How to max Box[CanBind] work

[Andreas Joseph Krogh]

Hi all.

 

I have this implicit to transform a OnMouseOver class:

 

case class OnMouseOver(cmd: JsCmd) extends SHtml.ElemAttr {
   def apply(in: Elem): Elem = in % ("onmouseover" -> cmd.toJsCmd)
}
object OnMouseOver {
   implicit def onMouseOverTransform: CanBind[OnMouseOver] = new CanBind[OnMouseOver] {
      def apply(str: => OnMouseOver)(ns: NodeSeq): Seq[NodeSeq] = {
         ns.collect {case e: Elem => str(e)}
      }
   }
}

 

Which may be used like this:

 

"^" #> OnMouseOver(tooltip)

 

But when using it with a Box :

 

"^" #> Full(OnMouseOver(tooltip))

 

The compiler complains:

 

Error: could not find implicit value for parameter computer: net.liftweb.util.CanBind[net.liftweb.common.Box[no.officenet.origo.frontend.lift.lib.OrigoElemAttrs.OnMouseOver]]
                    "^" #> Full(OnMouseOver(tooltip))
                                      ^

 

I thought anything which is a CanBind also could be used in a Box...

 

Any idea how to fix this without explicitly writing a CanBind[Box[OnMouseOver]] ?

 

Thanks.

Does Option work? I know there's Option support but can't remember for sure if there's

Box support out of the… Box! badum-ch

Thanks,

Same error with Option.

 

So you're saying that if there exists for any T an implicit CanBind[T], then it should work for CanBind[Option[T]] ?

That surely isn't the case, or I'm doing something wrong...

I thought so? Could be that I'm wrong, though, I haven't checked the code to make sure.

Thanks,
