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

             Summary: CEP operators don't properly advance time
                 Key: FLINK-5033
                 URL: https://issues.apache.org/jira/browse/FLINK-5033
             Project: Flink
          Issue Type: Bug
          Components: CEP
    Affects Versions: 1.1.3, 1.2.0
            Reporter: Till Rohrmann
            Assignee: Till Rohrmann
            Priority: Minor
             Fix For: 1.2.0


The CEP operator don't properly advance time in case of watermarks. Arriving watermarks should trigger the triggering of timeouts and pruning of event sequences. However, this works only if an element has arrived in the meantime. This is a bug and the time should also be advanced in case that no element arrived before the watermark.
