Hi to all . I have been working on developing openerp v-7 module . I have put a button along with fields , and have also created an action to the button . But on clicking the button , it is doing nothing.

here is myform.py

from osv import fields, osv import time

class my_form(osv.osv):

_name = "my.form"
_description = 'Formview Module'
_columns = {
    'name': fields.char('Name', size=64),
    'project': fields.char('Project', size=64),
    'image': fields.binary('Image'),
    'file':fields.binary('attach file')
}

class my_form2(osv.osv):

_name="my.form2"
_description="new form"
_columns={
          'add':fields.char('Address',size=64)
          }

here is myform_view.xml
