When I want to create a new customer, customer boolean field is true by default.

In my inherited view I have the field cust_type:

<field name="cust_type" attrs="{'invisible':[('customer','!=',True)],'required':[('customer','=',True)]}"/>

Although, the customer field is True the cust_type field is invisible. When I unckeck and check again the customer field the cust _type becomes visible.

What can I do to have cust_type visible from the beginning?
