1.9.1 : An old bug regarding hierarchical classification

[fplanglois]

An old bug that's been bothering me for a long time.

I extensively use hierarchical classification within the image itself through IPTC and XMP.

To do this, the settings are as follows:

xnview classement hierarchique.png (41.78 KiB) Viewed 203 times

IPTC: Keywords & Categories
Keywords: diving|2025|CF, diving|2025|CF|selection 1, diving|2025|CF|selection 2, diving|2025|CF|mobile fauna, diving|2025|CF|mobile fauna|selection

We can see that this image belongs to six categories.

I want to remove it from a category.
My procedure is as follows:
- I go to the relevant category using the "Catalog Filter" panel.
- I select the image, right-click, and select Remove from Category.

xnview classement hierarchique2.png (210.3 KiB) Viewed 203 times

- Metadata > Update File from Catalog

So far, so good.

The problem occurs if you try to delete the very last category using the same procedure.
If the category you're trying to delete is the last remaining category, after deleting and updating the file, the last category remains in the IPTC keywords (not in the XMP).

The workaround I found is to delete the category via the categories panel:

But this is clearly a bug.

Thanks to your detailed description I can reproduce the problem.

After various tests, this old bug can no longer be reproduced. I can now catalog without fear!

Merci.
