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

             Summary: states of merging window and trigger are set to different TimeWindows on merge
                 Key: FLINK-4863
                 URL: https://issues.apache.org/jira/browse/FLINK-4863
             Project: Flink
          Issue Type: Bug
          Components: Streaming, Windowing Operators
            Reporter: Manu Zhang


While window state is set to the mergeResult's stateWindow (one of original windows), trigger state is set to the mergeResult itself. This will fail {{Timer}} of  {{ContinuousEventTimeTrigger}} since its window cannot be found in the window state.
