             Summary: Provide visual indication of variable registry usage (vs flowfile attributes) in the UI
                 Key: NIFI-6230
                 URL: https://issues.apache.org/jira/browse/NIFI-6230
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Core UI
            Reporter: Ed Jackson
         Attachments: italic-attrs.PNG

When configuring a processor, one often needs to reference variables from the variable registry as well as flowfile attributes.  For example when configuring a Kafka processor, one might use ${kafka-brokers}.  However, it is not immediately clear if the value for `kafka-broker` will originate from the variable registry or from an incoming flowfile attribute.

Although, it would be fairly trivial to back out of the modal and right click, view variables, etc... I think it would be helpful to indicate to the user when a variable is being referenced.

 

Alopresto had suggested using italics on slack.  Attached mock up of italics.

In this case, the ${var-table-name} is a variable registry entry and ${ff-attr-name} is a flowfile attribute.  The italics style allows the user to quickly discern the difference.
