[jira] [Created] (ARROW-18265) [C++] Allow FieldPath to work with ListElement

Miles Granger created ARROW-18265:
-------------------------------------

             Summary: [C++] Allow FieldPath to work with ListElement
                 Key: ARROW-18265
                 URL: https://issues.apache.org/jira/browse/ARROW-18265
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Miles Granger
            Assignee: Miles Granger
             Fix For: 11.0.0


{{FieldRef::FromDotPath}} can parse a single list element field. ie. {{{}'path.to.list[0]`{}}}but does not work in practice. Failing with:

_struct_field: cannot subscript field of type list<....>_
Being able to add a slice or multiple list elements is not within the scope of this issue.
