> Key: NIFI-4368
> URL: https://issues.apache.org/jira/browse/NIFI-4368
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Reporter: Mark Payne
> Assignee: Mark Payne
> Priority: Major
>
> I have the following record:
> {code}
> {
> "id" : 3,
> "numbers" : [1, 2, 3]
> }
> {code}
> I tried using UpdateRecord with a property name of "/numbers[1]" and a
> literal value of "8" but
> the data was not modified. It appears to be due to the fact that the
> ArrayIndexFieldValue class uses the following code:
> {code}
> @Override
> public void updateValue(final Object newValue) {
> getParentRecord().get().setArrayValue(getField().getFieldName(),
> getArrayIndex(), newValue);
> }
> {code}
> But the field was constructed using a field name of "numbers[1]" instead of
> "numbers".
