Material: md-chips: Can't interpolate: {{$mdChipsCtrl.getPlaceholder()}}

[yelqandili1]

Hi,

I'm trying to use md-chips on my project, but it's not working. I am using the default template from the docs :

   <md-chips ng-model="tags"></md-chips>

and on the controller side I have defined tag as an array with two elements :

var tags = ['test', 'test2'];

Here's the error I'm getting:

and here's the result I'm getting :

I have tried to add a placeholder, updated to master branch and then back to 0.9.4, nothing is working.

Any ideas ?

I'm running into the same problem and can't figure out why. Modules I am pulling in, in case it helps: 'ui.router', 'ngMessages', 'ngMaterial', 'ngMaterialDropmenu', 'flow', 'ui.date', 'config', 'xeditable', 'ui.calendar', 'ui.date', 'base64', 'config', 'ui.bootstrap', 'restangular', 'angularFileUpload'

It seems that It was my mistake, I wasn't assigning tags to the scope ! @JackForbes can you check if you are doing the same thing ?

[JackForbes]

Thanks @yelqandili1 it is odd to me that the model has to be instantiated beforehand because that isn't the case for any other input types. Working now nonetheless!

I initiated the tags but it still doesn't work for me... same error

[yelqandili1]

Did you check that you have an ng-model on your md-chips + that your ng-model is instantiated and that it is an array ?

@yelqandili1 Hi. I finally managed to make it work.
I instantiated the ng-model in my parent controller but that didn't matter as the compile and link function of the md-chip directive is run before the containing controller so my ng-model is undefined anyway.
The way I managed to fix it was by manually $compile-ing the md-chip directive inside my parent controller after the ng-model was instantiated.
Hope this answer might help another poor soul seeking a solution :P

I had the same problem but after I put
$scope.tags = [];
inside my controller and it works

Same error for me. Concretely, I have an async operation that fetch the model. The md-chips keep crashing until the model is fetched...

[yelqandili1]

Exactly you have to initialize your array so that it works properly !

This isn't an ideal error tho!

[jbrizio]

To fix this, you can use ng-init directive to instantiate with an empty value:

<md-chips ng-init="tags = []" ng-model="tags"></md-chips>

See: https://docs.angularjs.org/api/ng/directive/ngInit

Might be a little complicated when you have something like: $scope.someObject.Tags

my md-chips can work, but these red error logs in console really make me crazy.
(my ng-model get from server)
any advice?

[yelqandili1]

I think initializing you're ng-model with an empty array would work (don't
override it if what comes from the server isn't an array)
