Technically you don’t need to have
strongly typed objects in the AS for this to work. However it does appear that
you will be going pretty deep into your object hierarchy and therefore the
compiler may not know the type of objects and that it is safe for it to bind. Your
example that you’ve posted will work I think, but if you had something
like {ModelLocator.userInfo.address.city} you would get a warning about unknown
property address and changes won’t be detected. Now if this data is
coming from a WebService and won’t be modified you could choose to ignore
the warning, but if you want to get rid of the warning you may need to do some
casting: {Object(ModelLocator.userInfo.address).city}. That will tell the
compiler that it’s safe to do its thing when it comes to binding.

If I'm getting objects from a web service and want to use them in
data binding, do I have to re-create them in
ActionScript in order
for their various properties and sub-objects to be
bindable?
Ideally, I'd like to just "use what the
server gives me" and not
rewrite the objects in AS. i.e.:
(in my ModelLocator)
public static var userInfo:Object;
(in my GetUserCommand)
ModelLocator.userInfo = event.result[0];
(In my mxml)
<mx:Label text='{"Welcome,
"+ModelLocator.userInfo.firstname+"
"+ModelLocator.userInfo.lastname}'
/>
Is it possible to get this to work like that? or
will ModelLocator
need to have something like:
public static var userInfo:UserVO;
function ModelLocator()
{
ModelLocator.userInfo =
new UserVO();
}
class com.app.path.UserVO
...
I'd rather avoid having to create all the server
side objects on the
client side; they come from the web service
strongly typed, which is
good enough for me, but does Flex need to have all
of the bindable
properties defined at complie-time for binding to
work?
Thanks,
Sean
