    <p>Apparently i don't fully understand how Angular's ng-show directive interacts with the $scope. I'm trying to hide an element when an array is empty. my html is as follows:</p> <pre><code>&lt;h1&gt;Tabs&lt;/h1&gt; &lt;ul ng-hide="tabs.length == 0"&gt; &lt;li ng-repeat="t in tabs"&gt; &lt;img src="{{t.thumbnailurl}}" /&gt; &lt;/li&gt; &lt;/ul&gt; </code></pre> <p>tabs is this:</p> <pre><code>Array 0: Object $$hashKey: "01H" created: "2013-08-20 20:15:00" thumbnailurl: "https://s3.amazonaws.com/xxxxx" __proto__: Object 1: Object $$hashKey: "01J" created: "2012-07-09 23:26:49" thumbnailurl: "https://s3.amazonaws.com/xxxxx" __proto__: Object length: 2 __proto__: Array[0] </code></pre> <p>When i load my page, ng-hide throws the following exception in the console stating the anonymous function has no method 'trim'. Obviously Angular is puking somewhere in the internals. </p> <pre><code>TypeError: Object function () { // If the string looks like an identifier, then we can return it as is. // If the string contains no control characters, no quote characters, and no // backslash characters, then we can simply slap some quotes around it. // Otherwise we must also replace the offending characters with safe // sequences. if (ix.test(this)) { return this; } if (/[&amp;&lt;"\/\\\x00-\x1f]/.test(this)) { return '"' + this.replace(/[&amp;&lt;"\/\\\x00-\x1f]/g, function (a) { var c = escapes[a]; if (c) { return c; } c = a.charCodeAt(); return '\\u00' + Math.floor(c / 16).toString(16) + (c % 16).toString(16); }) + '"'; } return '"' + this + '"'; } has no method 'trim' at watchFnToHumanReadableString (http://b.gro/campaigns#/tabs/23402:706:30) at Object.$delegate.__proto__.$watch (http://b.gro/campaigns#/tabs/23402:735:28) at http://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.js:13829:9 at nodeLinkFn (http://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.js:4406:13) at compositeLinkFn (http://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.js:4015:15) at publicLinkFn (http://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.js:3920:30) at &lt;error: illegal access&gt; at Object.Scope.$broadcast (http://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.js:8307:28) at http://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.js:7463:26 at wrappedCallback (http://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.js:6846:59) &lt;ul ng-hide="tabs.length == 0" class="ng-scope"&gt; angular.js:5754 </code></pre> <p>According to the ng-hide/show docs, this directive should be pretty straight forward and accept truthy/falsy statements that are passed to it. I'm just not sure what i'm doing wrong here....</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).
