  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>

  RSL further details

  08.01.08 | Permalink | 1 Comment

  As I have played with RSLs more I saw something surprising: If I compile the swc into a swf the resulting swf is bigger (almost twice) as it should have been. When you use compc to create a SWC, the SWF inside the SWC contains a lot of unnecessary stuff when used as […]

  How to reduce the size of any flex app using RSL

  08.01.08 | Permalink | 1 Comment

  As you saw in the previous posts you can use RSLs to reduce the size of a flex application.
  If you use mxml in your application you should know that behind the scenes Flex will include in the project a lot of classes and controls (some of them you do not even want). You […]

  First step is to create a new “Flex Library Project”. Write all the code you want to have in it. Then in your main application […]

  Deep Object Copy

  25.10.07 | Permalink | 1 Comment

  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 […]
