This importation works very well in my custom module :
<?xml version="1.0" encoding="utf-8"?>
<openerp>
<data>
<record id="stock.stock_location_route_tree" model="ir.ui.view">
<field name="name">stock.location.route.tree</field>
<field name="model">stock.location.route</field>
<field name="arch" type="xml">
<tree string="Routes">
<field name="sequence" widget="handle" />
<field name="id" />
<field name="name" />
<field name="company_id" />
<field name="product_categ_selectable" />
<field name="product_selectable" />
<field name="warehouse_selectable" />
<field name="push_ids" />
<field name="pull_ids" />
</tree>
</field>
</record>
</data>
</openerp>
But if I add this field :
<field name="sale_selectable"/>
I get an error :
[.......]
Error details:
Field `sale_selectable` does not exist
[.......]
If I add the same line via the backend, in Settings->Views, it works!
How could it be possible?
