amkcpu opened a new pull request #21: URL: https://github.com/apache/incubator-streampipes/pull/21
### Purpose Fixes an issue that appears when more than one stream is connected to a Siddhi processing element. Before, when the second stream is added to Siddhi by creating the "define stream..." string, keys from the first stream remained in the `sortedEventKeys` ArrayList. This resulted in a `NullPointerException` because these keys could not be found in the `typeMap` HashMap. ### Approach Clear `sortedEventKeys` before adding new keys by calling the `ArrayList.clear()` method. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
