Again, alternative frameworks can use alternative but equivalent
mechanisms for getting the data on the button type pressed.
-
+One last important matter. The buttons are distinguished by what they do, not what
they say. You can have either "GO.gif" or "CLICK.gif" or "SUBMIT.gif" go with
"button.submit" without changing the Action or !ActionForm classes. And, a new
operation will require a change only in the Action class, not in the !ActionForm class.
Enjoy! Namaste!
