Javadoc
If the dispatcher is configured to use named event, the return value of
this method is used to identiy a LowLevelEventListener by name. E.g. in a
http request you might give an action a special name, like
"ActivateUpload" to make uploads possible. This action is a SButton in
wings with the name "ActivateUpload" and an ActionListener which make the
upload form visible. A designer might call your servlet with
"servlet/_?ActivateUpload=1" to make the upload form visible by hand. Be
careful, this so called "Named Events" are not under control of wings, so
they will no be outtimed and might lead to strange effects.
