Hi !

I've built a module which try to override the invoice report (pdf), to add some more fields to it.

However, sometimes, the file from the account module is used instead of my own file. That happens when I use the print button on the invoice (the red one when invoice is not printed yet). In this cases, the translation work properly, but this is not the file my module provides, so its wrong.

Now, when I use other print buttons, like the one in the "print" dropdown menu, or a custom print button, the pdf generated comes from my module, which is good, but not translated, which is bad, since I included the whole i18n folder in my custom module.

Now, I will show my code.

module/report/account_print_invoice.xml :

    <?xml version="1.0" encoding="utf-8"?>
    <openerp>
        <data>
            <record id="account.account_invoices" model="ir.actions.report.xml">
                <field name="auto" eval="False"/>
                <field name="model">account.invoice</field>

                    </header>

            </record>

    class account_invoice(osv.osv):

        def _voucher_ids(self, cr, uid, ids, name, args, context=None):
            result = {}
            for record in self.browse(cr, uid, ids, context=context):
                result[record.id] = []

            return {
                'type': 'ir.actions.report.xml',
                'report_name': 'custom.account.invoice',
                'datas': datas,
                'name': 'Invoice ' + record.number  ,
                'nodestroy' : True
            }

module/report/account_print_invoice.py :

    class account_invoice(report_sxw.rml_parse):
        def __init__(self, cr, uid, name, context):
            super(account_invoice, self).__init__(cr, uid, name, context=context)
            self.localcontext.update({
                'time': time,
                'cheque_no': self.cheque_no,
            })
        
        def cheque_no(self, voucher):
            try:
                cheque_no = voucher.cheque_number
                if not cheque_no:
                    # no value in field
                    return ''
                # value in field
                return cheque_no
            except AttributeError:
                # field not defined
                return False

    report_sxw.report_sxw(
        'report.custom.account.invoice',
        'account.invoice',
        'account_payment_method/report/account_print_invoice.rml',
        parser=account_invoice
    )

module/report/account_print_invoice.rml :

    <?xml version="1.0"?>
    <document filename="Invoices.pdf">
      <template title="Invoices" author="OpenERP S.A.(sales@openerp.com)" allowSplitting="20">
        <pageTemplate id="first">
          <frame id="first" x1="34.0" y1="28.0" width="530" height="786"/>
        </pageTemplate>
      </template>
      <stylesheet>
        [...]
      </stylesheet>
      <story>
      
        <para style="terp_default_8">[[ repeatIn(objects,'o') ]]</para>
        <para style="terp_default_8">[[ setLang(o.partner_id.lang) ]]</para>
        [...]
      </story>
    </document>

Note the "o.partner_id.lang", which I have not changed. The default lang of the database is the language I want the reports to be translated to. So my customers language is also set to the desired value.

I hope someone can help me fix this.

Thanks !

EDIT :

I also tried:

• Upgrading base module
• Upgrading my module
• Restarting server
• Synchronise terms
• Create new database

EDIT :

And of course I included the i18n folder from the account module.
