Input Records in Processor with input other than String

MattiaMi89 — Fri, 02 Jan 2026 14:45:42 GMT

I'm developing a Custom Component (a processor) that has as input a Record:

Record is really simple it has two fields:

KEY: type String

VALUE: taype Arraylist<String>

To test this component I set a simple tJavaFlex component that generate 1 row the is connected to my custom component

bellow an extract of the code of the tJavaFlex

row.KEY="key";

ArrayList<String> data = new ArrayList<>();

data.add("1");

data.add("2");

row.VALUE=data;

Alas, when I run the job, my component recevices a Record that contains the KEY only, the VALUE field seems to disapper.

The first action in my @ElementListener method is printing (on sysout) the record and its schema and I can't see VALUE nor in record neither in schema.
