/**
 * This file contains a list of all ajax handlers for dynamic list item
 * features.
 * Two functions must be defined for each dynamic list item feature:
 *   onSuccess:
 *     This function will be called, if the AJAX request succeeds
 *     (this means, if no network error occurs and the returnCode was
 *      set to 'ok'.)
 *   onError:
 *     This function will be called, if anything prevents the received
 *     return code from being 'ok'.
 *
 *  The signature for each of these functions is (returnCode, htmlCode, itemId)
 *  where
 *    returnCode : The returnCode received from the server. 'ok' will be
 *                 recognized as success.
 *    htmlCode : The messages snippet as pure HTML
 *    itemId : The id of the item, which this AJAX call belongs to.
