Hi,
I have 2 Stateful snippets in a page :
1. a InvoiceList snippet that

system
2. If a client RequestVar is present lists the invoices for that
client
2. a AddInvoice snippet that displays a form and adds an invoice

You want to use it yourself or contribute it to Lift?

Hi All,

Oops in the previous code it's actually :

val clientBox = ViewClient.currentClient
val client = ViewClient.currentClient.open_!
def add (inhtml: NodeSeq) : NodeSeq = {

Unfortunately this did not solve my problem :
Let me paste the complete code :

}

val client = try {

That's why I factored this as a JQueryNodeSeq, so you can pass anything to
dialog (I've used JQuery, and figured you'd need to pass something in there ;-)
JQueryNodeSeq(ns) ~> JsFunc("dialog", JsObj("autoOpen" -> JsTrue, "width" ->

Ross,
Thanks - yes, the NodeSeq is all generated from templates internally.
The end user does not have any access to change this stuff so this
particular security issue shouldn't be a problem in this case.

If the sitemap could be specified as a function JRebel could reload it.
One approach is along the lines that setSiteMap could be passed a function e.g.

IMHO you have three options:
1. Use statefull snippet
2. Use SessionVar.
3. User RequestVar.
I went for third option. Because I don't need to retain this value
between multiple requests.
In my code i use something like:
object Index {
object postidVar extends RequestVar(S.param("postid").

lazy-load should be able to wrap anything. I'll try to put in some
