} 调用之处：
@RequestMapping("/listAgentAwaitRepor")
public List listAgentAwaitRepor(HttpServletRequest request) throws ServiceException
{
TableTagBean ttb = TableTagBean.getFromParameter(request);
return oldAgentAwaitReportSearchFacade.list(ttb);
} 取值之处：
String titleName = ttb.getCondition().get("titleName");
if(!GenericValidator.isBlankOrNull(titleName))
{
sql.append(" and biz.biz_title like :bizTitle ");
sqlParams.put("bizTitle", "%"+titleName.trim()+"%");
