andreasc-kuehn opened a new issue, #5145:
URL: https://github.com/apache/hop/issues/5145
### Apache Hop version?
2.12.0
### Java version?
openjdk version "21.0.6"
### Operating system
Linux
### What happened?
Text File Input has «Accept filenames from previous transforms» section that
contains an option «Pass through fields from previous transform» which seems to
be logically unrelated to «Accept filenames», but is tightly linked in UI to
this option.
Explanation: When using Text File Input in a mapping and including this
mapping in a parent pipeline, all fields that existed before in the parent
mapping are swallowed.
In the UI it is not possible to set only «Pass through fields from previous
transform». It is necessary to also check «Accept filenames from previous
transforms».
But when set in the XML file, like this:
` <accept_filenames>N</accept_filenames>
<passing_through_fields>Y</passing_through_fields>`
then this is possible and it works without errors. I.e. the fields are not
swallowed and file names are still taken from «Selected files» table.
Therefore it seems to me, as if the UI dependency between «Accept Filenames»
and «Pass through fields from previous transform» is a mistake. Instead the
option «Pass through fields from previous transform» should be outside the
«Accept Filenames» section and not dependent on that one.
I would like to suggest to make the option «Pass through fields from
previous transform» independent from other fields, allowing to go on using
fields existing before this action.
