Question

我有一个基本的应用程序，我从数据库中获取Loan Products列表并向用户显示。我写了一个xsl转换文件，我在其中迭代结果集并将每一行添加为贷款产品。但最终的List中填充了相同的对象。

我的composite.xml：

GetLoanProductsBPEL内容：

GetLoanProductsBPEL组件内的Transform1文件内容：

在数据库中，我有3个贷款产品：

但结果我获得了同一贷款产品的3个实例：

<env:Body>
    <inp1:GetLoanProductsResponse xmlns:inp1="http://xmlns.oracle.com/singleString">
        <inp1:LoanProduct>
            <inp1:Id>1</inp1:Id>
            <inp1:Name>Cash loan</inp1:Name>
            <inp1:MaxAmount>100000</inp1:MaxAmount>
            <inp1:InterestRate>12</inp1:InterestRate>
            <inp1:MaxPeriod>60</inp1:MaxPeriod>
        </inp1:LoanProduct>
        <inp1:LoanProduct>
            <inp1:Id>1</inp1:Id>
            <inp1:Name>Cash loan</inp1:Name>
            <inp1:MaxAmount>100000</inp1:MaxAmount>
            <inp1:InterestRate>12</inp1:InterestRate>
            <inp1:MaxPeriod>60</inp1:MaxPeriod>
        </inp1:LoanProduct>
        <inp1:LoanProduct>
            <inp1:Id>1</inp1:Id>
            <inp1:Name>Cash loan</inp1:Name>
            <inp1:MaxAmount>100000</inp1:MaxAmount>
            <inp1:InterestRate>12</inp1:InterestRate>
            <inp1:MaxPeriod>60</inp1:MaxPeriod>
        </inp1:LoanProduct>
    </inp1:GetLoanProductsResponse>
</env:Body>

当我查看Flow Trace时，我看到Invoke里面有3个不同的记录，但是在Transform1之后，同样的记录写了3次。

Invoke1追踪：

转换后的ReplyOutput：

快速回答，因为我是从手机上回复的。删除/顶部：VMbLoanProductsCollection / top：VMbLoanProducts /来自for-each循环中的select属性。
