JSF 2. Strange behavior navigating between pages using IE7 - jsf-2

Question

I have a web application where the first page is a login page, and once I am logged correctly, the main page is displayed. The page has a tabbed menu and if the first time I click on one of the tabs, the main page is refreshed again instead of going to the requested page. This occurs only on the first clic. The other times, everything works fine.
I texted it with Firefox, Chrome and IE7, and this behavior only happened with IE7. Why could this be? Where the error could be? Because I don't know what piece of my code should I copy here to clarify my question.
PD: I use a Filter and the main page uses a bean to populate a table. I also tried <redirect/> tag in faces-cofig.xml, and it solved the problem. But the page always showed the "Invalid User" popup contained in the login page. And finally, I discarded it.
Update with some code
I think the problem isn't in the main page, because I replaced it by other pages and the behavior is the same... (Update 2) But with a simple html page it works fine.
login.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:dialog id="popup"
visible="#{LogBean.popup}"

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");

correct = true;

Answer 1

IE7 and jsf 2 will give you various problems. We have not encountered this problem specifically but many others.
Our problems mostly boiled down to tables. JSF is pretty table centric and many components translates to html with one or several tables. For example we commonly had to use some extra css for aligns.
For some tables we had to set the table header width with javascript. Problem was IE7 broke the table because it couldn't determine header width.
Unsure if you can draw any clues from this. But I would advise you to think in terms of workarounds rather than "what's wrong with the code".
