顶部链接代码不会更新所有字段

Question

Struts操作类中有以下代码：

        clerkReviewDao.transaction(clerkReviewCaseRecipient,
                    new TransactionBlock<ClerkReviewCaseRecipient>() {
                        public void merge(
                                ClerkReviewCaseRecipient detached,
                                ClerkReviewCaseRecipient managed) {
                            managed.setNotify("Y");
                            managed.setSysDttm(new Date());
                            managed.setSysPIN(HttpDBSessionMgr.getSessionInfo(request).getUserPin());
                        }
                    });

上面的代码调用我们的BaseDAO类（使用Toplink）

import oracle.toplink.publicinterface.Session;
import oracle.toplink.publicinterface.UnitOfWork;
    public T transaction(T detached, TransactionBlock transactionBlock) throws BadDBConnection {
        Session session = centralSourceInjector.inject();
        UnitOfWork uow = session.acquireUnitOfWork();
        try {
            T managed = (T)uow.registerObject((T) detached);
            transactionBlock.merge(detached, managed);
            uow.commit();
            session.refreshObject(detached);
            return managed;
        } catch(OptimisticLockException ole){
            uow.rollbackTransaction();
            throw ole;
        } finally {
            uow.release();
        }
    }

代码只更新Notify列，sysDttm和SysPin列根本不会更新。这是两个变量及其方法。

private Date sysDttm;
private String sysPIN;
public Date getSysDttm() {
    return sysDttm;
}
public void setSysDttm(Date sysDttm) {
    this.sysDttm = sysDttm;
}
public String getSysPIN() {
    return sysPIN;
}
public void setSysPIN(String sysPIN) {
    this.sysPIN = sysPIN;
}

有什么建议吗？

谢谢，

Tom

这个问题与xml文件ClerkReviewCaseDocRecipient.ClassDescriptor.xml中的描述符有关。我没有为sys_dttm和sys_pin列设置正确的链接。我在查看TopLink WorkBench中的配置时发现了这一点。我感谢大家的帮助和建议。
