Processing objects with meaningful keys in ui-bootstrap typeahead

Question

Angular ui-bootstrap typeahead is a great library and I like the fact that it imitates the syntax inside Angular select directive. Still it seems that this imitation is not perfect. Do I undertand correctly that I can't use this object as the source for the typeahead?

var myObject= 
{
       '41': { term: 'cell morphological classification specialist'},
       '42': { term: 'classification specialist'},
       '43': { term: 'cell electrophysiological classification specialist'},
       '44': { term: 'cell morphological reconstruction specialist'},
       '45': { term: 'cell electrophysiology recording specialist'},

}

If I used angular select directive, I'd just use the following construction to load this object as possible options:

select id as details.term for (id , details) in myObject

Does it implies that I have to avoid such objects in my application and use this form instead?

 [
   {id: '41', term: 'cell morphological classification specialist'},
   {id: '42', term: 'classification specialist'},
   {id: '43', term: 'cell electrophysiological classification specialist'},
   {id: '44', term: 'cell morphological reconstruction specialist'},
   {id: '45', term: 'cell electrophysiology recording specialist'},
 ];

It seems ui.bootstrap's typeahead only works with an array as its source.

From the documentation :

Supported expressions are:

• label for value in sourceArray
• select as label for value in sourceArray

Now one of things you can do with typeahead is call a function to return an array :

    <input type="text" ng-model="selected3" typeahead="object.term for object in transformationFunction(myObject, $viewValue) | filter:{term:$viewValue}""  class="form-control">

And the function

$scope.transformationFunction = function(object, val) {
  var newArray = [];
  for(var key in object) {
    newArray.push({id: key, term: object[key].term});
  }
  return newArray;
};

That's not the most generic function out there, but you can then think of ways to make it more generic, depending on your own data.
