Hi All, What is the correct way to include the document number in the footer for qweb reports. This would be used under sale orders, invoices and picking documents. Because in a sale order the field is called number (sale_order.name eg S0/12345) and in an invoice is is called a number (account_invoice.number eg VKB/171234 )

I tried this. But when i print qweb stops without warning when a field is not available in the current table. 

This is in my footer:

<span t-if='o.number' t-raw='o.number'/>

<span t-if='o.name' t-raw='o.name'/>

I check for the field but still the printing stops.

Best regards,

Maarten
