    <p>If this </p> <pre><code>Object search-key=Object $family=Object </code></pre> <p>is produced by: </p> <pre><code>console.log(this.watches); </code></pre> <p>Then this is <em>obviously</em> not just one pass. </p> <p>This is not to say that it's in a loop or anything, just that this code is being called more than once.</p> <p>One might say </p> <blockquote> <p>why is search-key showing up only once then?</p> </blockquote> <p>The answer is: we don't really know because we don't see all the code.</p> <p>The most likely scenario is that <code>key</code> in the second time is the empty string</p> <p>try <code>console.log("")</code> it prints nothing</p> <p>also try this:</p> <pre><code>&gt;&gt;&gt; console.log(""); console.log(1); console.log(""); console.log(2) </code></pre> <p>copy the output and paste it in any text editor (i.e. paste it as plain text)</p> <pre><code>1 2 </code></pre> <p>it <em>looks like</em> there was nothing between 1 and 2, even though the console <em>does</em> show a cue of an empty line, but this cue disappears when you copy-paste the output as plain text.</p> <p><strong>UPDATE</strong></p> <p>well, if this process is initiated by the call to <code>WCHistory.implement(..)</code>, and this method is being called twice, then obviously, the second time, for some reason, the key is empty.</p> <p><strong>Try this</strong></p> <p>Change <code>console.log(key)</code> to <code>console.log("key: " + key)</code> and you should see something like this:</p> <pre><code>key: search-key found it Object search-key=Object $family=Object key: whhhat? Object search-key=Object $family=Object </code></pre>

    1. COIf it's two passes, then it is unexplained how "search-key" is only output once.

    2. COsame answer as cannonade ... wrong btw, the code is surely incomplete i.e. search-key would appear 2 times (or undefined or whathever)

    3. CODaniel, because the code is incomplete, we don't know how the console.log works, possibly it's not printing anything because there is no search key

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).
