SipURI getUserAtHost and getUseratHostPort returning wrong values

[GoogleCodeExporter]

What is the expected output? What do you see instead?

missing user and a ":@<host" is returned instead

What version of the product are you using? On what operating system?
Latest svn

Please provide any additional information below.

s = ":"+this.AT; seems wrong

SipUri.prototype.getUserAtHost =function(){
    if(logger!=undefined) logger.debug("SipUri:getUserAtHost()");
    var user = "";
    if (this.authority.getUserInfo() != null)
    {
        user = this.authority.getUserInfo().getUser();
    }
    var host = this.authority.getHost().encode();
    var s = null;
    if (user=="") {
        s = null;
    } else {
        s = ":"+this.AT;
    }
    s=s+host;
    return s;
}
