Setting Declarations in the Form View Controller 

Before designing the view and implementing the view controller, you must first make several declarations. To trigger an event from the user interface, you need an action. Executing the action triggers an event whose parameter value is stored in the view controller context as a value attribute. To be able to trigger the InnerEvent (defined earlier in the component interface controller) in the Form view controller, you must define an appropriate controller usage.

Procedure

To display the perspective views for the Form view in the Web Dynpro tools, in the Web Dynpro Explorer, select the node WebDynpro_Eventing ® Web Dynpro ® Web Dynpro Components ® Internal ® Views ® Form.
