猜想下：username大小写有没有可能出错了？

package com.tapestry4.engine;
import java.util.List; public class MyVisit { private String username; private List fruitCartList; public List getFruitCartList() { return fruitCartList; } public void setFruitCartList(List fruitCartList) { this.fruitCartList = fruitCartList; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } } 这个是 visit类 大小写应该没有错吧 |

谁看出来是撒错误 给个指导
根据官方 配置seesion级的状态的 那个 <contribution configuration-id="tapestry.state.ApplicationObjects"> <state-object name="visit" scope="session"> <create-instance class="com.tapestry4.engine.MyVisit"/> </state-object> </contribution> 配了还是不行 |

我又回答错了
你要在border.java里面加上 @InjectState("visit") public abstract MyVisit visit ; 记得加上tapestry annotation这个包。 |
