[Bug]: Mail transform zip filename error #5664
Description
Apache Hop version?
hop-client-2.16.0-20250902.091134-1
Java version?
openjdk version "17.0.16" 2025-07-15
Operating system
Windows
What happened?
In Mail transform, setting the field for the name of the zip file results in "Zipfilename is empty!" error.
It seems that the control for the missing value of the "zip filename" field is in place even if the "zip filename field" is enforced.
No error rises if there is a value in the the "zip filename" field.
