{{@index}} not working (generates a syntax error)

[itsjavi]

Hi, I've tried to output the index of an each loop, as documented in the handlebarsjs.com webpage, but it is not working. It fires a syntax error.

I've used the starter kit code, and only modified some lines:

  <script type="text/x-handlebars" data-template-name="index">
    <ul>
    {{#each model}}
      <li>{{@index}} : {{this}}</li>
    {{/each}}
    </ul>
  </script>

Browser used: Chrome 29 (latest), OSX Mountain Lion

This produces this error:

Any clue of what's happening? Is a bug? Am I doing something wrong? Thanks

At first glance it appears that that should work. Can you create a jsfiddle demonstrating the issue?

Here it is http://jsfiddle.net/SRKD5/1/
In latest Firefox doesn't work either

Somehow this is causing an empty field for the @index lookup

  options = {hash:{},contexts:[depth0],types:["DATA"],hashContexts:hashContexts,hashTypes:hashTypes,data:data};
  data.buffer.push(escapeExpression(((stack1 = helpers._triageMustache || depth0._triageMustache),stack1 ? stack1.call(depth0, , options) : helperMissing.call(depth0, "_triageMustache", , options))));
  data.buffer.push(" ");

I'm not clear if this is related to the handlebars library directly or an interaction between handlebars and the overrides that are implemented in ember.

thanks @kpdecker I tried to figure out looking at the handlebars code, but cannot find a solution.

Issue referenced in emberjs/ember.js#3030

I've found the solution by using {{_view.contentIndex}}

What should I do for multiply each blocks?
{{#each child1 in model}}
{{#each child2 in child1.children}}
{{??parent??contentIndex}} {{_view.contentIndex}} : {{child2}}
{{/each}}
{{/each}}

I strongly suspect that this is the same issue as #699.
