feat(choices): use object as source iterating over its properties

[dimirc]

We'll be able to use an object as the source for the choices (iterating over its properties)

Demo plunker

Pending:

• Need to add a watch to update choices when source object changes

@dimirc It also does not work with 'nested' objects. The following setup:

    <ui-select ng-model="actionCtrl.model.action.delimeterType" style="width:100%">
        <ui-select-match>{{$select.selected}}</ui-select-match>
        <ui-select-choices repeat="type as (type, name) in actionCtrl.delimiterTypes | filter: $select.search">
          <div ng-bind-html="name | highlight: $select.search"></div>
        </ui-select-choices>
    </ui-select>

tries to bind all the properties of actionCtrl. http://www.screencast.com/t/jMN4BZiI ...you can see here where the parser expression is wrong: http://www.screencast.com/t/iX7HgSdAMqDE ( sorry thats a diff select but you get the idea )

@pdegenhardt @dimirc I have resolved the issues and release 0.13.2

Can you please check out issue #1255 I opened yesterday?
I have the exact same problem you described and upgraded to v0.13.2 but still not working
Maybe there is still a problem when using nested objects in a multiple select?
Thanks

Hi amcdnl
Your Change #1208 broke the track by expression
Example: n in [42, 42, 43, 43] track by $index

#1208
