Nhibernate 问题 “path expected for join!”

小弟最近在搞Nhibernate,遇到这样一个问题，比较棘手。
类：
public class Blpsitm
{

public Blpsitm()
{

}

public Blpsitm(string itemcode)
{
this.ItemCode = itemcode;

}

#region 产品信息 Product Information
/// <summary>
/// 产品代码
/// </summary>
public virtual string ItemCode { get; set; }
/// <summary>
/// 注册证号
/// </summary>
public virtual string Registered { get; set; }
/// <summary>
/// 批准文号
/// </summary>
public virtual string Licensedid { get; set; }
/// <summary>
/// 品名
/// </summary>
public virtual string DrugName { get; set; }

#endregion

}

public class CurrentlyInfo
{
public CurrentlyInfo()
{

}

public CurrentlyInfo(string proLotNo)
{
this.ProLotNo = proLotNo;
}

public CurrentlyInfo(string proLotNo,string itemCode)
{
this.ProLotNo = proLotNo;
this.ItemCode = itemCode;
}

#region 打印信息
/// <summary>
/// 批号(除MML类产品,长度为6)
/// </summary>
public virtual string ProLotNo { get; set; }
/// <summary>
/// 产品代码
/// </summary>
public virtual string ItemCode { get; set; }
/// <summary>
/// 批号（原始）
/// </summary>
public virtual string OrgLotNo { get; set; }

#endregion

}

配置文件：
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">
<class name="Blpsitm" table="Blpsitm">
<id name="ItemCode" type="string" length="7" />
<property name="Registered" type="string" length="50" />
<property name="Licensedid" type="string" length="50" />
<property name="DrugName" type="string" length="50" />
</class>
</hibernate-mapping>

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">
<class name="CurrentlyInfo" table="CurrentlyInfo">
<id name="ProLotNo" type="string" length="10" />
<property name="OrgLotNo" type="string" length="50"/>
<many-to-one name="ItemCode" class="Blpsitm" column="ItemCode"></many-to-one>
</class>
</hibernate-mapping>

在执行select c.ProLotNo,c.ItemCode,b.DrugName,b.Quantity from CurrentlyInfo c left join Blpsitm b 是出现如下错误：
Path expected for join!
请问各位大虾，是怎么回事？谢谢
