Question

Environment: Flex 3.6

Look at this piece of code:

    var arr:Array = new Array()
    var t:Object = {number:"12345", id:"Public"};
    arr[t] = "Hello";

    for (var z:Object in arr)
    {
        if (z is String)
            trace("STRING");
        if (z is Object)
            trace("OBJECT");
        trace("z.number = " + z.number);
    }

output:

STRING
OBJECT

then crashes on the last trace() call with the error:

ReferenceError: Error #1069: Property number not found on String and there is no default value

Isn’t the Object supposed to preserve the name of fields?
What i’m doing wrong?

Answer 1

In the for(var key) loop for the Array object key is always String. You can use Dictionary then key will be the type of Object and your code will works:

 var arr:Dictionary= new Dictionary()
