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

             Summary: Join key selection for nested Tuples is broken
                 Key: FLINK-1186
                 URL: https://issues.apache.org/jira/browse/FLINK-1186
             Project: Flink
          Issue Type: Bug
          Components: Java API
    Affects Versions: 0.7-incubating
         Environment: LocalExecutionEnvironment
            Reporter: Robert Waury
            Priority: Minor


When using strings to select join keys of nested tuples (e.g. "f0.f1") an incorrect join key is chosen and the operator produces an erroneous result.

The join works fine when using KeySelectors.

I will attach a program to reproduce the bug.
