Pierre Villard commented on NIFI-5880:
--------------------------------------
In your GenerateFlowFile, just set:
{noformat}
abc = a,b,c
{noformat}
(no single quotes)
Then in the UpdateAttribute, it must be:
{noformat}
matched = ${anyDelineatedValue(${abc}, ','):equals('a')}
{noformat}
This will work as expected. Let me know if that's ok for you.
