[flexcoders] ARGH shared object array -- getting data

[grimmwerks]

This is driving me nuts -- an onSync of a shared object where  
'history'  is an array -- I can the listing of the array, and I get  
the length of the arraly, but I can't get each object in the array --  
what am I doing wrong?!??



private function chatSync(event:SyncEvent):void{
var arr:Array = new Array();
arr = so_Chat.data.history;
Alert.show('array ' + arr);
var ln:Number = arr.length;
Alert.show(length:  + ln);
var ob:Object = arr[Number(ln)];
Alert.show(ob.message);
Alert.show('message  ' + arr[ln].message);
}

var ob:Object = arr[Number(ln)] should be var ob:Object = arr[ln-1] 

You don't need to cast the ln variable and arrays are indexed from 0 so the 
last value is at length -1.

[Tracy Spratt]

The .length of an array is always one grater than the last element
because arrays are zero based.  Try:

var ob:Object = arr[ln-1];  //returns the last element in the array

And if you think zero-based array indexing is crazy, consider Edsger
Dijkstra's short essay in favor of it:
