Using a repeater in a custom FileInfo Panel --data binding error

Question

When I developed a custom FileInfo panel in Flex Builder 3, I could use an array to populate a checkBox control inside a repeater, and it worked.
Now, using Flash Builder 4, data binding with <mx:Repeater> doesn't seem to work, resulting in an empty fileInfo panel.
When I remove the dataProvider from the <mx:Repeater> tag, my panel displays, but without the repeater. How can I specify the dataProvider in a different way that works?
Thanks
The code:
<fi:XMPForm
          xmlns:mx="http://www.adobe.com/2006/mxml"
          xmlns:fi="com.adobe.xmp.components.*" width="100%" height="100%"
          label="TestPanel2_1" xmlns:s="library://ns.adobe.com/flex/spark" >
     <!-- Each namespace prefix that is used within an xmpPath-attribute,
          MUST BE registered at the top of EACH panel where it is referenced -->
     <fi:XMPNamespaces>
          <fi:XMPNamespace prefix="dc" value="http://purl.org/dc/elements/1.1/"/>
     </fi:XMPNamespaces>
     <mx:Script>
          <![CDATA[
               import mx.collections.ArrayCollection;
               [Bindable] public var newArray:Array =["One", "Two", "Three", "Four", "Five"];         
          ]]>
     </mx:Script>
     <fi:XMPFormItem>
          <mx:VBox id="primaryFrame" width="800">    
               <mx:Repeater id="myRep" dataProvider="{newArray}">
                    <mx:Label text="{myRep.currentItem}"/>                  
               </mx:Repeater>
          </mx:VBox>
     </fi:XMPFormItem
</fir:XMPForm>

Okay, I may have been making a rookie mistake. I see online reports that you can't bind an array to a repeater (even though it has worked for me).
I've added the following variable to make my array an array collection:
[Bindable] public var newArray2:ArrayCollection = new ArrayCollection(newArray);
After changing the binding of the repeater to the new array and running the build, the fileInfo panel still does not function.
Any thoughts?
