• Go through Adobe® Flex(tm) 2 DeveloperExam Guide to get the overall idea of exam.
• Refer Flex 2 Developer’s Guide This will help you to cover all areas of flex.
• Refer Programming ActionScript 3 for High Level reference of ActionScript 3.0

This is just a reference material but you experience will count.

Exam questions are come from four areas mentioned in Developer Exam guide.

1. Flex Application User Interface (UI) Creation
   IF you have played with most of UIcomponent of Flex you can easily answer the questions. But questions will not be straight forward it will be well twisted so it requires good attention while reading question.
2. Flex System Architecture and Design
   You should have really good knowledge of flex component architecture and must know how to created loosely coupled component. You should also know basic UML diagram techniques like Inheritance, Implementing interface etc.
3. Flex Application Programming Fundamentals
   You need to have knowledge of OOPS programming and Core AS3 programming like String, Array etc.
4. Integrating with Remote Data and Flex Applications
   If you have worked extensively with flex but haven’t played much with data integration with flex then this will be very difficult area for you. You have for prepare and practice well to understand RPC services features for flex and have good understanding of LCDS

Reading is fine for certification but after all “Experience Matters”

Flex Visual component are created with the class hierarchy of several ActionScript class to provide more flexibility and add more features at the different level of hierarchy.

Following is a visual representation of class hierarchy of Flex Visual Components:

Object: Object is a Top/Root Level class of AactionScript class hierarchy. | More Info…

EventDispatcher: EventDispatcher class extends object class. EvenDispacher class allows any object on the display list to be an event target. | More Info…

DisplayObject: Display Object class extends object and this is the base class for all objects which can be added in the DisplayList. Display object class allows some properties (x, y, width, height )for components/Objects like MovieClip, Button, TextField etc… | More Info…

InteractiveObject provides some common properties like doubleClickEnabled, focusRect, tabIndex etc… and Events like all mouse Events, Keyboard Events. | More Info…

DisplayObjectContainer: DisplayObjectContainer extends InteractiveObject class and it is a base shell for all containers which adds display objects in the container shell. . DisplayObjectContainer provides some common properties like… numChildren, tabChildren etc… and methods like addChild(), removeChilld() method related to the child display object management. .. | More Info…

FlexSprite: FlexSprite is a subclass of the Player’s Sprite class and the superclass of UIComponent. It overrides the toString() method to return a string indicating the location of the object within the hierarchy of DisplayObjects in the application. The Sprite class is a basic display list building block: a display list node that can display graphics and can also contain children. | More Info…
UIComponent: UIComponent extends Sprite and it is a base class for all Interactive and non Interactive component. The UIComponent class is not used as an MXML tag, but is used as a base class for other classes. | More Info…

Hope this article will help you. Any Comments?

Today morning I have open my flex builder IDE and created a new project. New project creation was giving strange Error “Beta Expired”. My Flex builder status bar was showing “Flex Builder 3 will expire in 39 Days” this seems to be a strange behavior…

Solution:

I found out that I was using Flex builder Beta 2 and adobe has set some date for Flex beta 2 SDK Expiry. (This means Your Flex SDK has expired not Flex builder… ‘Flex Builder 3 will expire in 39 Days’ as mention above…)

To solve this problem I have downloaded new Flex 3 Beta 3 SDK and added to flex builder and compiling my projects with Beta 3 SDK

Now, it works fine… Hope this helps to some one facing same problem.
