You try and guess the number, clicking links. At the end, the computer tells
you how many guesses you required to identify the target number. Even a simple
example like this will demonstrate several important concepts in
Tapestry:</p><ul><li>Breaking an application into individual
pages</li><li>Transferring information from one page to
another</li><li>Responding to user interactions</li><li>Storing client
information in the server-side session</li></ul><p>We'll build this little

sisting of three pages: Index (the starting page), Guess and GameOver. The
Index page introduces the application and includes a link to start guessing.
The Guess page presents the user with ten links, plus feedback such as "too
low" or "too high". The GameOver page tells the user how many guesses they took
before finding the target number.</p><h1

clicking the link doesn't do anything yet, as its just a placeholder <a>
tag, not an actual Tapestry component. Let's think about what should happen
when the user clicks that link:</p><ul><li>A random target number between 1 and
10 should be selected</li><li>The number of guesses taken should be reset to
0</li><li>The user should be sent to the Guess page to make a
guess</li></ul><p>Our first step is to find out when the user clicks that
"start guessing" link. In a typical web application framework, we might start
thinking about URLs and handlers and maybe some sort of XML configuration file.
But this is Tapestry, so we're going to work with components and methods on our
classes.</p><p>First, the component. We want to perform an action (selecting t
he number) before continuing on to the Guess page. The ActionLink component is
just what we need; it creates a link with a URL that will trigger an action
event in our code ... but that's getting ahead of ourselves. First up, convert
the <a> tag to an ActionLink component:</p><div class="code panel pdl"

</pre>
</div></div><p>If you refresh the browser and hover your mouse over the "start
guessing" link, you'll see that its URL is now /tutorial1/index.start, which
identifies the name of the page ("index") and the id of the component
("start").</p><p>If you click the link now, you'll get an error:</p><p><span

is telling us that we need to provide some kind of event handler for that
event. What does that look like?</p><p>An event handler is a method of the Java
class with a special name. The name is
<code>on</code><strong><em>Eventname</em></strong><code>From</code><strong><em>Component-id</em></strong>
... here we want a method named <code>onActionFromStart()</code>. How do we
know that "action" is the right event name? Because that's what ActionLink
does, that's
why its named <strong><em>Action</em></strong>Link.</p><p>Once again, Tapestry
gives us options; if you don't like naming conventions, there's an @<a
class="external-link"
href="http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/annotations/OnEvent.html";>OnEvent</a>
annotation you can place on the method instead, which restores the freedom to
name the method as you like. Details about this approach are in the <a
href="user-guide.html">Tapestry Users' Guide</a>. We'll be sticking with the
naming convention approach for the tutorial.</p><p>When handling a component
event request (the kind of request triggered by the ActionLink component's
URL), Tapestry will find the component and trigger a component event on it.
This is the callback our server-side code needs to figure out what the user is
doing on the client side. Let's start with an empty event handler:</p><div

performs a redirect after each component event. So the first request was to

noted above, Tapestry sends a redirect to the client after handling the event
request. That means that the rendering of the page happens in an entirely new
request. Meanwhile, at the end of each request, Tapestry wipes out the value in
each instance variable. So that means that tar
get <em>was</em> a non-zero number during the component event request ... but
by the time the new page render request comes up from the web browser to render
the Guess page, the value of the target field has reverted back to its default,
zero.</p><p>The solution here is to mark which fields have values that should
persist from one request to the next (and next, and next ...). That's what the

selecting the correct value later.</p><p>When building Tapestry pages, you
sometimes start with the Java code and build the template to match, and
