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>?
That component was obsolete because JSR-301 ( portletbridge ) specification requires that feature for a UIViewRoot.
