    p_code => 'myOwnWidget('||
                  '"#'||p_item.name||'",'||
                  '{'||
                  apex_javascript.add_attribute('ajaxIdentifier',      apex_plugin.get_ajax_identifier)||
                  apex_javascript.add_attribute('dependingOnSelector', apex_plugin_util.page_item_names_to_jquery(p_item.lov_cascade_parent_items))||
                  apex_javascript.add_attribute('optimizeRefresh',     p_item.ajax_optimize_refresh)||
                  apex_javascript.add_attribute('pageItemsToSubmit',   apex_plugin_util.page_item_names_to_jquery(p_item.ajax_items_to_submit))||
                  apex_javascript.add_attribute('nullValue',           p_item.lov_null_value, false, false)||
                  '});' );
