This simple task is really very confusing :-(
I have been through tutorials, references with comboboxes and Arrays and
this really appears very simple there. However when it comes to remoteobject
it gets extremenly complicated :-(
My guess is.. is there any easy way to convert my ArrayCollection that comes
from the RemoteObject into an array which has no problems at all with the
combobox?
i.e. in order to use this dataprovider in a combobox is very easy!
[Bindable]
public var cards: Array = [ {label:"Visa", data:1},
{label:"MasterCard", data:2}, {label:"American Express",
data:3} ];
[Bindable]
public var selectedItem:Object;
Can I get a remoteobject return me some date and using some simple AS3 to
convert what comes back from my service into this?
thanks,
George
ps: sorry if this sounds like a dump idea - i m not really experianced Flex
Developer at all, just started it :-)
