我试图在 AJAX 调用后将选项设置为后端的特定值，但是尽管所有其他字段类型都已成功设置，但 selectOneMenu 没有。我正在使用 Primefaces/JSF。

xhtml:

<p:inputText id="cpr" value="#{customerbean.customer.cpr}">
                <p:ajax event="change" listener="#{customerbean.fetchCustomerDatafromCBS}" update="@form" immediate="true" >
                    <f:param name="cprNumber" value="#{customerbean.customer.cpr}"/>
                </p:ajax>                 
                <f:validator validatorId="cprValidator" />                    
            </p:inputText>   


                <p:selectOneMenu id="gender" value="#{customerbean.customer.gender}" required="#{!customerbean.disabled}" requiredMessage="#{text['validation.error.required.gender']}" disabled="#{customerbean.disabled}">                      
                <f:selectItem itemLabel="Select One" itemValue="" noSelectionOption="true" />  
                <f:selectItem itemLabel="Male" itemValue="Male" />  
                <f:selectItem itemLabel="Female" itemValue="Female"  />  
                </p:selectOneMenu>

豆：

        getCustomer().setGender(fetchedCustomer.getGender().trim());

注意 我刚刚发现该值已设置（因为数据库行插入了正确的值） - 但浏览器上的 selectOneMenu UI 对象并未反映这一点。

好的，我在 f:selectItem 上找到了罪魁祸首：noSelectionOption="true"。一旦我删除它，它就可以正常工作。maritalStatus 起作用的原因是它没有 noSelectionOption 属性。

将 customerbean 设置为@ViewScoped

例如：

@ManagedBean
@ViewScoped
public class customerbean implements Serializable {

}
