ui-select-choices should allow object (hashtable) instead of array of objects

[kutyel]

I have the following ui-select working:

<ui-select ng-model="vm.example" name="example">
    <ui-select-match placeholder="Select...">{{$select.selected.key}}</ui-select-match>
        <ui-select-choices repeat="x in vm.examples | filter: $select.search">
            <div ng-bind-html="x.key | highlight: $select.search"></div>
    </ui-select-choices>
</ui-select>

And the source for this select is the following array...

vm.examples = [
    {key:'a', value: 1},
    {key:'b', value: 2},
    {key:'c', value: 3}
]

However, I want my "datasource" for the select to be an object literal, as it follows...

vm.examples = {
    a: 1,
    b: 2,
    c: 3
}

I have tried several times and couldn't be able to make it work, is this even possible? If it is not possible due to the ui-select current implementation... _what is the reason??_

Closing due to lack of activity.

Refer to demo-object-as-source.html for examples of how to do this. (Or see wiki)

I am adding the initial value. It is selected properly, but disappears from the list. Any idea?
