The type inferencer determines the type to be List[Node]. Lift's convention
is that it looks for NodeSeq (it's hard to do pattern matching on List[Node]
because of type erasure) so you have to explicitly define the return type.

[Lift] Re: Snippets; having trouble with a simple example
I've found the solution to this. It seems that for some reason I
needed to provide the return type on the posts method, as so:
def posts(html: NodeSeq): NodeSeq = {
...
Odd it should fail in such a manner without it, I would expect the
return type to be inferred by the compiler, or an error given.
Thanks.

Hi, What happens when you do a clean build? Do you still get the error? Are you getting any snippet failure errors in the console when jetty is running?
