URL links to Joomla articles and photos doesn't work

[lOlIl]

Article URL

In my code there's preparation for article_url named url. See below code:

 <div class="article" style="height:100px;"><h2>{title}</h2>{introtext}<br/><br/><a href="{url}" target="_blank">Link to article</a></div>

Everything works correctly. U can see POI with article correctly - title & introtext

This is server side response problem. I always receive Json with empty article_url

Decoded json (from firebug server response & selected 2 different pois)

0 - Object { article_title="Video 8/10: Manik na Ceste hrdinov SNP", article_introtext="<p style="text-align: j...cú zaspomínať :).</p>\r\n", article_url=""}
1 - Object { article_title="Prístrešok Jama", article_introtext="<p align="justify"><img...i hĺbka 2 metre).</p>\r\n", article_url=""}
