Salesforce 使用apex代码保存数据后无法清除文件

因为帐户值在视图状态下仍然可用。 在pagereference方法中添加另一行，这应该会有所帮助。大概是这样的：

//Apex Class

public class MyController {


    private Account account; public Account getAccount(){
    if(account == null)
    account=new Account();
    return account;
    }
    public PageReference save(){
    insert account;
    return null;
    }
}

My code is saving the data to my account successfully.But,the fields are not clearing until i press refresh button. 

So, anyone can guide me to clear the page after saving my data?

我看不出有什么问题。但是，您是否尝试使用apex:commandButton的重新渲染器属性？

//Apex Class

public class MyController {


    private Account account; public Account getAccount(){
    if(account == null)
    account=new Account();
    return account;
    }
    public PageReference save(){
    insert account;
    return null;
    }
}

My code is saving the data to my account successfully.But,the fields are not clearing until i press refresh button. 

So, anyone can guide me to clear the page after saving my data?

public PageReference save(){
   insert account;
   account=null;
   return null;
}
