Product / Bill of Materials button raises error

[Leigh Willard]

v7.0 stable

Create a BOM for a product.

Go to Sales / Products / Products, this will open the products in Kanban view with the GROUP-BY Category.

Select your product, then click on the button "Bill of Materials". This raises an error (see below),.

However, if during the Kanban view you UNSELECT the group-by, there is no error.

Here is the error trace:

Ok
