Fieldvalueselectortype on productmodel

Questions
1

How can I use FieldValueSelectorType value on the productmodel?

It says here in the description that it

“Gets or sets the field value selector.”

But its defined as:

public virtual ProductModel.FieldValueSelectorType FieldValueSelector { get; }

Im interested in having it as VariantAndBaseProduct = 8 How can I make that happen?

Version 7.7.1

Yes it is only “get” we must fix the documentation.
This needs to be set on ProductModel initialization:

public ProductModel(BaseProduct baseProduct, Variant selectedVariant, FieldValueSelectorType fieldValueSelector, Lazy<ProductFieldTemplate> fieldTemplate, Lazy<ProductDisplayTemplate> displayTemplate)
        {
            BaseProduct = baseProduct;
            SelectedVariant = selectedVariant;
            FieldValueSelector = fieldValueSelector;
            _fieldTemplate = fieldTemplate;
            _displayTemplate = displayTemplate;
        }

What is the FieldValueSelectorType set to when using ProductModelBuilder?

Not sure what you mean but this gets set in ProductModelBuilderImpl.cs depending on what method (eg. BuildFromVariant or BuildFromBaseProduct) is called to generate the ProductModel.
Why do you need to set FieldValueSelectorType your self, what are you trying to do?

I would like to know what FieldValueSelectorType is set to when using the different methods in ProductModelBuilder
