Pierre Villard commented on NIFI-4383:
--------------------------------------
While working on this issue, I realized that the issue is not only limited to
simple types. Even if we are updating arrays of records, this won't work as-is.
Besides, if we have an array of records, and we want to update the first one
and the third one, we would use the following path: {{/records[1,2]}}. However,
the instances of ArrayIndexFieldValue object are not created successfully: the
index of each field is always set to 0. In the end, only the first record of
the array (with index 0) will be updated.
I'll update the description of this JIRA and submit a PR.
