try this.

from openerp.osv.orm import setup_modifiers

if doc.xpath("//field[@name='order_line']/tree//field[@name='product_id']"):

node = doc.xpath("//field[@name='order_line']/tree//field[@name='product_id']")[0]

node.set('invisible', '1')

setup_modifiers(node, res['fields']['product_id'])

res['arch'] = etree.tostring(doc)

return res

OR

attribute name="invisible">1</attribute>

</xpath>

I hope it's useful for you.

I can't do it in the xml file, because i have to show/hide the column, depending of attributes like company_id.
Since now i can't find 'order_line <tree> columns in the doc.xpath, so i cannot replace or hide the fields.

Kind regards.
