The admin portlet in 2.6.5sp1 = JSF admin portlet? Does that currently supports EDIT_DEFAULT? "However, even with admin mode, uncheck users could not change the perferences, this is because all perferences are set to read-only if the user role is uncheck. I tried specifying read-only to false in portlet.xml, but still not success. " In very simple words, ADMIN mode could not change portlet perferences unless current user is logged in. For a user that is not logged in and attempt to change any perference in the ADMIN mode, it would result in a ReadOnlyException.
