The first four Notification.Type
types work for me.
Notification.Type.HUMANIZED_MESSAGE
Notification.Type.TRAY_NOTIFICATION
Notification.Type.WARNING_MESSAGE
Notification.Type.ERROR_MESSAGE
Notification.Type.ASSISTIVE_NOTIFICATION
But the Notification.Type.ASSISTIVE_NOTIFICATION
does nothing for me when running in Safari browser in Mac OS X Mountain Lion.
I cannot find any description of behavior for this particular type in either
the class doc
or in
the Book Of Vaadin
.
