我有一个 Web 应用程序，其中第一页是登录页面，一旦我正确登录，就会显示主页。该页面有一个选项卡式菜单，如果我第一次单击其中一个选项卡，主页面会再次刷新，而不是转到请求的页面。这仅发生在第一个 clic 上。其他时候，一切正常。
我用 Firefox、Chrome 和 IE7 给它发短信，这种行为只发生在 IE7上。为什么会这样？错误可能在哪里？因为我不知道我应该在这里复制哪一段代码来澄清我的问题。
PD：我使用过滤器，主页使用 bean 来填充表格。我也试过<redirect/>tag in faces-cofig.xml，它解决了这个问题。但是该页面始终显示登录页面中包含的“无效用户”弹出窗口。最后，我丢弃了它。
更新一些代码
我认为问题不在于主页，因为我将其替换为其他页面并且行为相同...（更新 2）但是使用简单的 html 页面可以正常工作。
登录.xhtml：
<h:form id="login">
<h:outputText value="#{msg['login.user']}"/>
<h:inputText value="#{LogBean.name}" required="true"/>
<h:outputText value="#{msg['login.password']}"/>
<h:inputSecret value="#{LogBean.pass}" required="true"/>
<p:commandButton id="botonAccesoPrim"
value="#{msg['login.enter']}"
action="#{LogBean.checkLog}"
oncomplete="dlg1.show();">
</p:commandButton>
<p:dialog id="popup"
visible="#{LogBean.popup}"
widgetVar="dlg1"
modal="true">
<h:outputText value="Invalid User." />
</p:dialog>
日志豆：
public class LogBean {
private String name;
private String pass;
private String validate = "";
private String popup = "false";
//Getters, setters
public String checkLog() throws Exception {
if (correctLog(md5Final)) {
popup = "false";
validate= "success";
return validate;
}
else {
popup = "true";
validate = "fail";
return validate;
}
}
public boolean correctLog(String md5) throws SQLException {
boolean correct = false;
String sql = "SELECT ...";
String passBBDD = null;
cConexionOracle.conecta();
ResultSet result = OracleConnection.query(sql);
if (!(result.next()))
return correct;
else {
passBBDD = result.getString("pass");
if (md5.equals(passBBDD))
correct = true;
}
OracleConnection.desconect();
return correct;
}
public boolean isLogged () {
return name != null;
}

LogBean BeanConnection = (LogBean) req.getSession().getAttribute("LogBean");

chain.doFilter(req, resp);
return;
