    <p>I have a very simple page that is displaying canned data. I experienced this problem with data from a DB so I made this simple example and still have the issue. When this page is navigated to for the first time for a session, the first column in the first row shows no data.</p> <p>It doesn't matter if I change the scope to request or session, nor does it make a difference if I use firefox or IE. All I know is that if I reload the page or navigate away and come back it will all of a sudden show my data - until I close all instances of that browser and load up a new one. Then, again, it won't show my data until I reload the page.</p> <p>The question is why does my beloved first title of my first book never show up until i reload the page ("Operating System Concepts" doesn't show, but "Silberschatz" does)?</p> <p>Below is the relevant code.</p> <p>HomePage.java:</p> <pre><code>public class HomePage { private Book[] books; public HomePage() { books = new Book[3]; books[0] = new Book("Operating System Concepts", "Silberschatz"); books[1] = new Book("Learning Sql", "Beaulieu"); books[2] = new Book("Effective Java", "Bloch"); } public Book[] getBooks() { return books; } public void setBooks(Book[] books) { this.books = books; } } </code></pre> <p>Book.java</p> <pre><code>public class Book { private String title; private String author; public Book() {} public Book(String title, String author) { this.title = title; this.author = author; } public String getTitle() { return title; } public void setTitle(String title) { this.title = title; } public String getAuthor() { return author; } public void setAuthor(String author) { this.author = author; } } </code></pre> <p>home.jsp:</p> <pre><code>&lt;html&gt; &lt;%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %&gt;

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
