             Summary: Import from registry changes existing parameters when not allowed
                 Key: NIFI-16318
                 URL: https://issues.apache.org/jira/browse/NIFI-16318
             Project: Apache NiFi
          Issue Type: Bug
    Affects Versions: 2.11.0
         Environment: OS: RedHat (RedHat 8.10)
Kernel: 4.18.0
CPUs: 4 (Intel(R) Xeon(R) Gold 6348 CPU @ 2.60GHz)

GitLab integration via the GitLabFlowRegistryClient

When getting a flow from registry (gitlab integration) and leaving the "Keep existing Parameter Contexts" checked, still NiFi tries to change some parameters. 

!image-2026-09-08-14-06-38-786.png|width=530,height=393!

In a previous trial, when no other flows were running, it actually did change the parameter to the value from the registry. In the example above another flow was running, so it couldn't change it. 

The flow was not imported and the only way to import is to stop the other existing flow and let it update the parameter... This is dangerous and can result in wrong processing if parameters change to other values.

Expected behaviour: existing parameters should NEVER be overwritten when the option is checked. 
I've never noticed this behaviour in older nifi versions (v1)
