Hello,

I am using V8 and I would like to read the value of a selection field from another form, normally which types should I use ? field.related or field.many2one or both of them.

The original model is "product.template" , I would like to know the value of the field "type" which is a selection field in the model.

the other model is "product.supplierinfo", It already contains a field which is defined as follows:

'product_tmpl_id' : fields.many2one('product.template', 'Product Template', required=True, ondelete='cascade', select=True, oldname='product_id'),

I extended this model to add a new field which will hold the value of the selection field in product using the incoming code:

product_type = fields.Selection(related='product_tmpl_id.type',store=True)

But when I open the form I don't find the selected type value, I just find the selection drop-down menu without selected option.
