Empty popup with right number of blank positions

I'm getting the autocomplete popup, but it's empty. I'm using a template to display it, the helper looks like this:
Template.userPill.helpers({
friendCollection: function() {
return MyCollection.find().fetch();
}
})
(or without .fetch()), it doesn't return the names {{name}}. I'm using Simple Schema with this, which shouldn't affect anything here, should it?

Start by reproducing the empty autocomplete popup with the shown Template.userPill helper, both with and without .fetch(). Inspect how the popup consumes friendCollection and renders {{name}}. Done means the expected names appear in the popup when the collection contains records.
