また、Ajax呼び出しすると下記の例外がスローされるのですが、
原因、状況がわかりましたら、教えていただけないでしょうか。

var page = function() {
        function xxxx_searchAction_ajaxPage(res) {
                Kumu.Ajax.render(res);
        }
        var code = $i('codeInput');
        Kumu.Ajax.executeTeedaAjax(xxxx_searchAction_ajaxPage, [code.value]);
};

SearchActionクラス
----
public Map<String, List<Summary>> ajaxPage(String code)
  throws BusinessException {
	SearchCondition searchCondition
	 = this.searchPage.getSearchCondition();
	searchCondition.setPageNo(this.searchPage.getPageIndex());
	search(searchCondition);
	Map<String, List<Summary>> map = new HashMap<String, List<Summary>>();
	map.put("searchResultItems", this.searchPage.getSearchResultItems());
	return map;
}
