Question: Does the add-on support Commerce Connect

[stefanolsen]

I am trying to use this add-on on a Commerce Connect 14 site, to add categories to product pages for rendering as search filters.

However, this only seems to work for single-select properties. As soon as I add a multi-select property the site crashes on start-up. This because Commerce Connect doesn't support properties of type IList<ContentReference> out-of-the-box.

Hi @stefanolsen,

The add-on targets CMS IContent and has no Commerce dependency, so Commerce Connect isn't officially supported/tested.

But this crash isn't category-specific — it's how Commerce handles list properties. CMS auto-backs IList with PropertyContentReferenceList; Commerce catalog content doesn't, so it needs the backing type declared explicitly or it can't map the type and fails on start-up. That's why your single-select ContentReference works but multi-select doesn't.

The fix is on your own content type — no add-on changes needed:

[BackingType(typeof(PropertyContentReferenceList))]
[UIHint(CategoryUIHint.Categories)]
public virtual IList Categories { get; set; }

([Categories] works in place of the UIHint too — the backing type controls storage, the category hint only the editor UI.)

Haven't verified the combo on Commerce 14 myself, but this is the standard fix for that mapping error.
