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
● 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.
