Charlie Meyer commented on NIFI-6194: ------------------------------------- i just downloaded 1.9.0 and replicated it there as well, so this was not introduced in 1.9.1 > 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 > Priority: Major > Attachments: nifi_bug.xml > > > 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 > > In the update request, the first steps succeed: > {noformat} > {"description": "Identifying components affected","complete": true}, > {"description": "Stopping affected Processors","complete": true},{noformat} > But the {{affectedComponents}} section of the update-request only shows 1 > processor which is correct. The {{"Applying Updates"}} step of the update > fails and the error message references the uuid of the processor in the > nested PG which is referencing the overridden value. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
