Semantic of <a4j:portlet>?

[leolo]

Hi,

the documentation of <a4j:portlet> says:

"The main component purpose is implementation of possibility to create several instances for the same portlet on one page. "

Is there beside that main purpose another purpose?

I'm using jsf-portlet-bridge, which already gives me a unique namespace per portlet-window. Is there any reason why I also should use <a4j:portlet>?

Regards, LeoLo

In the portals, each portlet instance should has different ID's for HTML components and JavaScript functions/CSS classes. a4j:portlet is NamingContainer implementation, that prepends portlet namespace to all JSF components.
That component was obsolete because JSR-301 ( portletbridge ) specification requires that feature for a UIViewRoot.
