Hello everybody!!!

I want to order my view tree.

SO that, i tried the key 'default_order'.

Here is what i tried:

My Python class:

class test_momo(models.Model):

    _name = "test.momo"

    _order = 'temps_attente asc,id'

and in my view tree:

<record id="test_momo_tree" model="ir.ui.view">

        <field name="name">test.momo.tree</field>

        <field name="model">test.momo</field>

        <field name="arch" type="xml">

            <tree string="Request" default_order='temps_attente desc' colors="red:state=='refuse'; orange:state=='validate1'; green:state=='validate'">

  <field name="employee_id"/>

  <field name="request_date"/> 

         <field name="state"/>  

     </tree>

        </field>

    </record>

But i haven' got anything.
