Hi, I have a boolean field 'classified' on sale order and my idea was that only users who are in the group that I created 'Classified quotations' can see records on tree view in which classified is true . I created two rules and I have no idea why it doesn't work. Here is the code:

 <?xml version="1.0" encoding="UTF-8"?>
<openerp>
   <data>

      <record id="sale_order_rule_group_classified_quotations" model="ir.rule">
         <field name="name">sale_order_rule_group_classified_quotations</field>
         <field name="model_id" search="[('model','=','sale.order')]" model="ir.model"/>
            <field name="groups" eval="[(4,ref('group_classified_quotations'))]"/>
         <field name="domain_force">['|',('classified','=',True),('classified','=',False)]</field>
      </record>

         <record id="sale_order_rule_no_group" model="ir.rule">
         <field name="name">sale_order_rule_no_group</field>
         <field name="model_id" search="[('model','=','sale.order')]" model="ir.model"/>
            <field name="groups" eval="[(4,ref('base.group_user'))]"/>
         <field name="domain_force">[('classified','=',False)]</field>
      </record>

   </data>
</openerp> 

What am I doing wrong?
