Flex 4 ACE Questions

Passed ACE Certification with Flex4.

The differences of Flex3 and Flex 4 certifications
1/ more questions – 59 questions (previously 50)
2/ more time – 90 minutes (previously 60 min) Don’t bother about time factor you will have at least 30 minutes spare time for review.
3/ UI have more share among questions 35 %
4/ In Flex_Exam_Guide – They didn’t mentioned about LCDS, but we got Questions from LCDS too.

1/ Do use attest, as it is the only resource we have for mockup
2/ Unlike Attest the questions will be in shuffled order
3/ While you attend ACE, don’t forget to use “Flag for review”, whenever you have doubt on your answer.
4/ The Questionnaire will be different for everyone

The below are some important topics, these areas required to be refreshed before attempting ACE.

Using IViewCursor for Navigation

The Below code is example for using IViewCursor for ArrayCollection Navigation

<?xml version=”1.0″?>
<mx:Application xmlns:mx=”; initialize=”run();”>
import mx.collections.*;
private var myCursor:IViewCursor;
public var myAC:ArrayCollection;
public var myArray:Array = [ { label:1, data:”One” }, { label:2, data:”Two” }, { label:3, data:”Three” }, { label:4, data:”Four” }, { label:5, data:”Five” },
{ label:6, data:”Six” }, { label:7, data:”Seven” }, { label:8, data:”Eight” }, { label:9, data:”Nine” }, {label:10, data:”Ten”}];

public function run():void {
myAC = new ArrayCollection(myArray);
var sort:Sort = new Sort();
sort.fields = [new SortField(“label”)];
first.enabled = false;
back.enabled = false;
public function countLast(theCursor:IViewCursor):int {
var counter:int=0;
var mark:CursorBookmark=theCursor.bookmark;
while (theCursor.moveNext()) {
return counter;
public function countFromSelection():void {
var count:int = countLast(myCursor);
ta1.text = “cursor is at: ” + myCursor.current.label;
public function nextCollection():void {
if(! myCursor.afterLast) {
ta1.text=”cursor is at: ” + myCursor.current.label;
public function backCollection():void {
if(!myCursor.beforeFirst) {
ta1.text=”cursor is at: ” + myCursor.current.label;
public function firstCollection():void {;
ta1.text=”cursor is at: ” + myCursor.current.label;
public function lastCollection():void {;
ta1.text=”cursor is at: ” + myCursor.current.label;
public function navigate(event:MouseEvent):void {
switch(event.currentTarget.label) {
case ‘first’:
case ‘back’:
case ‘next’:
case ‘last’:
public function enableDisableButtons():void{
var firstInCollection:Boolean = myAC.getItemAt(0) == myCursor.current;
first.enabled = back.enabled = !firstInCollection
var lastInCollection:Boolean = myAC.getItemAt(myAC.length – 1) == myCursor.current;
last.enabled = next.enabled = !lastInCollection;
<mx:ComboBox id=”myCB” dataProvider=”{myAC}” change=”countFromSelection();”/>
<mx:TextArea id=”ta1″ height=”200″ width=”175″/>
<mx:Button label=”first” id=”first” click=”navigate(event)”/>
