Sometimes, we need to inform the web client that a specific ``ir.ui.view`` needs to use our new JS class. Note that this is a web client specific concern.

The proper way to do this is by using a special attribute ``js_class`` (which will be renamed someday into ``widget``, because this is really not a good name) on the root node of the arch:

.. code-block:: xml

<record id="helpdesk_team_view_kanban" model="ir.ui.view" >
    ...
    <field name="arch" type="xml">
        <kanban js_class="helpdesk_dashboard">
            ...
        </kanban>
    </field>
</record>

Note: You can change the way the view interprets the arch structure. However, from the server point of view, this is still a view of the same base type, subjected to the same rules. So, your views still need to have a valid arch field.
