I am using Odoo 8.

I have added the field remaining_total to the account.analytic.account view, but I would like to know how to filter by that field.

I would like to see only contracts that have been fully invoiced, so I used:

<filter name="fully invoiced" string="fully invoiced" domain="[('remaining_total','=',0)]" help="fully invoiced"/>

But that has no apparent effect when I apply the filter.

What might I be doing wrong?
