I added a custom field in "base.view_partner_form" named "ob_CRM02-c01-004" and want to show the value of this field in the kanban view "base.res_partner_kanban_view".
In XML i just tried:
<h4 class="oe_partner_heading"><a type="open"><field name="ob_CRM02-c01-004"/></a></h4>
But it shows me "NaN" at which
<h4 class="oe_partner_heading"><a type="open"><field name="street"/></a></h4>
where "street" is a predefined field is working.
How can I display the Value of my custom field there?
