[Lift] Re: What am I doing wrong?
You are using a dispatch snippet, which means the name after . in
the lift tag is passed to the dispatch method of your snippet, rather
than using reflection to find a method with the same name. So, you
need to add:
case addGame = addGame
to your def dispatch

Geez. I knew I was overlooking something stupid. Thanks for your help.

[Lift] Re: What am I doing wrong?
In your bind, you don't capture the nodes inside games:show, so the
inner bind is binding the same nodes as the outer bind.
Change:
bind(games, html,
show - gameMap.values.toList.flatMap
to:
bind(games, html,
show - { (html: NodeSeq) = gameMap.values.toList.flatMap ...
Here is a working version: http://github.com/Dridus/rickr-lift-test

I'd have to see your revised template, since I don't see games:show
there, but this error indicates that you're not within a bind --
usually because you're not in a snippet when you think you are, or
when you're using a bound prefix inside some other bind. What does
your template look like?
