Hi Rolf,
<error> when working with recursive Mustaches usually means
that your recursive call is looking up the stack at the parent
object's property with the same name. This makes it run forever,
and causes a stack fault.
The remedy is to "chop down" the context stack to a
single object when making a recursive call. We discussed this
earlier this year in another thread: https://forum.javascriptmvc.com/#Topic/32525000001587007
