[GitHub] [hop] enricomariam42 opened a new issue, #2102: [Bug]: Can't inject "Group field" field in "Row denormaliser" transform

enricomariam42 opened a new issue, #2102:
URL: https://github.com/apache/hop/issues/2102

   ### Apache Hop version?
   
   SNAPSHOT-20221221
   
   ### Java version?
   
   openjdk version "11.0.9.1" 2020-11-04 OpenJDK Runtime Environment (build 11.0.9.1+1-post-Uos-1deb10u2) OpenJDK 64-Bit Server VM (build 11.0.9.1+1-post-Uos-1deb10u2, mixed mode, sharing)
   
   ### Operating system
   
   Linux
   
   ### What happened?
   
   Injecting "Group field" with a constant value in "Row denormaliser" transform has no effect and the group is missing in the injected transform.
   
   Workaround: define the group in a field (e.g. in a "Add constants" transform) and select that in the metadata injection transform.
   
   (Migrated from https://issues.apache.org/jira/browse/HOP-3860)
   
   [injection.zip](https://github.com/apache/hop/files/10287743/injection.zip)
   
   The attached pipeline `denormalizer_template.hpl` containing a "Row denormaliser" is injected in the two ways:
   - with a constant value `inject_denormalizer_not_working.hpl` produce `injected_denormalizer_no_group.hpl` 
   - with the group in a field `inject_denormalizer_working.hpl` produce `injected_denormalizer_with_group.hpl` 
   
   Obtained (output of injected_denormalizer_no_group.hpl):
   group | SNS | SERVIZI SAN | RicaviSan
   -- | -- | -- | --
   3A120 | -13576,2 | -322,8 | 3,5
   
   Espected (output of injected_denormalizer_with_group.hpl): 
   group | SNS | SERVIZI SAN | RicaviSan
   -- | -- | -- | --
   3A120 |   |   | 3,5
   2G112 | -13576,2 | -322,8 |

   I understand. Letting input a constant value lead to an unexpected behavior, though. 
   So, block the use of a constant filed if lists expected, or map a constant to a single value list, or split it to a list of fields based on special char can be possible?
   I don't think document it is enough, even if there is a way around.

   Bit of an annoying issue, for lists it expects data rows as it does not really know how many fields to add when using a constant. I'm leaning towards "works as intended". Though I understand the edge case when you only need 1 value
