Strange issue here: I imported an existing project into Flex Builder 3 (a project that was working just fine before) and suddenly I'm being inundated with these SecurityDomain security sandbox violations. The crux of the error is:
*** Security Sandbox Violation ***
SecurityDomain 'file:///D:/ProductMediaVewer/bin-debug/ProductMediaVewer.html' tried to access incompatible context 'file:///D:/ProductMediaVewer/bin-debug/ProductMediaVewer.swf'
Which is repeated 5 times. The crazy thing is that this is a shell of an app, there aren't even any guts to this yet! I can empty the contents of the project .mxml and I still get this error! The only thing that comes to mind, which is bizarre because it didn't happen before, is that the browser is on C: and the app is on D: -- but I've developed lots of apps on D and never had this come up. What is going on here?!
Thank you Alex!! I added C: and D: to the settings in Global Security and that made the sandbox error go away. It is really strange though, in the decade I've been publishing swfs I've never had to add my local drives. Maybe its a Flex Builder fluke, but thanks for helping me make the annoyance go away. Let me know if you come up with any background on the anomoly.
