ruby on rails - Kaminari error - undefined method `<' for nil:NilClass -

I'm facing a problem with cameramic paged. This code is:

  & lt;% table% & gt; ... & lt;% @ usuarios.each do | Usuario | & Gt%; & Lt; Tbody id = "usuarios" & gt; & Lt;% = Partial render: "Admin / read / red / UURERR_RDE", local: {usuario_rede: usurario}%> & Lt; / Tbody & gt; & Lt;% end% & gt; & Lt; / Table & gt; & Lt; Div id = "paginator-usuarios" & gt; & Lt;% = Pagnet @ Ususures ,: Parameters => {: Action = & gt; "Usuarios_page"} ,: Remote = & gt; True% & gt; & Lt; / Div & gt;  

@usuoras is not empty, I have already checked. I think the problem is on the pagnet, but I do not understand why any thoughts? Thanks!
