Sorry, it's 'WebControl', not 'Control'.

You don't pass the Action parameter, it is send by the Message class, 
and contains the label of the clicked button.

This is the same problem. Your program is run at each request from 
scratch, so you lose all your global variables. If you want to maintain 
data between request, you must store them in your session.

gb.web.form provides a store in each webform :

MyWebForm["key"] = Value

==> 'Value' is store in the session, and can be retrieved at each request.

If you access a database, you must reopen it and run the SQL again at 
each request.

It's a little brain-f..cking, but there is no magic to hide that!
