Eventing Example Application 

The eventing application is meant to reflect a simple application scenario containing two Web Dynpro components. It focuses on the data transfer across Web Dynpro component borders using server-side eventing.

First of all, a Control Panel view appears on the UI, which is part of the embedding Web Dynpro component. In this view, the user can create or delete the embedded Web Dynpro component. In addition, it displays the parameter value received by the event of the inner component.

After creating the inner Web Dynpro component, its view appears on the UI. The user can enter a parameter value there and trigger the associated event. Then the parameter value is displayed in the upper view.

The user can choose Destroy Component to delete the created Web Dynpro component Internal; after that the respective Component Interface view is removed from the view assembly.

At the end of the tutorial, the application is enhanced by a data transfer across component borders using External Context Mapping. In this enhancement, the inner Web Dynpro component shall display the number of previous component creations. This information is stored in the embedding component; the inner Web Dynpro component can access the information using External Context Mapping.

 Now start to develop the project structure of the Eventing example application using the Web Dynpro tools.
