I have discovered a bug (and a workaround) concerning TempPathnameCreator version 1 in FME Form 2024.2.5.2.
First of all, because of the Security Hardening in FME 2026.2+ and Backport Versions (in this case FME Form 2024.2.5.2) the TempPathnameCreator must be updated to version 1 in all workspaces that use this transformer (for more information see https://support.safe.com/hc/en-us/articles/49062482561421-TempPathnameCreator-in-FME-2026-2-and-backports).
The bug I discovered is that in FME Form 2024.2.5.2 the attribute after 'Pathname’ is not exposed. This breaks all workspaces in FME Form 2024.2.5.2 using the TempPathnameCreator, even after updating the transformer to version 1. The workaround is simple: add an AttributeExposer to manually expose this attribute.
Edit: I notice that after manually exposing the attribute it often ends up as an extra attribute in my output. So the attibute has to be removed explicitly as well.
Note: I also tested this in version 2026.3.1.1; in that version the new attribute is exposed in TempPathnameCreator version 1. I don’t have any intermediate versions to test; perhaps other users can add some information about other versions below.
Edit: added a workspace to illustrate the bug and the workaround.
