-----------------------------------

             Summary: Updating variables does not properly resolve referencing components causing variable updates to incorrectly fail
                 Key: NIFI-6194
                 URL: https://issues.apache.org/jira/browse/NIFI-6194
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
    Affects Versions: 1.9.1
            Reporter: Charlie Meyer


steps to reproduce:

 

There is attached XML template for a flow. It contains:
 * Root PG
 ** variable named {{my_id}} in the variable registry
 ** an updateattribute processor that references {{my_id}}
 ** a nested process group
 *** overrides {{my_id}} in its variable registry
 *** an update attribute processor that references {{my_id}}

 # load the template into a clean nifi
 # start up the 2 updateattribute processors
 # open the root PG's variable registry and attempt to change the value of variable named {{my_id}} 
 # itll show only 1 processor references it, which is correct. 
 # the update request will incorrectly fail as it resolves the updateattribute processor in the nested processgroup as referencing the {{my_id}} variable in the root pg, even though it is actually referencing the overridden {{my_id}} in the nested PG where it is provisioned
