Hi,

besides the "commmand" for a (e.g.) button which you may 
access via actionEvent.getActionCommand() there are no
parameters.

The "action" attribute always specifies a public field in the object
given to the SwingEngine constructor or in the class SwingEngine is
derived from.

What is your goal? Write a huge actionPerformed() method switching over
the possible parameters it received? Why not write them seperatly as 
Actions in the first place? Or even as standalone classes using initclass?
So you may activate them at your wish and don't need to change the 
code checking your parameters if you do not need a certain business
logic anymore.
