hi !
I have in my new module a functional field, whene i put it in my tree view i can't open my view.
here the action code :
    <record id="my_module_normal_action" model="ir.actions.act_window">
    <field name="name">My module</field>
    <field name="type">ir.actions.act_window</field>
    <field name="res_model">mymodule</field>
<field name="domain">[('my_field','=',True)]</field>
    <field name="view_type">form</field>
    <field name="view_id" ref="my_module_tree_view"/>
    <field name="search_view_id" ref="my_module_search_form_view"/>
</record>
my code xml :
<record id="my_module_tree_view" model="ir.ui.view">
            <field name="name">my.module.tree</field>
            <field name="model">mymodule</field>
            <field name="type">tree</field>
            <field eval="7" name="priority"/>
            <field name="arch" type="xml">
                <tree string="my module">
                   <field name="my_string"/>
            <field name="my_field"/>
                </tree>
            </field>
        </record>
in my python code :
  'my_field': fields.function(_get_concatenate_values, method=True, string='Reference', type='char'),
this is the function's code :
def _get_concatenate_values(self, cr, uid, ids, field_name, arg, context=None):
            records=self.browse(cr,uid,ids)
            result={}
            for r in records:
                if(r.field1 and r.field2):
                    result[r.id]= str(r.field1.name)+'.'+ str(r.field2.name)
                return result
"my_field"'s value is the concatenation of the two fields :field1 and field2
thanks for your reply.
 
                        
What version of OpenERP are you using? Your field is called 'code' but you use 'my_string' and 'my_module' in the view?
I use V6.0.2 , my feild's name is 'my_field', 'my_sring' is an other field in my module. so I rectify the python code : 'my_field': fields.function(_get_concatenate_values, method=True, string='Reference', type='char'),
