UI Component for Adaptive Filtering in (JPA)Container

I’m wondering if there’s adaptive filtering support in any of the container or addon. Currently evaluating JPAContainer to support dynamic query builder use case. A good example is showcased at http://www.smartclient.com/smartgwt/showcase/#featured_filter_builder_grid (this is SmatGWT showcase).



Core Vaadin or JPAContainer has now generic query builder UI component, but one should be rather easily doable. If you are using JPAContainer you could use QueryModfierDelegate to filter the container with all bells and whistles of JPA 2.0 Criteria API. If you remain with default Vaadin filters (aka Container.Filterable API), your query builder should work with any Vaadin container that supports it.
