You are a star!
Thanks very much, addItem
on the actual array did the trick, I hadn’t thought about doing it this
way.
This will solve a lot of problems!
Thanks again,
Steve

Array/Dataprovider/Tabbar etc issues.
Hi, i did a simple test (below)
<?xml version="1.0"?>
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml"
>
<mx:Script>
<![CDATA[
var dp:Array = [{ label:"one",
data:"two" },
{
label:"four",
data:"five" },
{
label:"seven",
data:"eight" },
{
label:"ten",
data:"eleven" },
{
label:"thirteen",
data:"fourteen" }];
function doClick()
{
dp.addItem({label:"xx", data:"xx"});
//or uncomment
next 2 lines
//dp.push({label:"xx", data:"xx"});
//dp.dispatchEvent({type:"modelChanged"});
}
]]>
</mx:Script>
<mx:TabBar
id="tb1" dataProvider="{dp}"/>
<mx:List
id="list1" dataProvider="{dp}"/>
<mx:TabBar
id="tb2" dataProvider="{dp}"/>
<mx:Button
label="test" click="doClick()" />
</mx:Application>
Now, if you declare your array (eg dp) at the
application level.
then you could reference it in your components as
mx.core.Application.Application.dp
eg
<mx:TabBar
dataProvider="{mx.core.Application.application.dp}"/>
mx.core.Application.application.dp.addItem({label:"xx",
data:"xx"})
and all components using dp should get updated.

Now what happens
