[jira] [Commented] (FLINK-2891) Key for Keyed State is not set upon Window Evaluation

    [ https://issues.apache.org/jira/browse/FLINK-2891?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14968618#comment-14968618 ] 

Gyula Fora commented on FLINK-2891:
-----------------------------------

> In both the aligned and the general-purpose windows the key for the keyed operator state is not set when evaluating the windows. This silently leads to incorrect results.
