Comment 13 for bug 941817

I'm confirming that this bug still exist in OpenERP 7. 0.

Until the fix released, here is a workaround. Put this in a custom module, in an xml file. Make sure it is included in __openerp__.py 's "update_xml" list.

<?xml version="1.0" encoding="utf-8"?>
<openerp>
    <data>

        <record id="account.act_proforma2" model="workflow.activity">
            <field name="wkf_id" ref="account.wkf"/>
            <field name="action">write({'state':'proforma2'})
button_reset_taxes()</field>
        </record>

    </data>
</openerp>
