I had to rollback your changes as they require too many modifications of the core code base and I want to keep it for now stable. The other major constraints that needs to be respected: - the ui server should have its own module that does not depend upon core or theme framework and introduce its own concepts - testing it in core should be done using a core-uiserver module (temporary) that reuses core + uiserver module and produce a jboss-portal.sar that mixes both - the protocol between the consumer and producer (let's call them like in WSRP) needs to be done really using a protocol modeled under the form of data objects (I am going to describe that in another post). - in the core-uiserver part, the current core controller should be reused with with separate implementation of ResponseHandler that would adapt the current core controller command framework to the ui server protocol.
