I'm interested how to display fields from the parent model in a form view.

in my model I have a relation

parent_id = fields.Many2one('parent.model')

if I try to show them in the form view I get only a link! The opposite works from the parent model to display children with the tree.

This displays only link?! 

<field name="parent_id">
	<field name="company_street"/>
	<field name="company_zip"/>
	<field name="company_city"/>
</field>
