You need to use something like ArrayCollection which dispatches events. Your
repeater should then pick up the changes and add the new item.

I've done this with an ArrayCollections, but never with an Array. The

public var myArray:Array = ['test1','test2','test3'];
public var myArrayCollection = new ArrayCollection(myArray);
public function addItem():void{
myArrayCollection.addItem('test4');
}

</mx:Script>
<mx:VBox>
<mx:Repeater id="rp" dataProvider="{myArrayCollection}" >
<mx:TextInput id="myRepeat" />
</mx:Repeater>
<mx:Button label="click me" click="addItem();" />
</mx:VBox>
A few caveats...
a) I didn't test this code
b) In my situation, I wasn't adding from the same component that was
displaying things, so the 'add' and 'display were never shown at the same
time. There could have been other code that made the refresh work, but I
don't remember anything explicit.
c) When accessing a repeater element you use currentIndex when it is
repeating, but repeaterIndex after the fact. I haven't found a simple way
to switch between the two of them, but my solution was something like this:
try{
return myArrayCollection.getItemAt(loop.currentIndex );
}
catch (e:Error){
return myArrayCollection.getItemAt(loop.repeaterIndex );
}
I imagine there must be a better way

doesn't work.) I was hoping that updating the dataProvider would add
another item to the repeater...

I have a repeater (adding TextInput fields) that is bound to an
ArrayCollection on my model. I was hoping that essentially I could
add a row by just pushing a value into my ArrayCollection on the
model. However, this isn't working. I assume I need to also
"refresh" the repeater, but can't seem to figure out the best way to
do that.
Thanks, Kevin
