[flexcoders] Re: Return data to FileReference

[Santiago Gonzales]

I think he is referring to the two different types of events that you
can listen for on a FileReference.  

1) Event.COMPLETE which does not have a data property (Event Class)

and 

2) DataEvent.UPLOAD_COMPLETE_DATA which does have the property
(DataEvent Class)

Both are in the docs for file reference.

[flexcoders] Re: Return data to FileReference

[Santiago Gonzales]

Listen for the DataEvent.UPLOAD_COMPLETE_DATA.  The DataEvent has a
data property that does exactly as Tracy described.  I've done the
same thing recently to return XML information back to the application
from the upload servlet.  The XML you return contain whatever
information you want.

private function onUploadComplete(event:DataEvent):void {   
var data:XML = XML(event.data); 
...
...

[flexcoders] Re: Wierd behaviour with selectedItem on Datagrid

[Santiago Gonzales]

I'm also not sure why this happens, but if you change the code in
function cc of dg.selectedItem = array[3] to dg.selectedIndex = 3 it
works.
