As mentioned earlier, if you want to use some URL args in your code that
should not apply to the grid, you must make this explicit by passing args
that must be preserved by the grid via its "args" argument.
See
http://web2py.com/books/default/chapter/29/07/forms-and-validators#Using-requests-args-safely.
This tells the grid to preserve the URL args you are using in any URLs it
creates, and to ignore those args internally.
