Ok excellent, changing from Array to ArrayCollection has solved the problem. Lesson learned :) thanks for the help. --- In flexcoders@yahoogroups.com, "calisza" <[EMAIL PROTECTED]> wrote: > > I've been wondering about that and am in the process of testing this. > Will let you know what happens :). > > Just noticed a typo in my previous post - should read product.images > and not product.VO > > > --- In flexcoders@yahoogroups.com, "jack_freud" wrote: > > > > Could it be that you need to use an ArrayCollection rather than an > > array?

I've been wondering about that and am in the process of testing this. Will let you know what happens :).

[flexcoders] Re: Tilelist, ItemRenderer not refreshing when updating dataProvider
Could it be that you need to use an ArrayCollection rather than an array? I think binding to Array only shows changes if the array itself is replaced, not its items.

[flexcoders] Re: Tilelist, ItemRenderer not refreshing when updating dataProvider
The dataProvider is a property of a Cairngorm VO. So, I have a productVO, of which images is a property (Array), so the dataProvider is product.VO - the thing is, the dataProvider IS being updated, its just the display that's not being displayed. As soon as I select another product, and then switch back to the product in question, or if I scroll up and then down in the TileList itself, the newly uploaded image appears. thanks, Barry --- In flexcoders@yahoogroups.com, "Tracy Spratt" <[EMAIL PROTECTED]> wrote: > > Are you using the dataPrvoider API to update the dataProvider?
