Hi,

In Odoo8 I am receiving this error:

Odoo Server ErrorTraceback (most recent call last):

Error context:

View `sale.order.form`[view_id: 575, xml_id: sale.view_order_form, model: sale.order, parent_id: n/a]

What does this mean and how do I resolve it? As far as I know, I have not changed anything. I duplicated a Routing for a Bill of Material. I did not modify any source files.

Thank you
