It should be request.vars.records, not request.vars.id. Note, request.vars is processed by the core framework, not by SQLFORM.smartgrid, so it will be a single value if the browser sends only one "records" field in the form data and a list otherwise. The core code that populates request.vars has no way of knowing that a given field containing a single value is supposed to be a list -- that has to be handled elsewhere. SQLFORM.smartgrid itself handles this properly, but if you are going to intercept request.vars and run some custom code outside of the grid, then it is up to you to do the check and convert to a list.
Keep in mind, the "selectable" argument to the grid should be a function that takes the list of ids -- presumably you can move your code into that function, in which case, you won't have to worry about this, as the grid will handle the conversion to a list.
