I am trying to follow the radio input example in the Lift book(s), but
I cannot get it to work.
Firstly, the example in the book uses this call to the SHtml.radio
function
SHtml.radio(colorMap.keys.toList, Empty, myColor = colorMap(_))
Using Lift 1.1-SNAPSHOT and Scala 2.7.5 This gives me the error:
missing parameter type for expanded function ((x$1) => colorMap(x$1))
"colour" -> radio(colorMap.keys.toList, Empty, myColor = colorMap(_) )
So I change my code to the below:
...
var myColor : Color = _
val colorMap = Map("Red" -> Color.red, White" -> Color.white, "Blue" -
> Color.blue)
def renew(xhtml : NodeSeq) : NodeSeq = {
bind("form", xhtml,
"colour" -> radio(colorMap.keys.toList, Empty, (a:String) =>
myColor = colorMap(a) )
)
}
...
But this yields the following error:
overloaded method value -> with alternatives [T <:
net.liftweb.util.Bindable](T with net.liftweb.util.Bindable)
net.liftweb.util.Helpers.TheBindableBindParam[T] <and> (Boolean)

(net.liftweb.http.SHtml.ChoiceHolder[String])
"colour" -> radio(colorMap.keys.toList, Empty,
(a:String) =>
myColor = colorMap(a) )
Seems like the bind function doesn't like the ChoiceHolder[String]
param (?)
What am I doing wrong?!
