public ManuscriptProgress addManuscriptProgress(ManuscriptProgress manuscriptProgress) {
manuscriptProgress=dao.insert(manuscriptProgress);
dao.fetchLinks(manuscriptProgress, "SubmitUser");
dao.fetchLinks(manuscriptProgress, "submitmanuscript");
return manuscriptProgress;
}```这一段可以，是正常的
下面这段就不行
大神帮忙看卡，实在找不到问题在哪儿啊
public List getManuscriptProgress(int state) {
Criteria cnd =Cnd.cri();
cnd.where().and("SubmitUserid","=",Toolkit.getloginid());
if(state!=-1) {
cnd.where().and("state","=",state);
}
List manuscriptProgresses=dao.query(ManuscriptProgress.class, cnd);

       dao.fetchLinks(ManuscriptProgress.class,"submitmanuscript");
       dao.fetchLinks(ManuscriptProgress.class, "SubmitUser");

    return manuscriptProgresses;
}
