Communicating with Other iViews

The portal enables iViews running on the same page to communicate with each other, using JavaScript on the client. Web Dynpro provides a set of Java wrapper methods to enable an application to generate the JavaScript for client-side eventing.

Client-side eventing enables an iView to perform the following tasks:

Subscribing to a Client Event
Firing a Client Event

Restrictions

We recommended using client-side eventing only for occasional communications between Web Dynpro applications.
For more active communication, create a single Web Dynpro application with several views and use standard Web Dynpro mechanisms for communicating between views.
Due to JavaScript restrictions, all participants (the portal server and all used servers) must be in the same domain when client eventing is used.
Client eventing is supported only when the application is run in a browser.
