NOTe You should see two new files created in the ViewController project when you drag and drop from the Data Controls panel. There is a file <PageName>PageDef.xml for each JSF page. This defines the bindings for each page and is the file you are viewing when you select the Bindings tab as shown in Figure 11-4. There is also a file DataBindings.cpx, which holds information about which JSF page is mapped to which PageDef. You now want to create a binding to be able to show the currently selected customer s e-mail address in the tab of the tabbed panel. To create a new binding, click the green plus sign in Bindings. In the Insert Item dialog, select Generic Bindings, select attributeValues, and click OK.

NOTe Because the tree binding and the attribute value binding are referencing the same data control through the same executable, the CustEmail binding will correctly reference the currently selected data object. The executable is maintaining the pointer to the current row. The final step is to reference that binding from the tabbed panel using Expression Language. This is explained in more detail in the next section, but if you wish to try this now, set the Text property of the showDetailItem subcomponent of the tabbed panel to #{bindings.CustEmail. inputValue}. You can now test that selecting a row in the table displays the e-mail address for the customer in the tab title.

NOTe In order for the text in the tabbed panel to be refreshed, an action has to happen on the page, such as switching tabs. However, if you want to force the refresh automatically, select the CustEmail binding and set its ChangeEventPolicy property to ppr. This is a feature called partial page refresh, which is covered later in the book. This will force the component that references the binding to automatically refresh when the binding has been updated.
understanding expression Language
Expression Language (EL) is a feature of the View technology, that enables you to use an expression to reference Java objects. This is particularly important for ADF Model because EL is used in the properties of the UI component to reference the binding objects created by ADF Model.
using eL to reference Bindings
For any UI component created by dragging and dropping from the Data Controls panel, JDeveloper not only creates the binding, but also references that binding from the appropriate properties of the component. For example, an attribute value binding would be referenced from a text field component s Value property using an expression such as #{bindings.CustomerId. inputValue}. This indicates that the value for the UI component should be derived from the bindings object that ADF Model provides for the page; this is the reference to bindings in EL. CustomerId references the name of the actual binding, and inputValue references the property that should be returned from the binding. However, bindings can return more than just data values. The Label property for a text field could be set to #{bindings.CustomerId.hints.label}. This defines that Label gets its value from the CustomerId binding in the bindings object and returns the label of a control hint. In 5 you learned that you can set up control hints in an entity object or view object; it is these control hints that are being referenced, through ADF Model, by the UI components. And, being an expression language, EL can use operators. An example is setting the Disabled property, which controls whether the button is enabled or disabled, to #{!bindings.Next. enabled}. Note the exclamation mark, which negates the expression and thus sets the Disabled property to false if you are able to navigate to the next row.
