Flash Island: Change values during initialization

[Former Member]

Hi @all!

How can change the values of an ArrayCollection during initialization?

Here is my code-snippet(this is just an example):

[Bindable]
public var dataSource:ArrayCollection = new ArrayCollection();

public function initApp():void{
FlashIsland.register(this);

showMessage();
}

public function showMessage():void{

for (var j:uint = 0; j < dataSource.length; j++) {
    Alert.show(dataSource[j].ID;
}

}

The error message is: Error #1009: Cannot access a property or method of a null object reference

Is it posible to access a dataSource with a timer-method? Or how can I change the properties of a dataSource without using click-Events?

Thanks for your help,

Dirk

by the time your showMessage() called the datasource is empty.

data passed to flash island from web dynpro is asynchronous in nature.

create a public set and get functions for the variable dataSource in the set Function call showMessage() method
