Web Dynpro Window 2008-06-12 03:20:45 Definition A window is used to combine several Views and View Sets (the concept of view sets is only offered in Web Dynpro for Java). A view can only be displayed by the browser if it has been embedded in a window. A window always contains one or more views, which are connected by navigation links. One of these views, or a view set, is specified as the start view and is displayed the first time t Read more:Window
Web Dynpro Component Window Plugs 2008-06-12 03:20:16 The concept of the window controller and window plug is not implemented for Web Dynpro Java in SAP NetWeaver 7.0. Inbound Plugs
and Outbound Plugs A window has one or several inbound or outbound plugs. Using these plugs, a window can be included into a navigation chain. The concept of these plugs corresponds to the concept of the plug for a view. Each plug of a window is visible within the entir Read more:Component

Web Dynpro Component Controller 2008-06-12 03:19:38 Definition Controllers are the active parts of a Web Dynpro application. They define how the user can interact with the Web Dynpro application. The data that a controller can access is defined in the corresponding context. Different instances of controllers and contexts exist within a Web Dynpro application. In addition to view controllers, which control the behavior of an individual view, there Read more:Component
Web Dynpro Component Context 2008-06-12 03:19:05 Definition The data used in the component or in the view is stored in the context. Read-write access to this data is available using the controllers as a starting point. Structure The data from the contexts is managed in a hierarchical structure. Each context has a root node, underneath which the individual data fields (attributes) are stored in a tree structure. You create this tree structure Read more:Component

Web Dynpro Component Context Node Properties 2008-06-12 03:18:10 Cardinality of a Context
Node When a node is created in the context of a Web Dynpro component, the cardinality of the node is specified. The cardinality defines how often a node is to be instantiated at runtime – that is, how many elements of this node are available at runtime. Cardinality Cardinality Description 1…1 Only one element is instantiated. 0…1 At runtime, no more th Read more:Component

Web Dynpro Component Event 2008-06-12 03:15:30 The component controller allows you to create events. Events are used to communicate between controllers and enable one controller to trigger event handlers in a different controller. Cross-component communication can be implemented using the interface controller’s events. Events that were created in the component controller are visible within the component only. Inbound Plugs Inbound plug Read more:Component
Web Dynpro Component Action 2008-06-12 03:15:00 Actions for UI Element Events Some UI elements, such as the button element, can react to a user’s interaction: Clicking on the corresponding pushbutton can trigger a handling method to be called within the view controller. Such UI elements are equipped with one or several general events that can be linked with a specific action at design time (switching to a subsequent view, for example). If su Read more:Component

Interfaces of Web Dynpro Components 2008-06-12 03:14:28 Each component has an interface in order to enable communication between Web Dynpro components and to enable a component to be called up by a user. This interface consists of two parts: Interface View of a Window Contained in a Component The interface view of a Web Dynpro window is used to link a window with a Web Dynpro application that can be called by the user. An embedded component can al Read more:Interfaces

Web Dynpro Application 2008-06-12 03:13:56 A Web Dynpro application is an application that can be called from the user interface. As an independent program unit it connects a URL that can be accessed by the user with a window in the Web Dynpro component. The Web Dynpro application is merely linked to an interface view of a Web Dynpro by an inbound plug declared as a startup plug. It therefore contains no information whatsoever about Read more:Application
Web Dynpro Model 2008-06-12 03:13:31 DefinitionWeb Dynpro technology is based on the Model View Controller paradigm, to ensure a clear division between the definition of the user interface and the implementation of the application logic. Within this concept, the model retrieves the application data from the back-end system. If you want to define multiple models, the model must be bound to the relevant Web Dynpro component that the mo

Active Services in SICF Web Dynpro ABAP 2008-06-12 03:11:36 Once you have installed the Application Server ABAP (AS ABAP) all Internet Communication Framework (ICF) services are available in an inactive state for security reasons. After the installation you have to decide which services must be activated for the applications you want to use. Since multiple services can be executed when you call a URL, all service nodes must be activated in the SICF tree. Read more:Active

Fully Qualified Domain Names (FQDN) 2008-06-12 03:10:32 In Web Dynpro ABAP it is imperative that a client browser with a fully qualified domain name (FQDN) has access to the AS-ABAP. For this reason the full URL must be assigned to a Web Dynpro ABAP application when it is called. The URL must not be shortened (for instance, no domain specification). The domain used must also satisfy the requirements of the cookie specification (see ). To check the FQ Read more:Names

Web Dynpro ABAP View 2008-06-12 03:08:34 The view is the smallest unit of a Web Dynpro application visible for the user. The layout elements and dialog elements – for example, Tables, Textfields, or InputFields – required for the application are arranged in a view. The view contains a controller and a controller context in which the application data to be processed is stored in a hierarchical structure. This allows the linking of the
Web Dynpro ABAP UI Elements of the View 2008-06-12 03:08:00 The provided UI elements are used to structure information and functions within the view. This means that they are crucial for the design of the screen layout. Therefore, multiple elements are available with a wide range of purposes: Some elements are used for the graphical arrangement of UI elements like Group or Tabstrip. You can embed other elements into these elements. Elements like Table or
