Extend Ember component without changing template

You must have done something wrong. In Ember 2.0.0 you can create a component which extends from another component(and shares its template) using following ES6 syntax in components/second-component:

import Ember from 'ember';
import ExtendFromComponent from './extend-from';

export default ExtendFromComponent.extend({
  // ...
});

It renders fine with template and properties of first component. If you still can't get it right then please add your code to question.

Thanks to the question answered here How can I share a template between two components using Ember CLI? I was able to add a layoutName to the child component pointing to the parent template and solved my problem. My code finally looks like this:

import Ember from 'ember';
import ExtendFromComponent from './extend-from';

export default ExtendFromComponent.extend({
  layoutName: 'components/extend-from'
});
