It couldn't be any easier! Luv that web2py.
Honestly, I had gotten very close to the right answer. My code was using
response.js='location.reload();' as a temp workaround for my inability to
reload just the components. But I didn't make the connection that I should
drill down into the DOM from document to div level.
However, upon trying your line, with and without a semicolon, I keep
getting Javascript error: jQuery('#grid_course,#grid_pricelist').reload is
not a function.
