I am just getting started with the AJAX side of rails... so I am not sure if this is a bug. If I try to chain an evaluate_remote_response with another effect, I have to explicitly add an extra semicolon (;) to get it to work: :complete => [evaluate_remote_response, ";" + visual_effect(:highlight, ''element'')] However, chaining two visual_effects together does not require the extra semicolon. Also, is there a way to get evaluate_remote_response to place the errors someplace similar to the error handling available for the :update tag (:success, :failure)? Thanks, Tom
