    <p>I have the following ajax request that is executed at a click of a button:</p> <pre><code>&lt;a href="javascript:test()"&gt;&lt;img src="css/images/test.png"&gt;&lt;/a&gt; function test(){ console.debug("*"); $.ajax({ type: "GET", dataType: "json", url: '/path/to/url', success: function(data){ console.debug("**"); }, error: function(jqXHR, status, error){ console.debug("*** " + status + " : " + error + " : " + jqXHR.status); }, cache: false }); } </code></pre> <p>The request response takes approximately 30 seconds to return. However, the request is received and executed by the server twice as can be seen by the apache logs. The timestamp of the requests are 30 seconds apart but the request is identical (e.g ?_=1363692320782). The click response function is called once and the error callback is invoked once (exactly 60 seconds after initial request), although the apache response is a 200.</p> <p>This problem has been reproduced in a Samsung Galaxy S2, android version 2.3.5 in a phonegap application.</p> <p><strong>UPDATE - adding Apache log entries from comment below</strong></p> <pre><code>1.2.3.4 - - [19/Mar/2013:14:07:59 +0000] "GET /pcapi/records/dropbox/08342hjg9gpqm7g/?_=1363702072225 HTTP/1.1" 200 11139 "-" "Mozilla/5.0 (Linux; U; Android 2.3.5; en-gb; GT-I9100 Build/GINGERBREAD) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1" 1.2.3.4 - - [19/Mar/2013:14:08:29 +0000] "GET /pcapi/records/dropbox/08342hjg9gpqm7g/?_=1363702072225 HTTP/1.1" 200 11139 "-" "Mozilla/5.0 (Linux; U; Android 2.3.5; en-gb; GT-I9100 Build/GINGERBREAD) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1" </code></pre> <p><strong>UPDATE - adb logcat</strong></p> <pre><code>I/Web Console(16747): * at file:///android_asset/www/js/mobile.js:1769 I/Web Console(16747): *** error : : 0 at file:///android_asset/www/js/mobile.js:1779 </code></pre> <p><strong>UPDATE - TCP/IP monitor</strong></p> <p>Putting the requests through a TCP/IP monitor shows both requests being sent with a 200 response for both.</p>

    1. COWhat about browser logs, how many requests occurred?

    2. CO@Gajotres This doesn't happen in a desktop browser, when run within weire you see only a single request.

    3. COHow easy would it be for you to humour a guess of mine and increase or decrease the time it takes the server to return to significantly longer or shorter than 30 seconds? I'm curious as to whether you'd still see the 30-second timeout you're getting. I ask because 30 seconds is a fairly common default timeout value for various things...

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).
