ZK's annotated data binding mechanism involves the following players to make it work:

−
* Data Bean

* ZK UI Components declared in ZUL file

* ZK's annotated data binding manager utility

In a nutshell, a bean's particular property is associated with a specified component attribute, such that whenever a value is modified, the annotated data binding manager calls the data bean's getter and setter methods to keep the values in sync between the bean and the component. <br>

In the last section Displaying Information Using Grid, we devised a renderer to associate the View (Product View Grid) with a data model. In this section, we'll look into how we could automate that process with ZK's annotated data binding mechanism.
