我正在设计一个网页，其中有一个 rich:DataTable 我用来在 Database 中添加新的客户信息。
因此，每次单击“添加新”按钮时，丰富的数据表中应该会出现一个新行，其中包含空白输入文本字段。
问题：即使我单击“添加新”按钮多少次，表格中也只剩下一行。
以下是我的网页代码：
<a4j:outputPanel id="rep" rendered="#{adminBean.currentItem == 'Participant' || adminBean.currentItem == 'Administrator'}">
<rich:panel rendered="#{not empty adminBean.currentItem}" header="Add Customer" id="out">
<h:panelGrid columns="2">
<h:commandButton value="Add New" type="button" style="width: 70px" actionListener="#{adminBean.addCustAction}">
<a4j:ajax render="out"/>
</h:commandButton>
<a4j:commandButton value="Delete" style="margin-left: 10px; width: 70px"></a4j:commandButton>
</h:panelGrid>
<rich:dataScroller for="setcust" style="margin-top: 17px"></rich:dataScroller>
<rich:dataTable id="setcust" value="#{adminBean.customerList}" var="custl" rows="10" style="width: 900px;margin-top: 5px">
<rich:column id="col1">
<f:facet name="header">
<h:outputText value="Customer ID" style="font-size: smaller; font-weight: bolder; "/>
</f:facet>
<h:inputText value="#{custl.Id}"></h:inputText>
</rich:column>
<rich:column id="col2">
<f:facet name="header">
<h:outputText value="First Name" style="font-size: smaller; font-weight: bolder;"/>
</f:facet>
<h:inputText value="#{custl.FirstName}"></h:inputText>
</rich:column>
<rich:column id="col3">
<f:facet name="header">
<h:outputText value="Last Name" style="font-size: smaller; font-weight: bolder;"/>
</f:facet>
<h:inputText value="#{custl.lastName}"></h:inputText>
</rich:column>
<rich:column id="col4">
<f:facet name="header">
<h:outputText value="Phone" style="font-size: smaller; font-weight: bolder;"/>
</f:facet>
<h:inputText value="#{custl.phoneNo}"></h:inputText>
</rich:column>
<rich:column id="col5">
<f:facet name="header">
<h:outputText value="Address" style="font-size: smaller; font-weight: bolder;"/>
</f:facet>
<h:inputText value="#{custl.address}"></h:inputText>
</rich:column>
<rich:column id="col6">
<f:facet name="header">
<h:outputText value="City" style="font-size: smaller; font-weight: bolder;"/>
</f:facet>
<h:inputText value="#{custl.city}"></h:inputText>
</rich:column>
<rich:column id="col7">
<f:facet name="header">
<h:outputText value="Email" style="font-size: smaller; font-weight: bolder;"/>
</f:facet>
<h:inputText value="#{custl.email}"></h:inputText>
</rich:column>
</rich:dataTable>
</rich:panel>
</a4j:outputPanel>
以下是 AdminBean 的代码：
@ManagedBean
@ViewScoped
public class AdminBean {
private String currentType;
private String currentItem;
private List<Customer> customerList = new ArrayList<Customer>();
private List<Account> accountList;
private List optionList;
public List getOptionList() {
optionList = new ArrayList<String>();
if (currentType.equals("Add New User")) {
optionList.add("Participant");
optionList.add("Administrator");
} else if (currentType.equalsIgnoreCase("Manage Balance")) {
optionList.add("Withdrawl");
optionList.add("Deposit");
}
return optionList;
}
public void setOptionList(List optionList) {
this.optionList = optionList;
}
public List<Account> getAccountList() {
return accountList;
}
public void setAccountList(List<Account> accountList) {
this.accountList = accountList;
}
public List<Customer> getCustomerList() {
System.out.println("got list..................");
return customerList;
}
public void setCustomerList(List<Customer> customerList) {
this.customerList = customerList;
}
public String getCurrentItem() {
return currentItem;
}
public void setCurrentItem(String currentItem) {
this.currentItem = currentItem;
}
public String getCurrentType() {
return currentType;
}
public void setCurrentType(String currentType) {
this.currentType = currentType;
}
public void addCustAction(){
System.out.println("kshitij jain.......actionListener"+customerList.size());
Customer cust = new Customer();
customerList.add(cust);
}
}
