             Summary: Wrong version assignment when multiple TAKEs transitions
                 Key: FLINK-6609
                 URL: https://issues.apache.org/jira/browse/FLINK-6609
             Project: Flink
          Issue Type: Bug
          Components: CEP
    Affects Versions: 1.3.0
            Reporter: Dawid Wysakowicz
            Assignee: Dawid Wysakowicz
            Priority: Blocker
             Fix For: 1.3.0


This test fails due to wrong version assignment for TAKEs from the same state.
