I'm trying to map a Vector of Strings and assign the returning Vector to a variable, but the result from the map() is null...
If I use an Array instead of a Vector.<String> the problem disappears...
Here's the code:
private var validPhotoExtensions:Vector.<String> = Vector.<String>(["jPG", "jpeg"]);
var toLowerCase:Function = function(item:String, index:int, vector:Vector.<String>) : String
{
var str:String = String(item).toLowerCase();
return str;
};
var bla:Vector.<String> = new Vector.<String>();
// The value of bla will be nul...
bla = validPhotoExtensions.map(toLowerCase);
