One of the issues is that they searched a lot in order-lines (sale, invoice, purchase) and filter them on party or on product or on both. In OpenERP this was already there and they got used to it to get easy an overview what a client has both in the past and for which price.
Creating a new list in Tryton isn't hard, but we couldn't find an example on how to get the party name also in the list of orderlines. We already created a very simple orderline tree:
<tree>
<field name="sale"/>
<field name="description"/>
<field name="quantity"/>
<field name="unit"/>
<field name="unit_price"/>
<field name="amount"/>
</tree>
But we want also a field
<field name="party"/>
in the tree with the party name. The part name isn't available on the orderline, but in the parent order. Adding sale.party or something didn't work. Is this possible without adding an extra function-field? and how can this be solved?
Thanks!
