I really think i didnt explain the real problem properly.
i did what u said without any problem. studied all documentation about
fileReference too.
The point is that, IN ANOTHER POINT OF THE CODE, i wanna send the files.
the on_select is not useful for me. i will not send anything on_select, just
put a pair of lines of code there.
But later, user will click the button SEND, and send all the files that he
actually selected (with several browse() actions over several fileReference
objects)
so when user click SEND i should check for all FileReference Objects, and send
ONLY the ones that where actually selected.
So i need a fileReference.selected:boolean function or property, but there is
no function like that. I tried to access to any property from the object, like
.name but it would crash my app if the file was not selected.
so finally, what i need is something like this:
if (myFileReference.selected()=true) { myFileReference.upload() }
i tried this, but crashes when file is not selected:
if (myFileReference.name.length>0) { myFileReference.upload() }
i guess i could create a myFRselected variable for EVERY fileReference i
have...but is not really a nice option :/
thnx

Ok. Then all you need to do is use FileReference instead of FileReferenceList.
There is not much to change in the code.
Any attempt to get the .name property before the select event is dispatched
will result in an IllegalOperationErr or (because you can't even look at name
until Event.SELECT is dispatched).
So, in the onSelectFile method that I posted, .name will then be available - it
will be null if no file was selected. Additionally, check the documentation on
browse(). You might be doing something else funky that is wrong - such as
messing with typelist and not providing descriptions or extension strings.
There are a few things that would cause the browse() not to return true.
The following should work (not tested).
private var isBrowsingFile: Boolean = false;
private function addFiles():void
{
myFileReference = new FileReference( );
if (!isBrowsingFile) {
try
{
isBrowsingFile = myFileReference .browse() ;
myFileReference. addEventListener (Event.SELECT, onSelectFile) ;
}
catch (error:Error)
{
isBrowsingFile = false;
// Handle errors, or add listeners in the try block for errors
// This is where you would get the IllegalOperationErr or
}
}
else
{
trace("already browsing for a file");
}
}
// Called when file is selected
private function onSelectFile( event:Event) :void
{
isBrowsingFile = false;
if (myFileReference. name)
{
// whatever you want to do with the selected file
}
else
{
//no file selected
}
}
good luck with it,
jon
