Derek,
Here is my complete head method:
def head = <head><script type="text/javascript" src={"/" +
LiftRules.resourceServerPath + "/jlift.js"} />
{Script(json.jsCmd)}</head>
Also, why do you use variable binding in your case pattern (j @ JsonCmd
("processForm"...). You don't refer to the
variable anywhere in the function body, so this should work just as
nicely without it (case case JsonCmd("processForm"...)
