Question

我有这种奇怪的情况，第一次访问包含此代码的页面时，每当我选择任何值时，控件都会从所选值闪烁并返回第一个值 - 如果存在则不调用Listener。从那时起，事情就可以了。

值是字母a-z加上空的非空字符串。

将它与tomcat 7一起使用

bean摘录

public List<String> getLetras() {
        List<String> ls = new ArrayList<String>();
        ls.add("");
        for (int i = 65; i <= 90; i++) {
            ls.add(new String("" + (char)i));
        }
        return ls;
    }

p：selectOneMenu在第一次使用时“拒绝”选择
