Hi,everyone,I am jacky.I use openser1.1+openseradmin0.3. Now I am troubled with a problem,and here is the detail: After I install the openseradmin, I add attribute Tel to the account_preferences_type,and then I click the link:Add New Account Preference. I fill the form like this: username:admin domain:voip.net attribute:Tel values:12456 Then I click the button:Create, and it redirect to a error page,whose content is as follows: ArgumentError in Voip account preferencesController#create wrong number of arguments (1 for 2) RAILS_ROOT: /usr/local/openseradmin-0.3/script/../config/..
