.mxml(225): Error: Implicit coercion of a value of type String to an unrelated type flash.system:LoaderContext. Do I have the wrong syntax, perhaps ? The code is here: http://journeyblueheaven.com/Main.mxml SecurityError: Error #2122: Security sandbox violation: BitmapData.draw: http://journeyblueheaven.com/fdjbh.swf cannot access http://2.gvt0.com/ThumbnailServer2?app=vss&contentid=0f9a9bc1bda569e6&offsetms=600000&itag=w160&hl=en&sigh=EMg47-bM9077Aklrd1oumF_zqec.
