You do need to use XMLListCollection to get the ui update. XMLList is ike Array, and does not dispatch the necessary events. Either of the collections, or XML will.

Since this doesn't seem to work we're reserved to throwing events from the component to the list and rebinding the list when that event is caught by the gui, but the whole thing is pretty cumbersome and i think this should work automatically.... what are we doing wrong?

I also have a component with an xmllist property which is marked as [Bindable] in actionscript, i instantiate that component and bind this data property to the list. When i receive data from webservice, i update the xmllist of the component. shouldn't the visual list update as well since it is bound to that component's property? also, i have tried this with an XMLListCollection as well and same result. only if i rebind the list to the component's property do i get the result. what i am doing wrong? is this by design? should there be something else wired or triggered for the updates to occur automatically? thank you in advance if anybody can help in any way, -A -- ---------------------------- Igor Costa www.igorcosta.org <http://www.igorcosta.org> www.igorcosta.com <http://www.igorcosta.com> skype: igorpcosta
