[jira] [Created] (NIFI-8301) Escaping Parameter references not working

Mark Payne created NIFI-8301:
--------------------------------

             Summary: Escaping Parameter references not working
                 Key: NIFI-8301
                 URL: https://issues.apache.org/jira/browse/NIFI-8301
             Project: Apache NiFi
          Issue Type: Bug
            Reporter: Mark Payne
            Assignee: Mark Payne
             Fix For: 1.14.0, 1.13.1


If a processor/controller service attempts to escape a parameter reference, the escaping is ignored. For example, if I use GenerateFlowFile and I add 3 user-defined properties to it:

abc1 = #\{abc}

abc2 = ##\{abc}

abc3 = ${#\{abc}}

And I define a Parameter Context with a parameter: abc = xyz

The FlowFile generated should have the following attributes:

abc1 = xyz

abc2 = #\{abc}

abc3 = xyz

But the output actually has the following attributes:

abc1 = xyz

abc2 = xyz

abc3 = xyz
