I have modified the code from this question but I'm running into an issue.

{% set allCats = craft.categories.group('blogCategories').level(1).find() %}

{% set catArray = {} %}

{% for cat in allCats %}

    {% set catArray = catArray | merge({(cat.id):craft.entries.relatedTo(cat).total() }) %}

{% endfor %}

{% set catArray = catArray|sort|reverse %}

{% for catId, count in catArray %}

    {% set category = craft.categories.id(catId).first() %}

    <li>
        <a href="{{ category.url }}">{{ category.title }} <span>{{count}}</span></a>
    </li>

{% endfor %}

Ive ran a dump on the catArray array and the category id isnt being set as the key, regardless of if I try put brackets around it to protect it, I only get the value in the array.
