activerecord validation error after a redirect_to

Hi   I have a respond_to block as below respond_to do |format| if @service_desk_resolution.save   format.js{render :action => "sd_resolution_save.rjs"} format.html {redirect_to(:action => 'show_details', :id => params[:id],:activeTab => 1) } else    format.js { render :action => 'sd_resolution_save_errors.rjs' }   format.html {redirect_to :action => 'define_sd_resolution_ui',:id => params[:id],:sd_resolution_id=>params[:sd_resolution_id],:page=>'search_sd_ticket'} end

and

def define_sd_resolution_ui        @sd_ticket_id=params[:id]     @sd_resolution_id=params[:sd_resolution]     @sd_ticket=ServiceDeskTicket.find(params[:id])     @sd_resolution=@sd_ticket.service_desk_resolution     #The following line is used to make sure days,hours,minutes get default value zero     @sd_resol = ServiceDeskResolutionEffort.new()     @sd_resol.showdata("00:00")     if(!@sd_resolution.nil?)       if(!@sd_resolution.effort.nil?)     @sd_resol = ServiceDeskResolutionEffort.new()            @sd_resol.showdata(@sd_resolution.effort)       end     end   end

My problem is in the above else case after redirect to define_sd_resolution_ui my active record validation does not show the error message as expected.which i gave in define_sd_resolution_ui.rhtml as <%= error_messages_for 'service_desk_resolution' %> Why this happens?
