Registering and Handling an Event

Registration for a Portal Event

To register your Web Dynpro application for a portal event, method SUBSCRIE_EVENT is available in interface IF_WD_PORTAL_INTEGRATION.

Generate an appropriate template using the Web Dynpro Code Wizard. You can then fill this with values.

Enter the namespace and the name of the event. The combination of namespace and event name must be unique. In addition, enter the name of the action that is to be triggered if this particular portal event is to be received. The corresponding action handler is then called automatically.

Handling a Portal Event

The parameters of a portal event are passed to action parameter WDEVENT using its method GET_STRING. Using optional parameter PORTAL_EVENT_PARAMETER, application-dependent information can be passed to the handler method. In the following example, this is the ID of a specific customer and this value is passed to the SHOWCUSTOMER method of the component controller, which is then called.
