end

AND MY VIEW

<%= link_to(‘previous’,
:page => @item_pages.current.previous) if @item_pages.current.previous
%>

<% puts @search_sd_ui_hash[:number]%>
<%= link_to(‘next’,
:page => @item_pages.current.next,:sd_ticket=>@search_sd_ui_hash) if
@item_pages.current.next %>

FIRST PAGE OK .BUT WHEN I CLICK NEXT ERROR

You have a nil object when you didn’t expect it!
The error occurred while evaluating nil.downcase

WHAT MAY BE THE REASON
