Identifying (GetFeatureInfo) on a WMS layer in the map only shows data in columns with a lowercase title

[mbrunger]

Clicking in the map to identify the table of a WMS layer shows all the columns but only the columns with a lowercase title show the data. Columns with one or more capital letters in the title show the '-' no data symbol (see screenshots) while they actually contain data. I tested with WMS-services from different organizations to rule out an issue with the services. I also compared different GeoNetwork versions and this behavior seems to exists only in version 3.12.x starting from 3.12.10. In version 3.12.9 and 4.0 it works fine and data in columns with capitals is shown properly.

Steps to reproduce the behavior:

1. Start GeoNetwork and go to the map
2. Add a WMS service layer. For example a layer from https://geodata.zuid-holland.nl/landelijk_gebied/wms? or https://service.pdok.nl/rws/weggeg/wms/v1_0?
3. Click in the map on a location with data.
4. Look at the table. In GeoNetwork 3.12.10 and 3.12.11 only the columns with lowercase titles show the data. The columns with capitals show no data ('-').

Test environments:

• GeoNetwork 3.12.11 server installation opened with Chrome on Windows -> issue exists
• GeoNetwork 3.12.10 Docker installation opened with Safari on Mac OSX -> issue exists
• https://geometadatensuche.inspire.gv.at/metadatensuche (version unknown) -> issue exists
• http://geocatalog.webservice-energy.org/geonetwork (version 4.0.5.0) -> works fine
• https://services.data.shom.fr/geonetwork (version 3.12.9) -> works fine

@mbrunger I suspect is related to the 2 latest changes in:

https://github.com/geonetwork/core-geonetwork/commits/3.12.x/web-ui/src/main/resources/catalog/components/viewer/gfi/FeaturesLoader.js

• 3ac2ccb
• ce87308

You can try to revert these 2 changes to check if works as expected.

I see the original PR for main brach is a bit different, as the code looks different in both versions:

• 4.x: When identifying on a layer from a metadata with a linked feature catalog record, use case insensitive comparison between the feature catalog column definitions and the WMS FeatureInfo response. #6801
• 3.12.x: [BP] When identifying on a layer from a metadata with a linked feature catalog record, use case insensitive comparison between the feature catalog column definitions and the WMS FeatureInfo response. #6802

I would recommend upgrading to GeoNetwork 4.2.x if that is an option.

Thanks @josegar74

Reverting the 2 changes you mentioned has made it work. Data from all columns (snakecase and no snakecase) is now visible again.
