I get the following error when I goto the privilege page.

NoMethodError in Employee#edit_privilege

Showing app/views/employee/edit_privilege.html.erb where line #82
raised:

You have a nil object when you didn't expect it!
You might have expected an instance of ActiveRecord::Base.
The error occurred while evaluating nil.[]
Extracted source (around line #82):

79: <table width="100%" align="center" cellspacing="1"
cellpadding="1" class="table_design">
80: <tr>
81: <% @privilege_tags.each_with_index do
|privilege_tag,ind| %>
82: <% all_privileges =
privilege_tag.privileges.all(:conditions=>"name<>'FinanceControl'",:order=>"priority
ASC").select{|p| p.applicable?} %>
83: <% if all_privileges.count > 0 %>
84: <% if ind==0 or ind==1 or ind==4 %>
85: <td>
