当我在HTML表格中添加新记录时,单击“保存新发票”时,它将显示在transactionTable中。
它第一次正常工作,但当我单击单选按钮并选择支票选项“不显示新数据”和“替换旧数据”时。您不应该在getter/setters中执行业务逻辑 普通的getter/setter对看起来与IDE自动生成的平均值完全相同:
public List<Transaction> getTransactions() {
return transactions;
}
public void setTransactions(List<Transaction> transactions) {
this.transactions = transactions;
}
为了在编辑后保存/更新数据,只需使用actionlistener方法
另见:
谢谢,但我有一个错误,在托管bean Invoicean上执行资源注入时出错。现在怎么解决呢?显然,交易或发票为空,或者get0不存在。只要检查堆栈跟踪的根本原因就可以找到线索,这应该是一个非常基本的非JSF问题。我不能再多说了,因为你没有展示代码的那一部分。但这一部分并不相关。你至少应该确保你不去碰那些能手/二传手。然后解决了当前问题中所述的具体问题。
public List<Transaction> getTransactions() {
return transactions;
}
public void setTransactions(List<Transaction> transactions) {
this.transactions = transactions;
}
@PostConstruct
public void init() {
transactions = transactionDao.getTransactions(invoices.get(0).getId());
}
