-<p>The template listener needs to be registered using the <a href="../../../package/pip/template-listener/">templateListener package installation plugin</a>.
-The corresponding complete <code>templateListener.xml</code> file is included <a href="#templatelistenerxml">below</a>.</p>
-<p>The template code alone is not sufficient because the <code>birthday</code> field is, at the moment, neither read, nor processed, nor saved by any PHP code.
-This can be be achieved, however, by adding event listeners to <code>PersonAddForm</code> and <code>PersonEditForm</code> which allow us to execute further code at specific location of the program.
-Before we take a look at the event listener code, we need to identify exactly which additional steps we need to undertake:</p>
-<ol>
-<li>If a person is edited and the form has not been submitted, the existing birthday of that person needs to be read.</li>
-<li>If a person is added or edited and the form has been submitted, the new birthday value needs to be read.</li>
-<li>If a person is added or edited and the form has been submitted, the new birthday value needs to be validated.</li>
-<li>If a person is added or edited and the new birthday value has been successfully validated, the new birthday value needs to be saved.</li>
-<li>If a person is added and the new birthday value has been successfully saved, the internally stored birthday needs to be reset so that the birthday field is empty when the form is shown again.</li>
-<li>The internally stored birthday value needs to be assigned to the template.</li>
-</ol>
-<p>The following event listeners achieves these requirements:</p>

-<p>Some notes on the code:</p>
-<ul>
-<li>We are inheriting from <code>AbstractEventListener</code>, instead of just implementing the <code>IParameterizedEventListener</code> interface.
-  The <code>execute()</code> method of <code>AbstractEventListener</code> contains a dispatcher that automatically calls methods called <code>on</code> followed by the event name with the first character uppercased, passing the event object and the <code>$parameters</code> array.
-  This simple pattern results in the event <code>foo</code> being forwarded to the method <code>onFoo($eventObj, $parameters)</code>.</li>
-<li>The <code>birthday</code> column has a default value of <code>0000-00-00</code>, which we interpret as “birthday not set”.
-  To show an empty input field in this case, we empty the <code>birthday</code> property after reading such a value in <code>readData()</code>.</li>
-<li>The validation of the date is, as mentioned before, very basic and just checks the form of the string and uses PHP’s <a href="https://secure.php.net/manual/en/function.checkdate.php">checkdate</a> function to validate the components.</li>
-<li>The <code>save</code> needs to make sure that the passed date is actually a valid date and set it to <code>0000-00-00</code> if no birthday is given.
-  To actually save the birthday in the database, we do not directly manipulate the database but can add an additional field to the data array passed to <code>PersonAction::create()</code> via <code>AbstractForm::$additionalFields</code>.
-  As the <code>save</code> event is the last event fired before the actual save process happens, this is the perfect event to set this array element.</li>
-</ul>
-<p>The event listeners are installed using the <code>eventListener.xml</code> file shown <a href="#eventlistenerxml">below</a>.</p>

+<p>As <code>BirthdayPersonAddFormListener</code> extends <code>AbstractEventListener</code> and as the name of relevant event is <code>createForm</code>, <code>AbstractEventListener</code> internally automatically calls <code>onCreateForm()</code> with the event object as the parameter.
+It is important to set <code>&lt;inherit&gt;1&lt;/inherit&gt;</code> so that the event listener is also executed for <code>PersonEditForm</code>, which extends <code>PersonAddForm</code>.</p>
