Move the bind to an inner function, and call that function
recursively, for example:
class Image extends DispatchSnippet {
val dispatch: DispatchIt = {
case "showAll" => showAll
}
def showAll(ns: NodeSeq): NodeSeq = {
def doBinding(ns: NodeSeq): NodeSeq =
bind("showAll", ns,
"link" -> { (ns: NodeSeq) =>
SHtml.link("/viewImage", () => selected(i.id),
<img src={ i.url } />,
doBinding(ns))
})
doBinding(ns)
}
}
