Updated object Snippet apply() causing 'error: missing arguments for method'

[Harry-Anton Talvik]

Hi,

My CI job exercising 2.4-SNAPSHOT with Scala 2.8.1 informed me tonight
that new apply() method in Snippet object [1] caused compilation error
with message like
[...] error: missing arguments for method list in trait CRUDOps;
[INFO] follow this method with `_' if you want to treat it as a
partially applied function
[INFO] Snippet("list", list) ::
[INFO] ^
(Using here Derek's CRUDOps trait [2] -- thank you, Derek, for creating that).

More verbosely, new apply() method, and the old one below that:
+ /**
+ * Build a Loc.Snippet instance out of a name and a
DispatchSnippet (or StatefulSnippet, LiftScreen or Wizard).
+ * The "render" method will be invoked on the Dispatch snippet
+ */
+ def apply(name: String, snippet: DispatchSnippet): Snippet =
+ new Snippet(name, ns => snippet.dispatch("render")(ns)) // Issue #919
+
+ /**
+ * Build a Loc.Snippet instance for a given name and a function.
Note that the function is call-by-name
+ * so that it will be created each time it's used. This is
useful for CSS Selector Transforms
+ */
def apply(name: String, func: => NodeSeq => NodeSeq): Snippet =
new Snippet(name, func)

list()-method looks like so:
def list (xhtml : NodeSeq) : NodeSeq = { ... }

And DispatchSnippet:

What and where and how would be the right/best way to fix this error?

Is fix for: https://www.assembla.com/spaces/liftweb/tickets/919

Try:

Snippet("list", list _)

This tells the compiler that list is a function.  It's not able to infer that with the overloaded apply() method name.
 

And DispatchSnippet:
