Interesting... maybe the alert box is getting the key press event,
which isn't being fired until after the alert has popped up because
that's happening on key down. Maybe using
event.getNativeEvent().getKeyCode() in a KeyPressHandler will work.
I'm not sure because I haven't run into this case myself.
The workaround link that David Chandler posted is to issue #5558 in
the GWT issue tracker:
http://code.google.com/p/google-web-toolkit/issues/detail?id=5558
In particular, Thomas Broyer posted what looks like some nice code for
reliably detecting the enter key:
