Dear community,

I have created a new "x_payment_date" in the "invoice" model which stores the invoice payment date.

In the Reporting/Invoices analysis section, I would like to group by x_payment_term.

So, in the developper mode, I have edited the search view and added the following line:

<filter string="PaymentDate" icon="terp-go-today" context="{'group_by':'x_payment_date'}"/>

But when using this filter, I get the following error:

Could you help me understand what is going wrong?

Many thanks in advance!
