I have a scenario. I have a form view which only has a many2one field called users which shows all the products assigned to the user selected. Currently it is working. My Existing xml view is like this

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

     <field name="name">person.search</field>

     <field name="model">person.search</field>

     <field eval="7" name="priority"/>

     <field name="arch" type="xml">

        <form string="FORM DATA" version="7.0" >

            <field name="users"/>

            <button name="person_views" string="View" type="object" />

        </form>

    </field>

</record>

my button click code is like this:

def person_views(self,cr,uid,ids,context):

    domain=[]

    for id in ids:

        person_obj=self.pool.get('person.search').browse(cr,uid,id)

    per = int(person_obj.users)

    if per != False:

        query="select id,name from product_product where issue_to_equip="+str(per)+" OR assigned_to_it = "+str(per)+" OR assigned_to_soft = "+str(per)+" OR issue_to_book = "+str(per)+" OR person_phone ="+str(per)+" OR driver_vehicle = "+str(per)

    cr.execute(query)

    result=cr.fetchall()

    for p_id,name in result:

        domain.append((p_id))

return { 'type': 'ir.actions.act_window', 'res_model': 'product.product', 'view_type': 'form', 'view_mode': 'tree,form', 'target': 'current', 'context':ctx, 'domain':[('id','in',domain)] }

In this scenario products are being shown but on another page. My requirement is to show filtered values on same page and if user chagnes drop down, tree view also updates on button click. Is this possible in OpenERP7. Any hint to proper direction is appreciated. Thanks.
