Defining the Navigation Structure 

You can easily create the navigation structure within the form example application, because you must only define two navigation links between the two views Form and EMailEditor and the corresponding inbound plugs and outbound plugs.

Inbound Plugs and Outbound Plugs

Declare two inbound plugs in the views Form and EMailEditor.

Inbound plugs
View	Name	Parameter Name	Parameter Type
Form	DisplayFormIn
EMailEditor	DisplayEditorIn	eMailAddress	string

 

These are the corresponding outbound plugs:

Outbound plugs
View	Name	Parameter Name	Parameter Type
Form	SendEMailOut	eMailAddress	string
EMailEditor	FinishOut

Note that the eMailAddress parameter is declared in the SendEMailOut outbound plug of the Form view controller and in the DisplayEditorIninbound plug of the EMailEditor view controller. This enables you to provide the e-mail address without context mapping.

Make sure that the parameters declared in the inbound plug and outbound plug have identical types and names.

Navigation Links

To define a navigation link from view A to view B, you must assign an inbound plug in view B to an outbound plug of view A.

Navigation Links
Start View	Outbound Plug	Target View	Inbound Plug
Form	SendEMailOut	EMailEditor	DisplayEditorIn
EMailEditor	FinishOut	Form	DisplayFormIn

To create a navigation link in the Web Dynpro Explorer, select the entry  Create Navigation Link in the context menu of an outbound plug.

The declarative part of the view development is now almost completed. The declaration of the methods required for the input checks in the controller of the Form view is described under Implementing the Controller of the Form View.

  The next step is to define messages in the Message Editor of the Web Dynpro component SimpleErrors.
