Isn't an ArrayCollection essentially equivalent to a Query?
An array of objects...
Adobe and Macromedia are the same, CF and Flex sleep together, why don't they
just call it a day?

ArrayCollection is the path to enlightenment, yes, but a
metaphysical nudge along this path is binadability
[Bindable]
public var myArrayCollection = new ArrayCollection( myArray);

I've done this with an ArrayCollections, but never with an
Array. The code would be something like this:
<mx:Script>
<![CDATA[
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.currentInde x );
}
catch (e:Error){
return myArrayCollection. getItemAt( loop.repeaterInd ex );
}
I imagine there must be a better way

here is a little test to
illustrate what I am trying to do (except it doesn't work.) I was
hoping that updating the dataProvider would add another item to the
repeater...

myArray:Array =
['test1','test2'
,'test3'];
public function
addItem():void{
myArray.push('test4');

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
