Hi Pascal

There is no need to use it. You use xpath to select existing nodes to apply a transformation but if you are not inherit anything then you could build the arch of the view as you need because you define all the nodes for the view.

Maybe you wanna change a tree view of a field x2many using xpath but that is not the way to go, the treeview for that fields are found dynamically, if that is the case you could define the needed view by pushing the treeview definition of the tree inside the field like:

<field name="x2many">
    <tree>
        <field name="name"/>
        <field name="others"/>
    </tree>
</field>
