> UpdateAttribute Advanced Configuration does not recognize Parameters

> Key: NIFI-13547
> URL: https://issues.apache.org/jira/browse/NIFI-13547
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 1.21.0, 1.23.2
> Reporter: Christof Dilcher
> Priority: Minor
> Attachments: Parameter_Test.json.zip,
> direct_use_of_parameter_in_UpdateAttribute.jpg,
> parameter_used_in_expression_language_in_UpdateAttribute.jpg
>
>
> When using UpdateAttribute Advanced Configuration and configuring a rule, a
> parameter value (from the parameter context) is not directly accessible. When
> referencing a parameter in the "Value" section of the "Action" part of the
> "Rule" setup (see screenshot direct_use_of_parameter_in_UpdateAttribute.jpg),
> it is instead interpreted literally and not replaced with the parameter value
> as would be expected.
> The value can be accessed however when the parameter is referenced within an
> expression language term (see screenshot
> parameter_used_in_expression_language_in_UpdateAttribute.jpg).
> IMHO the parameter value shall be directly accessible within this
> configuration. If this is intended behavior, this shall be mentioned in the
> documentation as it is not obvious to the user that in this place the
> expression language has to be used in order to access the parameter value.
> I have attached the flow definition to this ticket (see
> Parameter_Test.json.zip) for reference. The corresponding parameter context
> just contains one parameter named "replacement_parameter" with its value
> 'some replacement value'.
