我有一個用戶列表頁面，其中包含p:dataTable中的用戶並且在每一行中我有一個更新按鈕顯示一個p:dialog彈出窗口。 頁面，在對話框中的視圖範圍內（在Spring中實現）進行管理。p：pickList按下後沒有取數據p：commandButton
當我按下editUserButton在主要頁面的彈出窗口的所有數據，然後我鍵入一個無效的字符串到田間電子郵件和用戶名。出現驗證消息，但選項列表中沒有填充任何值。
可能是什麼問題？
這是最主要的頁面（用戶列表）代碼片段：
<ui:composition>
<f:view id="bodyView">
<div id="content_body">
<ui:include src="editUserDialog.xhtml"/>
<h:form id="usersListForm">
<table width="85%" align="center">
<tr>
<td>
<p:dataTable id="usersList" var="user"
value="#{usersController.usersList}"
selectionMode="single"
rowKey="#{user.userId}">
<p:columnGroup type="header">
<p:row>
...
<p:column rowspan="2" headerText="Users"/>
...
</p:row>
</p:columnGroup>
...
<p:column id="users" >
<p:commandLink id="editUserButton" oncomplete="addEditUserConfirmation.show()" actionListener="#{addEditUserController.selectionListener}"
update=":addEditCustomerDialogForm:dialogContent">
<f:attribute value="#{user}" name="selectedUser" />
</p:commandLink>
</p:column>
</p:dataTable>
</td>
</tr>
</table>
<br/>
</h:form>
</div>
</f:view>
這是號碼：對話框代碼：
<ui:composition>
<h:form id="addEditUserDialogForm">
<p:dialog id="addEditUserDialog" severity="alert" widgetVar="addEditUserConfirmation" draggable="true" modal="true"
resizable="false" >
<p:outputPanel id="dialogContent">
<div>
<table cellpadding="5">
<tr>
<td>
<p:inputText value="#{addEditUserController.addEditCustomerBean.userName}"
maxlength="250" size="50" label="user name" id="userName">
<f:validator validatorId="UsernameValidator"/>
</p:inputText>
<p:message for="userName"/>
</td>
</tr>
<tr>
<td>
<p:inputText value="#{addEditUserController.addEditCustomerBean.email}"
maxlength="50" size="50" label="E-mail" id="email">
<f:validator validatorId="EmailValidator"/>
</p:inputText>
<p:message for="email"/>
</td>
</tr>
</table>
<table cellpadding="5">
<tr>
<td>
<p:pickList id="customersList" iconOnly="true"
value="#{addEditUserController.customersList}" var="customer"
itemValue="#{customer.value}" itemLabel="#{customer.label}"/>
</td>
</tr>
</table>
</div>
<div align="right">
<p:commandButton value="#{isNewUser ? 'add' : 'update'}" id="updateUserButton"
actionListener="#{addEditUserController.persistUser}"
update="dialogContent"
styleClass="fiftyone-default-button"
oncomplete="handleRequest(xhr, status, args)"/>
</div>
</p:outputPanel>
</p:dialog>
</h:form>
<script type="text/javascript">
function handleRequest(xhr, status, args) {
if(!(args.validationFailed && args.validationFailed == true)) {
addEditUserConfirmation.hide();
}
}
</script>
這是支持bean代碼：
import org.primefaces.model.DualListModel;
import javax.annotation.PostConstruct;
import javax.faces.event.ActionEvent;
import java.util.List;
public class AddEditUserController {
private AddEditCustomerBean addEditCustomerBean;
private DualListModel<LabelValueBean> customersList;
// ... constructor getters and setters
public void selectionListener(ActionEvent event) throws Exception {
selectedUser = event.getComponent().getAttributes().get("selectedUser");
// some code
AddEditCustomerBean = new AddEditCustomerBean();
// some code
customersList = getSomeCustomersDualListModel()
}
public void persistUser() throws Exception {
// save user to DB
}
}
