Thanks for the reply, Marius. I just saw your reply and am not sure I fully grasp how this is safe. What if request A comes in and sets com.bryan.myproject.locationQuery and starts working on processing the rest of the request. In the meantime, request B comes in and sets com.bryan.myproject.locationQuery. Now request A finishes processing the request, upon which it has to read in com.bryan.myproject.locationQuery. Wouldn't request A now be reading in com.bryan.myproject.locationQuery set by request B?
Or have I mistaken how objects work and how requests are handled in lift? Thanks, Bryan On May 4, 2:24 am, "marius d." <marius.dan...@gmail.com> wrote: > Not at all.
