Hello dear community,

i am trying to build a module in Odoo 8 following the offifial documentation of odoo.com.

https://www.odoo.com/documentation/8.0/howtos/backend.html#build-an-odoo-module

 Now I came to my recent error [1] (Field `instructor` does not exist). This error occured after the implementation of the exercise of chapter "View Inheritance". My __init__.py , __openerp__.py and the relevant partner.py and partner.xml are copy and pasted from the doc. Nevertheless I post them into this topic as [2], [3], [4] and [5]. The error dissapears if "instructor" is replaced by "name" in partner.xml or if the code is deleted . It semms for me that 'inherit' dosen't work properly because the field 'name' is  propably in the form that should be extended and using it doesn't produce the error.

Things I've tried:

- building the module from scratch by using the given code, no effect

thank you very much in advance
