ByteArray.readUTFBytes() and TextInput.text

Question

Hi all,
I'm working on an Adobe AIR program that allows users to store a username/password in the encrypted local store. Upon application launch, if a stored username/password exists, I want to populate the corresponding username/password text inputs (so the user only has to click the "Login" button). In order to do this, I must get the username/password from the encrypted locat store as ByteArray objects, then call readUTFBytes() to get them into String form.
This is where something very peculiar is happening (perhaps a bug in Flex). If I try to set the text input's text value directly equal to the readUTFBytes() call, the text input remains empty:
var usernameByteArray:ByteArray = EncryptedLocalStore.getItem('some-username');
usernameInput.text = usernameByteArray.readUTFBytes(usernameByteArray.bytesAvailable);
However, if I create a separate string and set that equal to the readUTFBytes() call, then set the text input's text value equal to this new string, then the text input has the desired string:
var usernameByteArray:ByteArray = EncryptedLocalStore.getItem('some-username');
var storedUsername:String = usernameByteArray.readUTFBytes(usernameByteArray.bytesAvailable);
usernameInput.text = storedUsername;
What the hell?

hi
i guess that its a casting issue (ie: it doesnt know that usernameByteArray.readUTFBytes(usernameByteArray.bytesAvailable) is meant to be a String)
your solution is correct, but it can be shortened to one line by casting directly as a String.
change this:
var storedUsername:String = usernameByteArray.readUTFBytes(usernameByteArray.bytesAvailable);
usernameInput.text = storedUsername;
to this:
usernameInput.text = String(usernameByteArray.readUTFBytes(usernameByteArray.bytesAvailable));
