Hello everyone,

I have an onchange method in product.template model:

    @api.one
    @api.depends('base_product')
    def onchange_base_product(self):
        if self.base_product:
            if self.base_product.product_variant_count > 1:
                self.base_has_variant = True
            else:
                self.base_has_variant = False

And I have three fields in form view:

<field name="base_has_variant" invisible="1"/>
<field name="base_product" domain="[('product_spesification', '=', 8)]" />
<field name="base_product_variants"
       domain="[('product_tmpl_id', '=', base_product)]"
       attrs="{'invisible': [('base_has_variant', '!=', True)]}"/>

In sale.order model when I added product in sale.order.line, I am clicking "create and edit". 
The window of product.template is opening and I am choosing base_product fields and there is nothing happens.
Compute method is not working and indirectly domain is not working for the field called by 'base_product_variants'.
