Hi guys 
i m trying to implement a new filter on order by adding an email and a phone filter in my order list view.
I have an error : 

This domain is syntactically not correct: [[u'state', u'not in', [u'draft', u'sent', u'cancel']], u'|', u'|', [u'partner_id.email', u'ilike', u'OFR']]

Here is my code :

​

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

<field name="priority">100</field>   

 <field name="model">sale.order</field>    

<field name="inherit_id" ref="sale.view_sales_order_filter"/> 

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

 <xpath expr="//field[@name='name']" position="replace"/>   

 <xpath expr="//field[@name='partner_id']" position="before"> 

 <field name="name" string="Sales Order" filter_domain="['|',('name','ilike',self),('client_order_ref','ilike',self)]"/>        

<field name="name" string="origin" filter_domain="['|',('origin','ilike',self)]"/>           

 <field name="name" string="email" filter_domain="['|',('partner_id.email','ilike',self)]"/>  

 <field name="name" string="phone" filter_domain="['|',('partner_id.phone','ilike',self)]"/>  

 </xpath>   

 </field>

</record>​

Could you tell me why i have this error in all my filters please?
Thanks a lot 
Thomas
