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" style="border-width: 1px;"><div class="codeHeader panelHeader pdl" style="border-bottom-width: 1px;"><b>Index.tml (partial)</b></div><div class="codeContent panelContent pdl">

<t:actionlink t:id="start">start guessing</t:actionlink>
</p>
</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 class="confluence-embedded-file-wrapper confluence-embedded-manual-size"><img class="confluence-embedded-image" width="500" src="implementing-the-hi-lo-guessing-game.data/hilo-index-missing-action-error.png"></span></p><p>Tapestry 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.
