Hi i have a Problem :
I made a Modul for Odoo (Ver. 9 ) , this Modul Imports Products over Itscope API and XMLRPC.
When i want to install this Modul , Odoo is only loading a long time.
This is the Loading Screen :
 https://picload.org/image/rarigcra/modul.png
The folder structure is:
     - ->demo:
         -->demo.xml
    -->models:
       -->__init__.py
       -->models.py
      -->models.xml
   -->security:
       -->ir.model.access.csv
   -->__init__.py
  -->__openerp__.py
This are the Files:
