I have been trying to get all  the taxes that are applied in an invoice plus their amount in the account.invoice tree view but unable to get it. It shows 'n' records in the field tax_line_ids in the tree view and if I add widget="one2many_list" to the field attribute, it shows the ids of the taxes applied in that invoice in a list separated format[from table account.invoice.tax] , whereas I want to show the names of the taxes along with their amount. Been stuck at this since 3 days.
