Oracle ADF 在输入文本上按 Enter 键创建新行

Question

当我在 InputText 字段中按回车键时，我想创建新行来插入数据。我试图通过使用 Javascript 检查是否按下了输入键并将客户端和服务器侦听器设置为输入字段来实现这一点，但似乎不起作用。谁能帮助我我哪里出错了？ 我的 JSFF 页面：

</af:table>

我在backing bean中的方法：

  public void handleEnterEvent(ClientEvent ce) {

  ViewObject vo = this.getTransMstView1();
  vo.executeEmptyRowSet();
  Row row = vo.createRow();
  vo.insertRow(row);
  vo.setCurrentRow(row);

  }

有一个更简单的解决方案，那就是使用af:subform，它有一个名为defaultCommand的属性，它映射到一个按钮，当你在输入文本上按下回车时，这个按钮将被执行！
