  /**
   * Store the session's current state in a session attribute.
   *
   * <p> To keep track of the state of a user's session, a string is
   * stored in a session attribute in order to allow to chose between
   * different pipelines in the sitemap accordingly.</p>
   *
   * <p> For added flexibility it is possible to use sub states as
   * well. For this declare your own name for the session state
   * attribute and give the number of sublevels plus the level to
   * modify. (This is <b>one</b> based!) Sub states below the current
   * one are removed from the session so that the default sub state will
   * be reentered when the user returns. If you don't like this
   * behaviour and prefer independent sub states, use this action
   * several times with different attribute names rather than sub
   * levels. </p>
   *
   * <p><b>Global and local paramters:</b></p>

   *   <tr>
   *     <td><code>state-key-prefix</code></td>
   *     <td>String that identifies the attribute that stores the session state in the
   *     	 session object. When sublevels are used, this is a prefix ie. the
   *     	 number of the level is appended to the prefix. Example prefix is
   *     	 "<code>__sessionState</code>", sub-levels is 2, attributes
   *     	 "<code>__sessionState1</code>", "<code>__sessionState2</code>",
and
   *     	 "<code>__sessionState3</code>" will be used to store the
   *     	 information.
