Binding error

Question

I have a bindable XML variable "Store" and am binding to an
element in mxml using {Store.Address}
All works as expected, but I'm getting a warning :
"Data binding will not be able to detect changes to XMLList
Address, need an XML instance".
Is there a different way to bind to XML elements, or a way to
make the elements bindable?
Thanks!

No, you are fine. I just wanted to remind you that e4x
expressions always return an XMLList.
Actually, the XML function in the above is not really
necessary. You could do:
GLInfo = e.result.Stores.Store.(Code == "GL")[0]; //but
without the array index, this would give a datatype compile error.
I typically have an instance level XML variable to hold the
whole shebang. I also have [Bindable]XMLListCollection variables to
hold commonly used node lists. I populate all those variables in a
result handler function. (Remember to use *new*
XMLListCollection(XMLList))
If you are not going to be updating the items of a
dataProvider individually on the client, then XMLList is ok for a
dataProvider. It is just that the XMLList API methods do not
dispatch the events necessary to automatically sync the UI. But I
habitually wrap XMLList in and XMLListCollection. There is no
reason not to (Flex does it internally if you do not).
