Subject NiFi Expression Language in UpdateAttribute
Date Thu, 11 Jun 2020 14:14:40 GMT
I wnat to create an attribute, format-type, which I hoped would be set 
based on the in-coming flowfile name:

     ${ ${filename:endsWith( 'xml' )} : ifElse( 'XML', 'JSON' ) }

If the in-coming flowfile name is /sample.xml/, the result is 
nevertheless and always

format-type = JSON

I want it to be XML, obviously. What have I screwed up in my NEL syntax?

(Yes, I have tried taking out all the white space.)
