[Lift] Re: lift_successRegisterGC()
Are you using any Comet or Ajax or any Lift generated form elements? If you are using any of these (anything where Lift is storing a function on the server-side and presenting the function as a GUID on the client side), then it is strongly advised that you enable GC. We're not using Comet or Lift generated form elements. We are using a jQuery plugin to do autocomplete which uses ajax. Can you tell me a bit more about GC, is it a jQuery thing? I've turned off auto ajax also: // For now, disable all Lift ajax stuff LiftRules.autoIncludeAjax = session = false So, I get this error on every page: Error: lift_successRegisterGC is not defined and this error on pages that don't use jQuery: Error: jQuery is not defined Thanks! - Alex -- You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: lift_successRegisterGC()
Heh. We're only using basic templates/snippets, and url rewriting/
dispatching. We're not using lift forms, ajax, comet, mapper etc. We
just wanted a templating engine that worked well with Scala, and Lift
seems to do that pretty nicely
I'm stubborn - I'm holding to my views that web servers should be as
stateless as possible - using state for callbacks doesn't sit well
with me, yet.

Error: jQuery is not defined
