Scala / Lift: CSS Selector Transforms and DispatchSnippet

Question

Is it possible to use Lift's CSS Selector Transforms together with DispatchSnippet? It does not seem to work for me.

Answering my own question... yeah, it is possible! My problem was the following: Snippet methods have to be of the type NodeSeq => NodeSeq but CSS Transformations return a () => CSSSel. A CSSSel is itself NodeSeq => NodeSeq, so the CSS Transformation is () => (NodeSeq => NodeSeq).

That means, in order to use it with DispatchSnippet it must be referenced like this in the dispatcher:

def dispatch: DispatchIt = {
  case "method1" => normalSnippetMethod _
  case "method2" => cssTransform // no _ !
}

Basically, I just had an extra _ sign at the end.

Css transformations are not () => NodeSeq => NodeSeq. Can you show more of your code?
