Hi Anthony, Thanks for response.
It would be difficult for me to share the exact code (my company specific data and lot of extra code etc....) However, I am providing code snippets of the main portions that I feel are causing this problem and work flow (i have changed the variable names):- Please let me know, if you still require the exact code, then I'll try to reproduce it in a small app that can be shared as such. *INDEX :* index function from controllers returns options to be populated in select html column. It uses ajax callbacks to dynamically populate the select field. {{extend 'layout.html'}} <form enctype="multipart/form-data" method="post" action={{=URL('default','results')}} > <select name='var1'> ... <select name='var2'> ... <input type="submit" value='Submit'> <input type="hidden" name="testval" value="test" /> </form> Once the options are selected the results function is called :- def results(): if (request.vars.testval and session.var1 and session.var2) or (len(request.vars) == 0): try: del session.var1 del session.var2 except Exception : pass if (request.vars.var1) and (not session.var1): session.var1 = request.vars.var1 if request.vars.var2 and not session.var2: session.var2 = request.vars.var2 Then the session data is checked and a grid is created. Results view just displays the grid data. Now from the grid data, when I select any row and uses browser back button, I get this problem.
