I have a user who has only the following two organizational roles (no other roles):
In portal-ext.properties, the following two properties are set:
User logs in and navigates to the organization: Places->[the organization]->Public Pages.
User clicks 'Add Page'.
New Page appears.
User enters page name.
User hits 'save'
In the UI, nothing happens.
In the server log, you get two entries:
13:48:30,546 ERROR [PortalRequestProcessor:483] Remote address 127.0.0.1
13:48:30,546 ERROR [PortalRequestProcessor:485] Invalid path was requested /common/error
BTW: creating a new page works for this user if the page is created via control panel, selecting organizations (under category portal)
and then selecting actions->Manage Pages for that organization.
