I don't know what is going on but here is my predicament:
When I want to access nested arrays in twig I get this error

Impossible to access an attribute ("path") on a integer variable ("10977") in KprCentarZdravljaBundle:Parts:articleDefaultBlock.html.twig at line 12

Now here is my twig code:

{% if flag == 0 or flag == 1 %}
    {% set width = 230 %}
    {% set height = 154 %}
{% elseif flag == 2 %}
    {% set width = 60 %}
    {% set height = 60 %}
{% endif %}

{% for artCats in articles %}
  {% for artCat in artCats %}
    {% set img_url = globalimagepath ~ "articles/" ~ artCat.path %}
    {% set cid = artCat.cid %}
    {% set catname = artCat.name %}
    {% set aPath = path('article_details', {'id': artCat.id, 'catname': catname|pathauto,  'title': artCat.title|pathauto}) %}
     <li>
        <article>
            {% if loop.first %}
            {% if flag == 0 or flag == 1 %}
              <h3><a href="{{ path('category_details', {'id': cid, 'name': catname|pathauto}) }}">{{ catname|teaser(28) }}</a></h3>
            {% endif %}
            {% if flag != 3 %}<a href="{{ aPath }}"><img src="{{ image('http://'~ app.request.getHttpHost() ~ asset(img_url)).zoomCrop(width,height).jpeg }}" alt="{{ artCat.title }}"></a>{% endif %}
                <h1><a href="{{ aPath }}">{{ artCat.title|teaser(79) }}</a></h1>
            {% else %}
                <h2><a href="{{ path('article_details', {'id': artCat.id, 'catname': artCat.name|pathauto,  'title': artCat.title|pathauto}) }}">{{ artCat.title|teaser(37) }}</a></h2>
            {% endif %}
            </article>
      </li>
  {% endfor %}
{% endfor %}

And here is my debug of the variable articles in twig:

For some reason I can't access any of the variables in the nested array...

Impossible to access an attribute ("path") on a integer variable ("10977") in KprCentarZdravljaBundle:Parts:articleDefaultBlock.html.twig at line 12

Do you get the error only with the 8th element in the array (the one with id 10977)? Do the iterations work before reaching that element ?

Ok sry to all the people because I just figured out I'm semi retarded :(. I used the same template for different types of results on the same index page. Actually everything was ok with this part I posted in the question, the error was in another block on my index site that used the same template but passed a normal array not a nested one :(. Sry for wasting everybody's time.

It seems like this is failing: {% set img_url = globalimagepath ~ "articles/" ~ artCat.path %}

Do {{ dump(artCat) }}. It seems to be an integer instead of array/object.

I posted the dump(articles). The artCat is inside the articles array. The problem is not in the path variable, if I put artCat.id I still get the same error but insted Impossible to access an attribute ("path") i get Impossible to access an attribute ("id")
Did you try dumping that artCat inside loop ?
Yes, all of the data is there here is one artCat: array(5) { ["id"]=&gt; int(11659) ["title"]=&gt; string(36) "Brinete li o zdravlju svojih očiju?" ["path"]=&gt; string(18) "1330007101_516.jpg" ["cid"]=&gt; int(266) ["name"]=&gt; string(18) "Zdravlje općenito" }
This is even funnier, when I put artCat[0] instead artCat.path I get this error: Key "0" for array with keys "id, title, path, cid, name" does not exist in KprCentarZdravljaBundle:Parts:articleDefaultBlock.html.twig at line 13 - So funny because the system knows its an array and what are the array keys, but when i try to access one I cant :(
