I am trying to highlight POS orderlines when a discount is applied.

To do this, I extended the default template point_of_sale.Orderline and attempted to add a background color conditionally.

This is the inherit template I used:

<?xml version="1.0" encoding="UTF-8"?>
<templates xml:space="preserve">
    <t t-name="test.OrderlineDiscountHighlight"
       t-inherit="point_of_sale.Orderline"
       t-inherit-mode="extension"
       owl="1">

        <xpath expr="//li[hasclass('orderline')]" position="attributes">
            <attribute name="t-attf-style">
                {{ line.discount and line.discount !== '0'
                    ? 'background-color:#e7f3f5;'
                    : '' }}
            </attribute>
        </xpath>

    </t>
</templates>

The problem is:

The inherit is not applied at all.

I want to understand:

• Why the POS asset bundle is not loading my XML file

• Whether the _assets_pos bundle needs another configuration

• Or if there is a specific requirement for extending OWL templates in POS 17

Any clarification would be appreciated.
