我通过字段中的操作使用Web服务来检索一些附加数据以及验证用户输入。验证是通过在实例中存储验证状态并使输入字段检查代码不存在有效来完成的。只要我不尝试使用重复的网格，这就可以正常工作。当使用重复网格时，相同的实例用于所有重复的字段。 Web服务数据是独立正确加载的，但验证在所有这些数据之间共享。如何调整代码以便在重复网格中正常工作？

答案 0 :(得分：0)
您使用的是哪种版本的Orbeon Forms？自4.5 control resolution follows repeats in actions起，您服务的结果应该只更改当前迭代的name和address，即userId更改并触发的Set x = Workbooks.Open("C:\Exportbook.xlsx").UpdateLinks = xlUpdateLinksUserSetting
行动，这似乎是你正在寻找的。
