[英]Cannot populate datatable from Arraylist in JSF
I am trying to populate a datatable from an arraylist. 我试图从arraylist填充数据表。 After searching how to do it, i found out that i need to set value attribute to an arraylist in the jsf page.
在搜索了如何做之后,我发现我需要在jsf页面中将值属性设置为arraylist。 Here is the related part of my managed bean:
这是我的托管bean的相关部分:
@ManagedBean(name = "customer")
@SessionScoped
public class Customer implements Serializable {
private String identityNumber;
private String password;
private List<Account> accounts;
}
And my datatable definition in jsf page: 我在jsf页面中的数据表定义:
<h:form>
<h:dataTable id="accountsTable" value="#{customer.accounts}"></h:dataTable>
The problem is, it gives an error saying "unknown property: accounts". 问题是,它给出了一个错误,说“未知属性:帐户”。 It can see the identityNumber and password attributes but it cannot find accounts attribute.
它可以看到identityNumber和password属性,但它找不到accounts属性。 Can anyone tell me why and help me fix it?
谁能告诉我为什么并帮我修复它?
Thanks 谢谢
Edit: I solved the error but now the table is not populated. 编辑:我解决了错误,但现在没有填充表格。 Here is the code:
这是代码:
<h:form>
<h:dataTable id="accountsTable" value="#{customer.accounts}" var="account">
<h:column>
<f:facet name="header">Account Number</f:facet>
#{account.accountNumber}
</h:column>
</h:dataTable>
</h:form>
Define getters and setters for your accounts
list. 为您的
accounts
列表定义getter和setter。 As it appears from this error, unknown property: accounts
, accounts
is not available for display. 从此错误中可以看出,
unknown property: accounts
, accounts
无法显示。
public List<Account> getAccounts()
{
return accounts;
}
public void setAccounts(List<Account> accounts)
{
this.accounts = accounts;
}
