Am seeking for your assistance on a slight challenge in view inheritance

There's a tree-view inside a notebook and that would like to add more fields to.

I have already inherited the main-view as shown below but i can't seem to get the new fields on the mentioned tree-view. 


Here's what i have so far and has failed. 
Disclaimer:  Am newbie so go 'hard' on me

        
            <field name="inherit_id" ref="stock.view_picking_form"/>
             <field name="arch" type="xml">
<!--                <xpath expr="//notebook/page[2]/tree/field[@name='lot_id']" position="after">-->
<!--                    <field name="gross_weight"/>-->
<!--                    <field name="tare_weight"/>-->
<!--                    <field name="moisture_cont" />-->
<!--                </xpath>-->

                <notebook position="inside">
                    <page string="Detailed Operations" attrs="{'invisible': ['|', ('show_operations', '=', False), ('show_reserved', '=', False)]}">

                       <xpath expr="page[2]"  position="inside">
                                <field name="move_ids_without_package" position="after">
                                    <xpath expr="//tree/field[@name='lot_id']" position="after">
                                        <field name="gross_weight"/>
                                        <field name="tare_weight"/>
                                        <field name="moisture_cont" />
                                    </xpath>

                                </field>

                       </xpath>
                    </page>

                </notebook>
            </field>

After implementing @jack suggestion, i  have an error which. The view can no-longer find the already defined model fields. 

Below is the error.

Note: I have a model file which is inheriting the same model as the view and the 'missing' field is already defined there. 

Advanced apologies if am asking the obvious but apparently, i can't seem to figure this one out

Thanks

Hello,

Just to check is the "gross weight" field defiantly a field which is located in the model "lot_id"?

Could you share the Python code which extends the model?

Thanks,

Jack Dane

Another good way to check if the field exists is to go to settings->technical->models and search for the lot_id model. From here you will see all the fields in this model.

Hello,

There are quite a few things wrong here, but I will try and help you best I can. Your first attempt (commented) looks promising. We all start somewhere.

Below is an example where you would have a One2many with a student model and you would like to add the last_name field to the tree view (it only has the first_name defined so far). 

If the form view is displayed as something like:

<field name="student_id"> 
    <tree>
        <field name="first_name"/>
    </tree>
</field>

You would inheirt the view like you have done and then add the field using the xpath. The expression would be:

<xpath expr="//field[@name='student_id']/tree[1]" position="inside">
    <field name="last_name"/>
</xpath>

This has added the field last_name from the Student model into the One2many.

I hope this helps if you need anything clarifying feel free to email/comment.

BTW I believe the notepad doesn't really matter as long as you start with //field_name

Thanks,
