I have created new module in which I wanted to extend Functionality of Recruitment module as per new requirements. So I have mentioned following details in __openerp__.py file. But it is giving me error while installing my newly created module. __openerp__.py file content:

          {
              "name"          : "XXX Application v 0.0",
               "version"      : "0.0",
              "author"        : "XXX Pvt.Ltd.",
               'website'      : 'http://www.xxx.co.in',
               "category"   : "Other",
               "depends"    : [ "base","hr","sale", "crm","account",'decimal_precision'],
               "init_xml"      : [],
               "demo_xml"      : [],
                "update_xml"    :  "security/security.xml",'security/ir.model.access.csv',"xxx_application_view.xml"],
                "installable"   : True,
                'auto_install'  : False,
                'description'   : """ """,
                'images'        : [],
                "active"        : True,
                }

I have tried with mentioning "hr_recruitment" and "hr_applicant" in depends but also it is showing error.

Error Message is :

     File "/home/fabian/openerp-7_default/openerp/osv/orm.py", line 874, in create_instance
     'You may need to add a dependency on the parent class\' module.' % (name, parent_name))
     TypeError: The model "hr.applicant" specifies an unexisting parent class "hr.applicant"
     You may need to add a dependency on the parent class' module.
