Title Body

I'm trying to call a Flash (AS3) function from Javascript. When the code runs, I get the error "Error: uncaught exception: Error calling method on NPObject!" From my day's worth of googling around, this seems to be be a security matter, and I've done everything I can find, but the error still comes up. Some details: * This happens with both Flash 9 and Flash 10 players. * The swf is in the same domain as the php file that loads it and that contains the javascript that's trying to call the Flash function. * I'm using sfwobject2.2 to load the swf file, like so: var flashvars = {}; var params = {}; var params = {menu: false, bgcolor: "#ffffff", allowScriptAccess: "always"}; swfobject.embedSWF("/path/to/swf", "id", "480", "310", "9.0.0", null, flashvars, params, attributes); My Flash movie is doing the allowDomain thing, correctly as far as I can tell: Security.allowDomain("www.mydomain.com"); * I know that the ExternalInterface.addCallback is set up properly -- when I disable it, I get a "no such function" error instead of the NPObject complaint. This is driving me completely crazy, and I just can't figure out how to correct it. Any advice out there?
