LocalConnection PROBLEM!

1

I have 2 swfs that comunicate with LocalConnection.

It works fine when I have open that tab but if I’m in a different tab and the localConnection it’s working it throws me an “error”.

Any ideas?

function callPlaylist()
    {        
        var randomString:String =  _root.random_for_this_page;        
        _root.debugger.text += " intra2 " + randomString;
        //Sending        
        sending_lc = new LocalConnection();        
        sending_lc.parent = this;
        sending_lc.onStatus = function(infoObject:Object) {
            switch (infoObject.level) {
                case 'status' :
                    _root.debugger.text += "LocalConnection connected successfully.";
                        break;
                case 'error' :
                    _root.debugger.text += "F: " + this.parent.callPlaylist;
                    this.parent.callPlaylist();
                    _root.debugger.text += "LocalConnection encountered an send error.";
                    break;
            }
        };
        try{
            sending_lc.send(randomString, "recievePlaylist", "amTerminat");
        }
        catch(e){
            _root.debugger.text += "error";
        }
        //_root.debugger.text += randomString;
    }

This is the send code where i recive the error.
