I think Jboss Portal internally uses Hibernate Query Cache/Second level cache. Instead is it possible to enable lazy loading. Though i have not yet tested commenting query and second level cache. In case of lazy loading it may help to get rid of this issue of clustering of hibernate cache. Thomas / Prabhat, any comments on this.
