    <p>This is a follow-up to <a href="https://stackoverflow.com/questions/15747211/how-can-i-bind-a-ko-observablearray-of-strings">How can I bind a ko.observableArray of strings?</a></p> <p>How can I bind an editable observable array of observable strings to a set of input boxes? I don't want to bind to an array of objects, as my underlying JSON sent from the server is an array of strings.</p> <p>The following example doesn't work (try it at <a href="http://jsfiddle.net/LDNeA/" rel="nofollow noreferrer">http://jsfiddle.net/LDNeA/</a>). Binding an array of objects with observable strings is OK, but binding the array of observable strings directly doesn't work, and the model is not updated.</p> <p>The important thing is that the entries in the textboxes are mapped back into the model.</p> <p>JS:</p> <pre><code>var ViewModel = function() { this.value = ko.observable("hi") this.array1 = ko.observableArray([ko.observable("hi"), ko.observable("there")]); this.array2 = ko.observableArray([{ data: ko.observable("hi") }, { data: ko.observable("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: $data' /&gt;&lt;/p&gt; &lt;/div&gt; &lt;div data-bind="foreach: array2"&gt; &lt;p&gt;&lt;input data-bind='value: data' /&gt;&lt;/p&gt; &lt;/div&gt; &lt;/div&gt; &lt;pre data-bind="text: ko.toJSON($data)"&gt;&lt;/pre&gt; </code></pre>

    1. COThis is definitely an issue, but if the sending back to server JSON as a simple array is the only requirement, would you accapt an object that serialized itself as a single value so that it *looked* like just an array?

    2. CO@Tyrsius - I'd accept that answer if the answer is that "this is currently a bug in knockout.js", or "this is why this could never work". :)

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.
