             Summary: UI - Duplicate Variables
                 Key: NIFI-7056
                 URL: https://issues.apache.org/jira/browse/NIFI-7056
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core UI
            Reporter: Matt Gilman


When listing variables for a Process Group, the same variable could be listed twice. This can happen when the response from the server is very slow and the user clicks to see the Variable listing again. We should prevent this possibly by:

- Reviewing what uniquely identifies rows in the variable table and ensuring this cannot happen.
- If there are multiple outstanding requests only processing a single response.
- Consider approaches that would more clearly show when there is an outstanding request. This would prevent the action from being taken a second time. If we choose to implement this, we should do so in its own JIRA and link accordingly.
- Consider why the Variables response is taking so long to return. If we choose to investigate here, we should do so in its own JIRA and link accordingly.
