Catalog field in ProductModel

[Mpcasas]

Hi guys!

I've seen the fields catalog and cataloVersion defined in catalog-items.xml for Product type. The first one, catalog fields, is definned as private, so this field doesn't appear in backoffice and it doesn't have get and set methods.

So I create an example product and I can see it in the backoffice, and when I search with the flesible search in the hac I can see the field catalog isn't empty. If the field is private, how and where is fullfill this field?

Thanks!!

You normally don't use `catalog`. Instead, you use `catalogVersion`, which is a CatalogVersion type that has Catalog in it, plus the version.
