has_many nested form with has_one inside

I'm having a similar issue to has_many nested form with a has_one nested form within it

Basically trying to create tasks at the same time I'm creating a client, some of those tasks may be recurring which is handled through a has_one relationship to a recurring model.

So.

Client Model

    attr_accessible :tasks_attributes
    has_many :tasks, dependent: :destroy
    accepts_nested_attributes_for :tasks, :allow_destroy => true, :reject_if => lambda { |t| t['task_type'].blank? }

Task model

     belongs_to :client
     has_one :recurring, :dependent => :destroy
     accepts_nested_attributes_for :recurring, :reject_if => lambda { |t| t['recurring_type'].blank? }
     attr_accessible :recurring_attributes

Clients_controller

def new
@client = Client.new 
@task = @client.tasks.build

Client/_form

    <table id="tasks" class="table table-striped">
      <%=f.simple_fields_for :tasks, :wrapper => false  do |task|%>
        <tr class="fields>
                <td><%=task.input :task_type, :label => "Task Type", :collection => Task::TASK_TYPES %></td>
                <td>
                  <%= task.simple_fields_for :recurring, @task.build_recurring do |recur|%>
                    <%= recur.input :recurring_type, :as => :select, :collection => Recurring::RECUR_TYPES %>
                  <%end%>
                </td>
                <td><%= task.input :due_date, :as => :datepicker, :label => "Next Due Date"%></td>
                <td><%= task.link_to_remove "Remove this task" %></td>
            <%end%>
        </tr>
        </table>
        <%= f.link_to_add "Add a task", :tasks, :data => { :target => "#tasks" } %>

I can get the form to display correctly and it now adds and removes tasks correctly. But when I submit I get a 

    undefined method `build_recurring' for nil:NilClass

I'm now on the 5th attempt at doing this in different ways and it's driving me insane.

Any ideas what I'm doing wrong?

The issue is coming because of reject_if. It is rejecting the blank fields which when error comes and because of this that field is not showing up.

Removing reject_if for blank can be changed to nil, and after that validation can be handled as regular validation as handled.
