Signed-off-by: Mark Payne <[email protected]>
> UpdateRecord - cannot update arrays elements
> --------------------------------------------
>
> Key: NIFI-4383
> URL: https://issues.apache.org/jira/browse/NIFI-4383
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 1.3.0, 1.4.0
> Reporter: Pierre Villard
> Assignee: Pierre Villard
> Labels: records
>
> At the moment, if trying to use the update record to update the elements of
> an array it won't have any effect.
> Input:
> {noformat}
> {
> "numbers" : [ 1, null, 4 ]
> }
> {noformat}
> Parameters:
> ||Path||Value||Expected output||
> |{{/numbers[*]}}|{{8}}|{{"numbers" : [ 8, 8, 8 ]}}|
> |{{/numbers[1]}}|{{8}}|{{"numbers" : [ 1, 8, 4 ]}}|
> |{{/numbers[0..1]}}|{{8}}|{{"numbers" : [ 8, 8, 4 ]}}|
> |{{/numbers[0,2]}}|{{8}}|{{"numbers" : [ 8, null, 8 ]}}|
> When elements of the array are records, it's possible to update fields of the
> record but not the record itself as-is.
> Also in the MultiArrayIndexPath implementation, index of array elements is
> not correctly provided. Because of that, wrong elements of the array could be
> updated.
