Most of the OpenERP reports are giving generating this error:

Field 'invoice_line' does not exist in object 'browse_record(res.partner, 451)'

(<type 'exceptions.attributeerror'="">, AttributeError(KeyError("Field 'invoice_line' does not exist in object 'browse_record(res.partner, 451)'",),), <traceback object="" at="" 0x7fa8a1802200="">)

The issue has been traced to the header/footer. Under Company - Edit, clicking Preview Header/Footer, it will fail with this error. Every report that uses a header fails.

I've tried replacing the RML with the stock versions. And I can't find any reference to invoice_line.

Where else can I look to find an error related to the header/footer?

Thank you,
