    <p>I'm trying to bind a ko.observableArray of strings to a template, but I'm unable to get the template to pick up changes in the strings inside the array.</p> <p>If I bind a set of objects instead of a set of strings, I get updates to the JSON, but they don't trigger anything until I actually change the first, non-array value. I'd prefer to find an array of strings, however, as I will be able to post the data model directly back to the server without any post-processing.</p> <p>How can I get the updates to my arrays of strings to trigger, and how can I ensure that they correctly trigger changes without having to update a non-array value? </p> <p>If it's not possible to bind to an observable array of strings, how I can get the events to trigger when updating the objects inside of the observable array?</p> <p>See the example here: <a href="http://jsfiddle.net/gcEHC/2/" rel="noreferrer">http://jsfiddle.net/gcEHC/2/</a></p> <p>In this example, array3's data will be reflected in the model when value is changed, but changes to array1 and array2's data will never show up.</p> <p>JS:</p> <pre><code>var ViewModel = function() { this.value = ko.observable("hi") this.array1 = ko.observableArray(["hi", "there"]); this.array2 = ko.observableArray([ko.observable("hi"), ko.observable("there")]); this.array3 = ko.observableArray([{ data: "hi" }, { data: "there" }]); }; ko.applyBindings(new ViewModel()); </code></pre> <p>HTML:</p> <pre><code>&lt;div class='liveExample'&gt; &lt;p&gt;&lt;input data-bind='value: value' /&gt;&lt;/p&gt; &lt;div data-bind="foreach: array1"&gt; &lt;p&gt;&lt;input data-bind='value: $data' /&gt;&lt;/p&gt; &lt;/div&gt; &lt;div data-bind="foreach: array2"&gt; &lt;p&gt;&lt;input data-bind='value: $data' /&gt;&lt;/p&gt; &lt;/div&gt; &lt;div data-bind="foreach: array3"&gt; &lt;p&gt;&lt;input data-bind='value: data' /&gt;&lt;/p&gt; &lt;/div&gt; &lt;/div&gt; &lt;pre data-bind="text: ko.toJSON($data)"&gt;&lt;/pre&gt; </code></pre>

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.
