I think you're almost there.
Try making the "allexpenses" val a function (def) NodeSeq => NodeSeq. The
function takes the "template" of the month and returns it with bound values. So
something like:
class MonthPage {
def summary( xhtml : NodeSeq ) : NodeSeq = S.param("month") match {
case Full(m) => {
def allexpenses(expenseTemplate: NodeSeq): NodeSeq =
expensesformonth.flatmap({ month =>
bind("month", expenseTemplate,
"name" -> Text( month.item ),
"amount" -> Text( month.amount )
)
})
bind("thismonth", xhtml, "expenseitem" -> allexpenses _)
}
case _ => {
Text( "Not a valid month." )
}
}
}
No need to lookup the right template then using chooseTemplate, as the method
receives the appropriate xhtml.
