Can't handle List in `render`?

[freewind]

I have a render which contains a List:

@scalax
  override def render(self: This) = {
    val content = Search(Search.Props(self.onSearch)) :: (self.state.keyword match {
      case Some(keyword) => SearchResult(SearchResult.Props(filteredLinks(projects, keyword)))
      case _ => Links(Links.Props(projects))
    }) :: Nil

    <div>
      {content}
    </div>
  }

It will reports error when I run fastOptJS:

If I use a Seq instead, it will be all OK:

val content = Seq(
  Search(Search.Props(self.onSearch)),
  self.state.keyword match {
    case Some(keyword) => SearchResult(SearchResult.Props(filteredLinks(projects, keyword)))
    case _ => Links(Links.Props(projects))
  })

List[T] is subtype of Seq[T], scalax macro supports traversing any Seq, so it's not the cause. In your example if you replace Seq.apply with List.apply, it would work.

Something bad is happening with typecheker, for example following code compiles:

  override def render(self: This) = {
    @scalax val render2 = {
      val content = Search(Search.Props(self.onSearch)) :: (self.state.keyword match {
        case Some(keyword) => SearchResult(SearchResult.Props(filteredLinks(projects, keyword)))
        case _ => Links(Links.Props(projects))
      }) :: Nil

      <div>
        {content}
      </div>
    }
    render2
  }

By the way you could rewrite this code in following way:

@scalax
def render(self: This) = {
  <div>
    { Search(Search.Props(self.onSearch)) }
    { 
      self.state.keyword match {
        case Some(keyword) => SearchResult(SearchResult.Props(filteredLinks(projects, keyword)))
        case _ => Links(Links.Props(projects))
      }
    }
  </div>
}

I will investigate this compiler crash

Thanks, I followed the first workaround and it's working well.

I also like the 2nd, but IDEA's scala plugin mess up the style if I press format keyshort.

There is an option to turn off formatting for XML literals.
