    <p>SOLVED: </p> <p>The problem lies within Firefox 6.0.2 security. I have changed my URL request from: <a href="http://mysite.com/ajax/request" rel="nofollow">http://mysite.com/ajax/request</a> to /ajax/request and Its working.</p> <p>If you need to use cross domains, you need to use jsonp as your dataType.</p> <p>Many thanks to evildead</p> <hr> <p>My JSON request to my server returns an empty response. This only happens in Firefox 6.0.2 and Safari in a Windows Vista machine.</p> <p>The output is generated by a php script and has json/application headers.</p> <p>This returns empty response:</p> <pre><code> $('#ajaxcall').click(function(){ var ts = new Date().getTime(); var urlz = $('#targeturl').val()+'/'+ts; var dataString = $("#datazz").val(); $.ajax({ type: "POST", url: urlz, data: "data="+dataString, success: function(data){ var obj = jQuery.parseJSON(data); for (var i = 0; i &lt; obj.length; i++) { var object = obj[i]; for (property in object) { var s = property + "=" + object[property] + "&lt;br&gt;"; $("#console").after(s); } } } }); }); </code></pre> <p>As well as this:</p> <pre><code>$( "#tags" ).autocomplete({ source: function( request, response ) { $.post("http://mysite.com/v2/ajax/tag_suggestion/ab", {data:request.term}, function(data){ response($.map(data, function(item) { if ($('#tagsboxvals').hasClass(item.name.split(' ').join('_'))){ return null; } else { return { label: item.name, value: item.name } } })) }, "json"); }, .... }); </code></pre> <p>Thanks for your help</p> <p>Edit: This is what the PHP script is generating:</p> <pre><code>$arr = array( array('name'=&gt;'pizza', 'point'=&gt;'1'), array('name'=&gt;'blt', 'point'=&gt;'1')); header('Cache-Control: no-cache, must-revalidate'); header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); header('Content-type: application/json'); echo json_encode($arr); </code></pre> <p>It's a well formed JSON document.</p> <p>Headers: Response Headers Date Wed, 07 Sep 2011 23:58:42 GMT Server Apache/2.2.3 (CentOS) X-Powered-By PHP/5.1.6 Expires Mon, 26 Jul 1997 05:00:00 GMT Cache-Control no-cache, must-revalidate Pragma no-cache Content-Length 29 Connection close Content-Type application/json Request Headers Host mysite.com User-Agent Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:6.0) Gecko/20100101 Firefox/6.0 Accept application/json, text/javascript, <em>/</em>; q=0.01 Accept-Language en-us,en;q=0.5 Accept-Encoding gzip, deflate Accept-Charset ISO-8859-1,utf-8;q=0.7,*;q=0.7 Connection keep-alive Content-Type application/x-www-form-urlencoded; charset=UTF-8 X-Requested-With XMLHttpRequest Referer <a href="http://mysite.com/v2/user/register" rel="nofollow">http://mysite.com/v2/user/register</a> Content-Length 8 Cookie city=new york; __utma=100174657.1435105779.1308773648.1314994226.1315368765.113; __utmz=100174657.1315368765.113.98.utmcsr=mysite.com|utmccn=(referral)|utmcmd=referral|utmcct=</p> <p>Headers Post Response JSON Object { name="pizza", point=1} [Object { name="pizza", point=1}]</p> <p>It works fine with chrome on the same machine, but not firefox and safari.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
