You can pass an array into a List or ComboBox and it will display it.

But here's the situation: inside a custom component, I am displaying the contents of an Actionscript Object (custom class). I have a DataGrid bound to an ArrayCollection which is one of the properties of the Object. The source array contains Value Objects which are populated by a RemoteObject call to ColdFusion. One property of the Value Object is also an array. So it looks like this: Object:Config has an itemAC property. The itemAC contains an array of Item objects. The Item is the VO. The Item contains an options:Array. The options:Array contains optionItems. One of the properties of an optionItem is an optionName. So the DataProvider for my DG is {config.itemAC}. This is fine. However, I need one column of my DG to show a simple list of the associated optionNames. I can't make the options:Array within the Item VO an ArrayCollection, or Flex will not translate the objects sent by ColdFusion into a typed AS object. So I have created an itemRenderer for the DG, in which I loop over the options:Array in the current row's data and build a string. But of course, this has to be updated as options are added to the array. I have tried placing a datachange listener inside the renderer itself; but when it fires, it's creating an infinite loop -- to the point where I can't even debug it. At this point, I'm basically spinning wheels and I could use a little direction. I realize this whole problem sounds pretty vague; but any advice would be appreciated. -- Thanks, Tom Tom McNeer MediumCool http://www.mediumcool.com <http://www.mediumcool.com> 1735 Johnson Road NE Atlanta, GA 30306 404.589.0560
