I think I have a solution to my refresh problem.
I had tried this in my real project, but didn't really try it in my
small example that I sent to the message group. Perhaps I had a typo
or there was some other change that seems to make it work now, but
here is my solution:
// Basically, in the addRow function, dispatch an event that
// an item has been added to the collection. In my project,
// I hadn't included the event.location, but now that I include
// that it works.. and you don't even have to click on the header
// to see it!
private function addRow():void
{
if (frmName.text != "")
{
var newEmployee:Object = {name: frmName.text, email:
email.text, phone: phone.text};
var location:int = employees.length;
employees[location] = newEmployee;
var event:CollectionEvent = new
CollectionEvent(CollectionEvent.COLLECTION_CHANGE);
event.items = new Array(newEmployee);
event.kind = CollectionEventKind.ADD;
event.location = location;
ArrayCollection(dg.dataProvider).dispatchEvent(event);
}
}
