Thanks Ross, I think I get that.. I'm not seeing the full picture yet,
let me show a bit more of my thinking:
So, extending my previous example, I'd like to write it like this:
<h1>Items</h1>
<lift:Item.firstAndSecond>
<h2><item:which></h2>
<ul>
<lift:Item.points>
<li><point:name />
</lift:Item.points>
</ul>
<lift:item.picture />
</lift:Item.firstAndSecond>
// Emit the block twice, once for each item (first,second).
def firstAndSecond(xhtml: NodeSeq): NodeSeq = {
List(first,second).flatMap( item => renderItem(xhtml, item) )
}
How then do I implement Item.picture, Item.points to know *which* item
is currently being rendered?
thx
