当我将一个xml转换为另一个xml并在列表元素中进行映射列表时。我得到一个例外。
＆＃34;不能将a：string强制转换为：object（com.mulesoft.weave.mule.exception.WeaveExecutionException）。消息有效负载的类型为：WeaveMessageProcessor $ WeaveOutputHandler＆＃34;

实际上发生了什么，输出xml的ZIDD0735_KNA1_DETAILS节点下的字段映射到ZCOM_AGR_SOLD下的字段，ZCOM_AGR_SOLD是数据列表，或者你可以说array.In输出我有ZCOM_AGR_SOLD的值，我在ZIDD0735_KNA1_DETAILS下获取数据，但不是ZIDD0735_KNA1_DETAILS的重复值，而是在ZIDD0735_KNA1_DETAILS下获得ZCOM_AGR_SOLD，所有输入xml节点名称都不输出节点名称。仅在此字段中发生这种情况。休息一切正常。

可能是您的日期是造成例外的日期吗？
