Hi,

Im triying to create custom group by filters for my module, but im getting the following error message:

Traceback (most recent call last):
  File "/opt/openerp/70/openerp_prod/server/openerp/netsvc.py", line 292, in dispatch_rpc
    result = ExportService.getService(service_name).dispatch(method, params)

    res = fn(db, uid, *params)

    res = self._obj.execute(query, params)
ProgrammingError: syntax error at or near "GROUP"
LINE 6:             GROUP BY "trabis_lead_tendency_report_base"."com...

Apparently the query is wrong:

"SELECT min(trabis_lead_tendency_report_base.id) AS id, count(trabis_lead_tendency_report_base.id) AS company_name_count, "trabis_lead_tendency_report_base"."company_name" as company_name
            FROM "trabis_lead_tendency_report_base"
            WHERE
            GROUP BY "trabis_lead_tendency_report_base"."company_name"
            ORDER BY company_name"

There is nothing after the 'WHERE'

This is my filter view:

      <record id="view_lead_tendency_rec_search" model="ir.ui.view">
            <field name="name">trabis.lead.tendency.report.base.search</field>
            <field name="model">trabis.lead.tendency.report.base</field>
            <field name="arch" type="xml">
                <search string="Busqueda registro iniciativas">
                    <field name="company_name"/>
                    <field name="month_name"/>
                    <field name="date_year"/>
                    <group expand="0" string="Group By...">
                        <filter string="company_name" domain="[]" context="{'group_by':'company_name'}"/>
                        <filter string="month_name" domain="[]" context="{'group_by':'month_name'}"/>
                        <filter string="date_year" domain="[]" context="{'group_by':'date_year'}"/>
                </group>
                </search>
            </field>
        </record>

Any help will be greatly appreciated

Thanks.
