An obvious enhancement for this dialog would be to make one that accepts an input value and then sends this value back to the launch page To enable this case, we can build a dialog that allows the user to enter a value into a text field in the dialog and then have it appear in a text field on the main page (homejsp) As before, we can add another command component to the home page to launch the dialog This time we ll use a commandButton, as shown next:

The new button s action is set to a dialog navigation case (not shown) that directs the user to a different dialog page (lookupjsp) which accepts a value The new Lookup dialog is shown hovering above the main (Home) page in Figure B-5 We ll continue reviewing the remainder of launch button s attributes shortly, but first let s have a look at the lookupjsp dialog page s most important components:

As you can see, this dialog contains an input field that allows the user to enter a value along with a button that is bound to an action method returnAction( ) in the page s backing bean The source for this method is as follows:

Using Barcode generation for Microsoft Excel Control to generate, create ANSI/AIM Code 128 image in Excel applications.
public String returnAction(){ AdfFacesContextgetCurrentInstance()returnFromDialog(inputText1getValue() , null); return null; }
As shown here, this method calls the ADF Faces context method, returnFromDialog( ), which closes down the dialog and sends back a value in the first argument In this example, the value of the input text field (inputText1) is passed back In order for the value sent back from the dialog to be processed, a corresponding returnListener must be used Recall from the button of the launch page where a handleReturn( ) method was referred to in the button s returnListener attribute, as shown next:
returnListener="#{backing_homehandleReturn}"
The handleReturn( ) method is a method in the backing bean of the launch page that processes the incoming value from the dialog It is shown next:
public void handleReturn(ReturnEvent event) { if (eventgetReturnValue() != null){ outputText1setValue(eventgetReturnValue()); } }

FIGURE B-5
A dialog that accepts an input value
As you can see, it sets the output text field on the launch page to the value returned from the ReturnEvent When the dialog finishes, the original launch page must be refreshed in order to show the new value returned from the dialog This is done by setting the partialSubmit attribute of the original launch button to true as well as setting the partialTriggers attribute of the text field being updated to the ID of the launch button
<af:outputText id="outputText1" partialTriggers="lookup_button"/>
Recalling the PPR discussion, the partialTriggers attribute establishes a dependency from the output text field to the launch button and forces a partial refresh to update the output field Figure B-6 shows the update value of the output text field

ADF Faces Skinning Technology
With ADF Faces skinning technology, developers can create applicationwide look and feels, which govern the overall user interface appearance of the application Other Web technologies have similar features and are sometimes referred to as themes The default look and feel, or skin, that is presented with the ADF Faces components is known as the Oracle look and feel This look and feel was originally created for Oracle applications and is shown in Figure B-7 To quickly change this look and feel to another built-in look and feel simply requires a quick edit of the /WEB-INF/adf-faces-configxml file In addition to the built-in oracle look and feel, there are also two other built-in look and feels, simple and minimal, which can then be extended upon To switch to the minimal look and feel, you must edit the adffaces-configxml and replace the default oracle skin-family with minimal, as shown next:
