Changing the context path of Liferay (root_path) to anything other then '/' disables the configuration facilities in the portal.
-You cannot use any of the blue configuration panes in the control panel (nothing happens on select)
- On "Add -> More..." the list with available portlets drops down but selecting one of them (e.g. Collaboration) the list does not open.
This worked with Liferay 5.2.3, Liferay 6.0.0 preview and fails in Liferay 6.0.1 candidate.
I used a clean Liferay 6.0.1 Jboss bundle installation and made minimal configuration changes to set the context path to "flow" by changing the context path in jboss-web.xml, the root_path in web.xml and the "ctx" portal-ext.properties
The portal then is available in http://localhost.8080/flow. I can successfully log in but a lot of configuration facilities do not work anymore.
