I have inherited a model "account_invoice" and also inherited a view "account.invoice_form".

I want to dispay invoice total amount in compay currency, I have converted it using extra functional field "amount_toatl_cc". But i unable to display company currency symbol. Please help me with the below code

<xpath expr="/form/sheet/notebook/page/group/field[@name='amount_total']" position="after">
                <field name="amount_toatl_cc" widget="monetary" options="{'currency_field':'company_id.currency_id'}"/>
            </xpath>

Symbol not showing with above code. 

If i write "currency_id" inplace of "company_id.currency_id" it is showing selected currency symbol, but i need company currency symbol .

Thank you.
