Yeah, it's sounding like a bug to me too. Do your workaround for now and let's see if it's fixed in B2.

Re: [flexcoders] Re: Repeater and Web Services (Flex 2b1)
Hi!
The difference between your code and mine was that I set a temp variable,
made all the changes on the temp, and then assigned the temp to the bound
variable.
I don't know why, but assigning the changed temp variable seemed to react
differently than changing the actual bound variable.
I'm not sure why excecuteBindings did not work for you. It almost
always worked for me.
Are you sure you are getting data back from your service?

Thanks for that.
executeBindings() didn't work though, it just didn't
seem to fire the event. :-(

which I think is the same as your other suggestion. This gives me
a
null error.
Any more ideas appreciated, or is this a bug?
ta,
Tim.

Re: [flexcoders] Re: Repeater and Web Services (Flex 2b1)
Hi!
I know this may not be the "right" way, but you can call
myCategories.executeBindings()
or
I found if I made a new Object added the data to that and then set
the bound object to that:
var tmpArray = new
ArrayCollection();
var lResults : ArrayCollection =
new
ArrayCollection(event.result);
var lIndex:int;
for (lIndex = 0; lIndex <
lResults.length; lIndex++)
{
tmpArray.addItem(lResults.getItemAt(lIndex));
}
tabsDataProvider = tmpArray;
I'm not sure if the above will work some times it did, other times I
had to call executeBindings.

This code:
tabsDataProvider = new
ArrayCollection(event.result);
var lCollectionEvent : CollectionEvent =
new CollectionEvent();
lCollectionEvent.kind =
CollectionEventKind.REFRESH;
tabsDataProvider.dispatchEvent(lCollectionEvent);
causes the same
TypeError: Error #1009: null has no properties.
