//Very strange / Sehr merkwürdig in Actionscript:
var a:String = '0';
var b:String = '1';
if (a == true) {
trace(a+" is true");
} else {
trace(a+" is not true");
}
if (b == true) {
trace(b+" is true");
} else {
trace(b+"is not true");
}
//Output / Ausgabe/:
//0 is not true
//1 is true
var a:String = '0';
var b:String = '1';
if (a == true) {
trace(a+" is true");
} else {
trace(a+" is not true");

if (b == true) {
trace(b+" is true");
} else {

The same happens with JavaScript.
Try the following:
var a = new String();
a="1";
alert(typeof(a));
// String
if(a==true){
alert(a);
}
else {
alert("this would be expected");
}
// 1
nothing strange .. Jave transform string to boolean without any function - so 1 is == true and 0 is false - so it right ///
if you need to see if string is exist . that ask that // not that it is true o false
if ( a.length > 0 )
