  -      You may even pass literal strings using single or double quotes:
  +       <emphasis>Note:</emphasis> You can not pass objects as arguments! All that is passed is names, for example,
  +       <literal>hotel.id</literal> and <literal>user.username</literal>. If you check the rendered code of the
  +       previous example, you will see that the command button contains these names. These name arguments will be
  +       submitted to the server when you press the button, and Seam will look up and resolve these names (in any
  +       available context) before the action method is called. If the arguments can not be resolved at that time
  +       (because <literal>hotel</literal> and <literal>user</literal> variables can not be found in any available
  +       context) the action method will be called with <literal>null</literal> arguments!
