Alex Savitsky resolved NIFI-5731.
---------------------------------
Resolution: Duplicate
> Support List-typed fields for Array coercion
> --------------------------------------------
>
> Key: NIFI-5731
> URL: https://issues.apache.org/jira/browse/NIFI-5731
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core Framework
> Affects Versions: 1.7.1
> Reporter: Alex Savitsky
> Priority: Trivial
>
> This Jira concerns the nifi-record module specifically.
> Currently, the toArray method ofÂ
> org.apache.nifi.serialization.record.util.DataTypeUtils does not support
> values of type java.util.List to convert to Object[], despite the conversion
> being a trivial one-liner:
> {code:java}
> return ((List) value).toArray();
> {code}
> The Record being converted doesn't always have the control to enforce all its
> arrays being actual arrays and not collections (e.g., if the Record was
> created in Groovy), and it would be nice to have it converted on the fly,
> rather than having to transform it manually.
