[GitHub] [incubator-streampipes] amkcpu opened a new pull request #21: Clear sortedEventKeys before adding new keys

[GitBox <gi...@apache.org>]

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.
