    <p>I have an HTML5 web page which uses audio via JavaScript. I have a basic version which loads the correct audio file (e.g., ogg vs mp3 etc), and then correctly plays sprites from that file. This basic version has only 1 javascript file, and it works on all OS/browser combinations I've tried, including: OSX (Safari, Chrome, Firefox), iOS 5 and 6 (Safari), Windows 7 (Firefox, Chrome), and Android 4.2 (Firefox).</p> <p>I now take the code and insert it into the production version. Now, the HTML page loads many other JavaScript files (e.g., jquery, jquery ui, flot). However, all of the audio code is in a single file that is included via </p> <pre><code>&lt;script src="/foo/bar/sound.js"&gt;&lt;/script&gt;. </code></pre> <p>In both cases, the code in sound.js is invoked by the user clicking on a button. On all platform/browser combinations mentioned above, the combined code works EXCEPT on iOS (tested on iOS 5 and 6 on both iPad2 and iPad3). The error I'm getting is</p> <pre><code>INVALID_STATE_ERR: DOM Exception 11: An attempt was made to use an object that is not, or is no longer, usable. </code></pre> <p>This occurs on a line that tries to set mySound.currentTime based on the particular sprite needed:</p> <pre><code>mySound.currentTime = spriteData[currentSound].start; </code></pre> <p>mySound is my sound object, and the spriteData is correct. Oddly, the same code that fails on real iPads works just fine in the iOSSimulator, regardless of whether I simulate iOS 5 or iOS 6. </p> <p>How do I go about debugging this situation? I'm at a loss of where to look and what to try. Any suggestions would be appreciated.</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.
