Hi all,
I am new to CAF development. I have a application which has 2 portlets configured in a page. I am doing some business logic, and based on the business logic, i want to refresh second portlet. I dont want to refresh whole page for doing so.

Can anybody suggest me a solution for this?

Thanks

Thanks for the reply Eric,
My requirement is somewhat different.
I have to check whether a user is entitled to do access any functions in my application. if not, i have to redirect to error page.

If you are talking about redirecting during the rendering of your header portlet, then you will probably have to do a client-side redirect from javascript. A server-side redirect may not work since the page has already been partially rendered.

Add a Script Block control to your CAF view to change the current page whose value is something like this:

window.location = "/alias_of_error_page";

getFacesContext().getExternalContext().redirect();

Provide a valid alias in the place of
