---------------------------------
Assignee: Timea Barna
> Hide some properties in CSVReader when built-in CSV Format is selected
> ----------------------------------------------------------------------
>
> Key: NIFI-8763
> URL: https://issues.apache.org/jira/browse/NIFI-8763
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Reporter: Peter Gyori
> Assignee: Timea Barna
> Priority: Minor
>
> In CSVReader controller service, the value of the CSV Format property can
> either be 'Custom Format' or some built-in format with predefined parameters
> (RFC 4180, Microsoft Excel, etc.). When 'Custom Format' is selected, the
> user-defined (or default) values of other properties, like 'Value Separator',
> 'Record Separator', 'Escape Character', etc. are used. However, when one of
> the built-in formats is used, the user-defined (or default) values of these
> properties are ignored and the format-specific settings are used (e.g. with
> RFC 4180, the delimiter is the comma, and the escape character is not set)
> yet, the user can still manipulate the values of these properties of the
> controller service but they will be ignored which might lead to confusion. It
> would make sense to hide the properties that cannot be overridden when a
> built-in format is selected.
> Also, the settings of the built-in formats do not appear in the NiFi
> documentation. The built-in formats come from a 3rd party library
> org.apache.commons.csv.CSVFormat (in case of the Apache Commons parser). It
> would be useful to add the link to the CSVReader documentation that points to
> these settings.
