Hi Alessandro, With http://svn.apache.org/viewvc?rev=1303322&view=rev this should now work as expected. It would be cool if you could test this. My tests worked as expected.
regarding your question about the entity prefixes: This is only used by the ReferencedSiteManager component to decide based on the URI if an ReferencedSite need to be asked on requests for an entity. So it only affects requests for dereferencing entities via the "/entityhub/sites" endpoint. It is NOT used as base URL. In the case of "revyu" you can set "http://revyu.com/"; as prefix as all entities defined by this site do use this as common prefix. best Rupert On Tue, Mar 20, 2012 at 4:50 PM, Alessandro Adamou <[email protected]> wrote: > Thanks a lot Rupert, > > >> The answer is very easy.
