Virtual properties of embedded documents with same schema as parent document

[Gabriel Fernández Valdés]

var pageSchema = new Schema({

path: String,

body: String,

children: [pageSchema],

permanent: Boolean,

editable: Boolean

})

pageSchema.virtual('title').get(function(){

var index = this.path.lastIndexOf('/');

var title = this.path.substr(index + 1);

return title;

});

If I iterate over the 'children' field of a 'page', I can't get their 'title' through the virtual property method.  It returns undefined.

There is a similar question where more than one schema was involved. The answer was to define the virtual properties before declaring the schema as embedded, but that cannot be the case here.
