In Wicket the concept of âmodelâ is probably the most important topic of the entire framework and it is strictly related to the usage of its components. In addition, models are also an important element for internationalization, as we will see in paragraph 12.6. However, despite their fundamental role, in Wicket models are not difficult to understand but the best way to learn how they work is to use them with forms. That's why we haven't talked about models so far, and why this chapter discusses these two topics together.
-<h2 id="chapter10_1">10.1 What is a model?</h2>
+<h2 id="chapter10_1">11.1 What is a model?</h2>
<p class="paragraph"/>Model is essentially a <a href="http://en.wikipedia.org/wiki/Facade_pattern" target="blank">facade</a> interface which allows components to access and modify their data without knowing any detail about how they are managed or persisted. Every component has at most one related model, while a model can be shared among different components. In Wicket a model is any implementation of the interface org.apache.wicket.model.IModel:<p class="paragraph"/><img border="0" class="center" src="../img/uml-imodel.png"></img><p class="paragraph"/>The IModel interface defines just the methods needed to get and set a data object (getObject() and setObject()), decoupling components from concrete details about the persistence strategy adopted for data. In addition, the level of indirection introduced by models allows access data object only when it is really needed (for example during the rendering phase) and not earlier when it may not be ready to be used.<p class="paragraph"/>An
y component can get/set its model as well as its data object using the 4 public shortcut methods listed in the class diagram above. The two methods onModelChanged() and onModelChanging() are triggered by Wicket each time a model is modified: the first one is called after the model has been changed, the second one just before the change occurs. In the examples seen so far we have worked with Label component using its constructor which takes as input two string parameters, the component id and the text to display:<p class="paragraph"/><div class="code"><pre>add(<span class="java-keyword">new</span> Label(<span class="java-quote">"helloMessage"</span>, <span class="java-quote">"Hello WicketWorld!"</span>));</pre></div><p class="paragraph"/>This constructor internally builds a model which wraps the second string parameter. That's why we didn't mention label model in the previous examples. Here is the code of this constructor:<p class="paragraph"/><div class="code"><pre><span
class="java-keyword">public</span> Label(<span class="java-keyword">final</span> <span class="java-object">String</span> id, <span class="java-object">String</span> label) {
<span class="java-keyword">this</span>(id, <span class="java-keyword">new</span> Model<<span class="java-object">String</span>>(label));
}</pre></div><p class="paragraph"/>Class org.apache.wicket.model.Model is a basic implementation of IModel. It can wrap any object that implements the interface java.io.Serializable. The reason of this constraint over data object is that this model is stored in the web session, and we know from chapter 6 that data are stored into session using serialization.<p class="paragraph"/><blockquote class="note">

<p class="paragraph"/>One of the main goals of Wicket is to use JavaBeans and POJO as data model, overcoming the impedance mismatch between web technologies and OO paradigm. In order to make this task as easy as possible, Wicket offers two special model classes: org.apache.wicket.model.PropertyModel and org.apache.wicket.model.CompoundPropertyModel. We will see how to use them in the next two examples, using the following JavaBean as the data object:<p class="paragraph"/><div class="code"><pre><span class="java-keyword">public</span> class Person <span class="java-keyword">implements</span> Serializable {<p class="paragraph"/> <span class="java-keyword">private</span> <span class="java-object">String</span> name;

<p class="paragraph"/>Models that implement the interface org.apache.wicket.model.IChainingModel can be used to build a chain of models. These kinds of models are able to recognize whether their model object is itself an implementation of IModel and if so, they will call getObject on the wrapped model and the returned value will be the actual model object. In this way we can combine the action of an arbitrary number of models, making exactly a chain of models. Chaining models allows to combine different data persistence strategies, similarly to what we do with chains of <a href="http://java.sun.com/developer/technicalArticles/Streams/ProgIOStreams" target="blank">I/O streams.</a> To see model chaining in action we will build a page that implements the List/Detail View pattern, where we have a drop-down list of Person objects and a form to display and edit the data of the current selected Person.<p class="paragraph"/>The example page will look like this:<p class="paragraph"/><img bor
der="0" class="center" src="../img/model-chaining.png"></img><p class="paragraph"/>What we want to do in this example is to chain the model of the DropDownChoice (which contains the selected Person) with the model of the Form. In this way the Form will work with the selected Person as backing object. The DropDownChoice component can be configured to automatically update its model each time we change the selected item on the client side. All we have to do is to override method wantOn SelectionChangedNotifications to make it return true. In practice, when this method returns true, DropDownChoice will submit its value every time JavaScript event onChange occurs, and its model will be consequently updated. To leverage this functionality, DropDownChoice doesn't need to be inside a form.<p class="paragraph"/>The following is the resulting markup of the example page:<p class="paragraph"/><div class="code"><pre>…

As we have seen, model chaining allows us to combine the actions of two or more models without creating new custom implementations.

<p class="paragraph"/>In chapter 6 we have seen how Wicket uses serialization to store page instances. When an object is serialized, all its referenced objects are recursively serialized. For a page this means that all its children components, their related models as well as the model objects inside them will be serialized.
For model objects this could be a serious issue for (at least) two main reasons:

<p class="paragraph"/>Sometimes our custom components may need to use more than a single model to work properly. In such a case we must manually detach the additional models used by our components. In order to do this we can overwrite the Component's onDetach method that is called at the end of the current request. The following is the generic code of a component that uses two models:<p class="paragraph"/><div class="code"><pre>/**

Using models we do not only decouple our components from the data source, but we can also relay on them (if they are dynamic) to work with the most up-to-date version of our model object. If we decide to bypass models we lose all these advantages and we force model objects to be serialized.

<p class="paragraph"/>Models are at the core of Wicket and they are the basic ingredient needed to taste the real power of the framework. In this chapter we have seen how to use models to bring data to our components without littering their code with technical details about their persistence strategy.
We have also introduced Wicket forms as complementary topic. With forms and models we are able to bring our applications to life allowing them to interact with users. But what we have seen in this chapter about Wicket forms is just the tip of the iceberg. That's why the next chapter is entirely dedicated to them.
