Grouping items in rules - customer data structures like pojo

Not :slightly_smiling_face:, :confused:

I recommend reviewing

There is no need to have separate rules. There is probably no need for the lambda. And there is likely no need for the nested loops.

Another approach is to put the static values in a .map file and access them by a key using the transform Action similar to documented in Design Pattern: Human Readable Names in Messages.
