我有一个下拉列表(id =" localOffInputId"),其值需要根据文本框输入进行修改(id =" rZip")。当表单中没有验证错误时,它可以正常工作。发生验证错误时,表单将按预期重新显示错误消息。现在,当我更改文本框中的值时,将调用侦听器方法(updateLocalOffice())并将localOfficeCode设置为新值,但下拉选择在浏览器中不会更改。我注意到,尽管调用了localOfficeMap的getter,但是在调用ajax之后没有调用localOfficeCode属性的getter。知道为什么只有在验证失败时才会发生这种情况?

找到问题的答案。添加&#34; resetValues =&#34; true&#34;&#34;到ajax调用修复了这个问题
