Loop over java Map with scalate's mustache implementation

Question

Can mustache loop over a java Map? My object:

Map<Integer, String> mapTest

Tried this in my mustache template:

{{#mapTest}}
  {{.}}
{{/mapTest}}

That spits out a string representation (mapTest.toString()) of the entire object but doesn't loop at all.

Update: In hunting through the source I'm getting closer but still not sure how to do it. https://github.com/scalate/scalate/blob/ec981338c067fcf37106fb5f3bdf2fa8c4e458ca/scalate-core/src/main/scala/org/fusesource/scalate/mustache/Scope.scala#L124-125

Answer 2

You could convert the Java Map to a Scala Map.

import scala.collection.JavaConverters._
val myScalaMap = myJavaMap.asScala.mapValues(_.asScala.toSet)

I wouldn't hack the template to accommodate a Java object.
