Posting a bulletin from a script in ExecuteScript

[Jake Kugel]

Hello,

I've created a Python script to process flowfiles within an 
ExecuteScript processor following the good example from here:

http://funnifi.blogspot.com/2016/03/executescript-json-to-json-revisited.html

I'm curious if it is possible for my script to post a bulletin to the 
ExecuteScript processor in the event of an error.  Is it possible for a 
script within ExecuteScript to post a bulletin, or are bulletin only 
intended for the nifi framework itself to display errors?

Thank you,
Jake
