alopresto commented on issue #3825: NIFI-6782: Added repeat() String EL function
URL: https://github.com/apache/nifi/pull/3825#issuecomment-543913272
 
 
   I did a local build and tested this and I am experiencing odd behavior. 
While the code complete does suggest `repeat` and has the correct 
documentation, when I execute a `GenerateFlowFile` processor using it, I get `0 
byte` content regardless of using the single or double parameter invocation. 
   
   I've attached the sample flow I was using and a few screenshots.
