Software Design and Components in XPages

In Domino 8.5.1 we will have a new Design Element "Component". This design element can be used in Portal, Mashups and the Notes sidebar as iWidget as well as composite component in the Notes client. In a component you pick 3 XPages (could be the same for all 3 cases) for read, edit and help mode. You also define the events the components "knows" and what type of event is is for that component: sending, receiving or both. An event is associated with a data type that can be primitive (String, number), JSON or a complex data type you defined with that component.
Components are the Lego blocks of your applications. A system designer now can quickly build "empty" components wire them up and then leave the implementation to the XPages development team. This could accelerate Domino's RAD capabilities further.
