I found a way to solve my problem.
I needed to check the size of products to display only templates that can handle this list. Some can handle only one products and their field "multi" is set to False (or 0).
The domain i used to do this is :


Thank you again for your help ;)

I guess, you can't achieve desired behavior just using XML. 'label.products' is not good.
The easiest way is to make a computed field to calculate len and place this new field to a form. E.g.:

in your Model:
def _compute_len_products(self):
  for label in self:
  label.len_products = len(label.products) len_products = fields.Integer(compute=_compute_len_products, store=True)

in XML:
<field name="len_products" invisible="1"/>
<field name="template" domain="[("len_products",'=',1)]"/>

Quite simple in fact .. :)

I though it could have been done in XML directly. Thank you !

It doesn't work :'(

it loads field 'len_products' from template class :

ValueError: Invalid field u'len_products' in leaf "<osv.ExtendedLeaf: (u'len_products', u'<=', 1) on label_template (ctx: )>"
