How to apply custom sorting to a MultiSelect Lookup in Freedom UI?

Hello Community,

I'm struggling with the MultiSelect Lookup component in Freedom UI. I need to sort the available options in the dropdown by a specific Integer column (NcsOrden) instead of the default Name column.

I've already successfully implemented the Predefined Filter in the viewModelConfigDiff to filter the records, but I can't find a way to change the sort order.

What I've tried so far:

• crt.LoadDataRequest Handler: Adding a type: "sorting" object to request.parameters. This triggers a TypeError regarding a 'type' property being undefined in the core JS.
• viewModelConfigDiff: Adding sortingConfig to the attribute. This causes the page to crash with a TypeError in _loadStaticModel.

Has anyone successfully managed to sort a MultiSelect list by a column other than the Primary Display Column? If this is not currently supported via No-Code or standard Handlers, what would be the recommended approach?

Thanks in advance!
