And Proxy.as may need to change as well. Can you open an issue on Github so we don't forget?

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 -----Original Message----- From: Alex Harui [mailto:aha...@adobe.com.INVALID] Sent: Thursday, April 11, 2019 10:46 AM To: dev@royale.apache.org 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, -Alex On 4/10/19, 6:01 AM, "spiros" <agg...@novusnet.gr> wrote: Hi, I am trying to make an iteration using the for each.
