  The paper “Application-Specific Attacks: Leveraging the ActionScript Virtual Machine” written by Mark Dowd in which he describes various techniques that promise to open up a class of exploits and vulnerability research previously thought to be prohibitively difficult.

  toString() vs xmlToString()

  29.01.08 | Permalink | Comment?

  I don’t know if you got in trouble when working with xmls but recently I found a bug (or a feature). Some differences when using toString() and/or xmlToString().
  Take a look a the following code:

  public var test1:XML = new XML("
  <permissions></permissions>
  ");
  public var test2:XML =
  <permissions></permissions>;
   
  public var test3:XML = new XML("
  <permissions>
  <test1>test</test1>
  </permissions>");
  public var test4:XML =
  <permissions>

  Deep Object Copy

  25.10.07 | Permalink | 1 Comment

  I wanted to write a few words about the deep object copying in flex (aka as making an absolute identical replica of an object no matter it’s class).
  There is a function in the flex API called ObjectUtil.copy This is a very nice function but the problem is it cannot work on all object classes. […]

  Constant XML not so constant?

  25.10.07 | Permalink | Comment?

  It seems that the constants behave strangely in Flex.
  Here is why:

  public const X:String = "X";
  public const Y:int = 101;
  public const NotSoConstant:XML = …some random xml…

  Now here comes the fun part:

  var x:string = X;
  x = "aaa";
  trace(X + ":" + x); // X:aaa
  var y:int = Y;
  y = 10;
  trace(Y +":" + y); //101:10
  var constantOrNot:XML = NotSoConstant;
  constantOrNot = …another […]
