Comparing the new and the old client-side programming model

Compare the current client-side programming model to the client-side programming model from previous versions.

WebSphere Portal introduced a client-side programming model. It allowed you to use AJAX techniques in portlets. You can use it for working with portlet preferences, user profiles, and the portlet state including the portlet mode, the window state, etc. Advantages of using the client-side programming model include an improved user experience by faster response times and performance. Portlets render faster, as the portal does not re-render the whole page, but only the aspects of the portlet that changed by the user request.

WebSphere Portal v7.introduces a new client-side programming model that allows you to use static and dynamic content and portlets and widgets on the same page and on pages with the same theme. It deprecates the programming model from the previous versions. Although the old model still works, developers are encouraged to write new code to comply with the new APIs. The following sections compare the old API with this new API and explain how you can do things with the new API that you did with the old API.
