We have developed a custom web module which inherit parts of the original web module with the following manifest:

    {
        'name': 'Web Module Modification',
        'category': 'Hidden',
        'description':"""Changes to Web module
  1. Make Report-PDF-Filepattern working in openerp.addons.web.controllers.main.Reports
  class in index function
    ===========================
    """,
        'version': '1.0',
        'depends': ['web'],
        'auto_install': True,
        'css': [],
        'web_preload': False,
    }

This works fine on our development Environment.

after deploy this on other environments an restarting the server with --update-all option it worked first. After we update the webmodule it doesent work anymore.

Is this a problem in dependency resolution or some other inheritens problem?
