Summary: Subclasses of InternalWindowFunction must support OutputTypeConfigurable Key: FLINK-3977 URL: https://issues.apache.org/jira/browse/FLINK-3977 Project: Flink Issue Type: Bug Components: Streaming Reporter: Aljoscha Krettek Priority: Critical Right now, if they wrap functions and a wrapped function implements {{OutputTypeConfigurable}}, {{setOutputType}} is never called. This manifests itself, for example, in FoldFunction on a window with evictor not working. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
