Answer

In the code fragment above, we've forgotten to give the arrays a name. Please see the correct code below:
$scope.vApplicationAreas = [ 
 { "name" : "Business Intelligence" },
 { "name" : "Social" },
 { "name" : "Samenwerken en kennis delen", "children" : [
  { "name" : "Document Management" },
  { "name" : "Information publishing" }
 ]},
 { "name" : "Productivity", "children" : [
  { "name" : "Mail" },
  { "name" : "Agenda" },
  { "name" : "Search" },
  { "name" : "Samengestelde toepassingen" }
 ]},
];
