    <p>I'm using JSF 1.2 for developing a small page that requires the user to login. User may have one of three roles, and I should validate if a given user has access to a page given his role.</p> <p>Let's say an admin is the only one that can access the Transactions Report. In the ViewTransactionReportBean default constructor I'm validating this:</p> <pre><code>HttpSession session = (HttpSession)FacesContext.getCurrentInstance().getExternalContext().getSession(false); LoginBean lb = null; try { lb = (LoginBean)session.getAttribute("loginBean"); char role = lb.getRole(); if(role!='A') //Throw an exception to invalidate access }//catch here both invalid user or null pointer (not logged in) exceptions </code></pre> <p>This bean is request scope, so it should load with every Http request I make right?</p> <p>Let's test this scenario: I login as an admin. I click on the View Transaction Report page. I can see the report. I click Home. I click Log out (with logic): </p> <pre><code>public String logOut() {session.invalidate(); return "success";} </code></pre> <p>After I logout (and I'm back to login page), I directly access ../faces/viewTransactionReport.jsp by entering the URL in my browser. Instead of showing an error message, I get to see the whole report, in exactly the last state I left it before I clicked Home (before logout). It is until I refresh the page (F5) that I get the error message saying that I'm not logged in or I don't have permissions.</p> <p>After I tried debugging, when I entered the URL directly in my browser, I noticed that not even the bean constructor was called.</p> <p>But I have no idea why.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
