-----------------------------------

             Summary: Query DSL should support groupBy for multi-valued properties
                 Key: ISPN-6015
                 URL: https://issues.jboss.org/browse/ISPN-6015
             Project: Infinispan
          Issue Type: Feature Request
            Reporter: Adrian Nistor
            Assignee: Adrian Nistor
             Fix For: 8.2.0.Alpha1, 8.2.0.Final


If a groupBy property is multivalued the entity will belong to multiple groups, one for each distinct value. 

Current implementation in 8.0.x and 8.1.x does not allow this and instead of providing invalid results grouping by multivalued property was disallowed (see ISPN-6008).
