[flexcoders] Don't need to upload file, but need to display it E4X.

[artgrater]

I am trying to let the user browse and select a file that I display but not 
save. 

For interim test purposes, the HTTPService uploads a file if it's name is 
already entered in 
the TextInput control when the btnSelect button is clicked. The XML displays 
properly in 
the taStatus TextArea. 

The problem is that I want to display the XML file that the user browses to, 
not the file 
entered in the TextInput. I have tried binding to the 'name' property of 
FileReference, but 
that doesn't go to the proper folder. 

There's no back-end script because I do NOT need to save the selected file to 
the server. I 
just need to show it and do some other stuff in another component. Or do I need 
a back-
end script just to tell flex where to locate the file that was browsed to?


Thanks!
