Im trying to have the option set to a specific value from the backend after an AJAX-call, however although all other field-types are successfully set the selectOneMenu is not. Im using Primefaces/JSF.
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不是。我使用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>
bean:
getCustomer().setGender(fetchedCustomer.getGender().trim());
NOTE I just discovered that the value IS set (because the database row is inserted with the correct value) - but the selectOneMenu UI object on the browser does not reflect that.
注意我刚刚发现值已设置(因为数据库行插入的值正确) - 但浏览器上的selectOneMenu UI对象没有反映出来。

Set customerbean to @ViewScoped
将customerbean设置为@ViewScoped
eg:
@ManagedBean
@ViewScoped
public class customerbean implements Serializable {
}

Ok, I found the culprit: noSelectionOption="true" on the f:selectItem. Once I remove that, it works fine. The reason maritalStatus worked is because it doesnt have the noSelectionOption attribute.
好的,我找到了罪魁祸首:f:selectItem上的noSelectionOption =“true”。一旦我删除它,它工作正常。 maritalStatus工作的原因是因为它没有noSelectionOption属性。
