On change

did you inherit from the original view ?

Hi Jennifer:

If you want to replace a field in a form you have to inherit the "father"
form and then use xpath on inherited form to replace the field that you
wanna change.

You can find xpath use cases on several openerp modules. You can also take a
look on technical memento where it is explained.
Wishing this helps:

Ana

Hi
Find below complete set of code :

<record model="ir.ui.view" id="view_payment_write_check_form">
            <field name="name">hmo.account.voucher.payment.write.check.form</field>
            <field name="model">account.voucher</field>
            <field name="type">form</field>
            <field name="arch" type="xml">
    <field name ="line_dr_ids" on_change="onchange_price(line_dr_ids, tax_id, partner_id)" default_get="{'journal_id':journal_id,'partner_id':partner_id,'type':type}" colspan="4" nolabel="1" height="180" position="replace">
     <field name="line_dr_ids" on_change="onchange_amt(line_dr_ids, tax_id, partner_id)" default_get="{'journal_id':journal_id,'partner_id':partner_id,'type':type}" colspan="4" nolabel="1" height="180"/>
    </field>
            </field>
        </record>

Hi

Can we use the xpath when we want to replace a function i.e using Position=Replace

Thanks Ana Juaristi Olalde, that solved my question.
