Comment 7 for bug 1101840

tested given patch. now there is other issue with it lost all context.
Test scenario :
1 go to Sales/Customers
2 then in search area select group by country
3 click on any customer to open customer from
4 in customer form click on button Calls
expecting result should be calls for selected customer but shows all calls form all customers

im not an javascript developer but instead of :

context= _.reject(_.keys(context.eval()), function(key) {
   return key.match('group_by|group_by_no_leaf') !== null;
});

I added

 context.add({group_by:false});
 context.add({group_by_no_leaf:false});

and it helps
