问题
When running flash components that use localConnection within an HTML container, I get the following error in a popup box (flash player is the debug version):
Error #2044: Unhandled SecurityErrorEvent:. text=Error #2047: Security sandbox violation: LocalConnection.send: 127.0.0.1 cannot access
回答1:
Changing the page's URL from http://127.0.0.1/ to http://localhost/ solved the problem.
回答2:
// add this line after the instanciation aof the receiver file
receiveSwf_lc.allowDomain("localhost");
// or whatever domain you like, use * as wildcard to allow any domain name

You can add a hosts file entry and point it to 127.0.0.1 as well.
