Hi Alex ,
You have right the mx.collection.Arraylist and
org.apache.flex.collections.ArrayList in flex didn’t iterate in flex.
I already included the js code for the three cases ( it is on bottom of email).
I don’t know if it helps but in one of my tests for the ArrayCollection I
extend the class and add a method with name propertyNames (*1).
in this case the iteration work fine.
(*1)
public function propertyNames():Array
{
var array:Array = new Array;
for (var i:int= 0 ; i< length;i++)
{
array.push(this[i]);
}
return array
}
Best regards
Spiros

Subject: Re: For each iteration in ArrayList and ArrayCollection
Hi Spiros,
Could you use for-each on an ArrayList in Flex? I didn't think it would work.
I thought it only worked on ArrayCollection in Flex.
What is the output JavaScript for your sample code when you use
ArrayCollection? In Royale if you interate on XML, or a Proxy like
ArrayCollection you have to make sure the compiler knows it is XML or a Proxy
subclass. If it thinks items is an Object it will not generate the right code.
HTH,

Hi,
I am trying to make an iteration using the for each. The property class is
a simple class with two fields.
I test the iteration with this classes :
1. org.apache.royale.collections.ArrayList error message: TypeError:
propertyClass is undefined
2. mx.collections.ArrayList error message TypeError: propertyClass is
undefined
3. mx.collections.ArrayCollection error message TypeError:
foreachiter0_target.propertyNames is not a function
the as3 code is:
private function iteration():void
{
var object:Object = new Object;
for each (var propertyClass:PropertyClass in items)
{
object[propertyClass.name] = propertyClass.index;
}
}
Thanks in advanced
Spiros
ps: The js generated code for this 3 classes
