Extending link-to

问题

I'm trying to create a custom link-to helper that will conditionally add query-params depending on the presence of a property. Right now, I'm getting an error: Uncaught TypeError: Cannot read property 'options' of undefined. I've traced that to the line var options = parameters.options in the function resolvedParams.

Here's my code:

In app/components/foo-link.js:

export default Ember.LinkView.extend({
  init: function() {
    this._super();
  }
});

In the template:

{{foo-link title='Bar' hrefBinding='bar'}}

What am I doing incorrectly? Is this even the correct approach? I've already extended SelectView's like this, so I'm not sure why this is so difficult.

I'm using Ember CLI version 0.1.5.
