    <p>I have an HTML5 webapp wherein I use localStorage to retain some client-side user settings between uses. I thought I had it all working well, but I recently find that in the WebOS browser the localStorage items are cleared after the browser is completely closed (all cards--not just my page). It is acting like it is saved to session storage, but that is not the case. Here is a minimal example that illustrates my problem:</p> <pre><code>&lt;!DOCTYPE html&gt; &lt;html&gt; &lt;head&gt; &lt;title&gt;test&lt;/title&gt; &lt;meta charset="utf-8" /&gt; &lt;meta name="apple-mobile-web-app-capable" content="yes"&gt; &lt;script type="text/javascript" src="js/jquery.min.js"&gt;&lt;/script&gt; &lt;script&gt; $(function() { $('#btnV').click(function() { var x = ''; for(var i = 0; i &lt; localStorage.length; i++) { x += localStorage.key(i) + ':' + localStorage.getItem(localStorage.key(i)) + '&lt;br/&gt;'; } $('#lbl').empty().append(x); }); $('#btnS').click(function() { localStorage.setItem('test', 'blah'); }); }); &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;span id="lbl"&gt;&lt;/span&gt; &lt;input type="button" id="btnS" value="Save" /&gt; &lt;input type="button" id="btnV" value="View" /&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>When I first load the page and click the "View" button, nothing is shown. If I click "Save" and then "View" I will see the item as saved. Refreshing the page and clicking View immediately shows the value is retained across page-reload. However, if I completely close out the browser and then go back in to the page, "View" will show no values as it did the very first time. Am I setting localStorage items incorrectly, or is my WebOS browser configured somehow to do this? I couldn't find anything relevant in the settings.</p> <p>Thanks...</p>

    1. COWish I could help, but your code looks fine so I'm guessing it's a WebOS issue (I don't have a palm device on me)

    2. CODoes this happen in the emulator? On device? What version of the OS? I've got a couple different devices and versions of the OS in the emulator so I'll try to take a look at this a little later and see where it replicates.

    3. CO@GordonWorley @Gordon Worley : Yes, it happens on both the emulator (1.4.5 SDK) and the device (Palm Pre Plus, also 1.4.5). That is all I have to test on

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).
