    <p>When I click the save link for a new blog topic, the console output is empty values for the topic object. When I click the save link for a existing blog topic, the output is the old values for the topic object.</p> <p>Why isn't the values being assigned the property when the save link is clicked?</p> <pre><code> var viewModel = function(topics){ var self = this; self.topics = ko.observableArray(topics); self.editing_topic = ko.observable(""); self.new_topic = function(){ self.edit_topic({}); } self.edit_topic = function(topic){ self.editing_topic(topic); form.dialog({width:800, height:600, modal:true}); }; self.save_topic = function(){ console.log(self.topic()); }; }; ko.applyBindings(new viewModel(jsondata)); &lt;fieldset class="blog_topic_form" title="New Blog Entry"&gt; &lt;div&gt; &lt;label for="topic_title"&gt; Title: &lt;/label&gt; &lt;input type="text" id="topic_title" data-bind="value: topic().topic_title"/&gt; &lt;/div&gt; &lt;div&gt; &lt;label for="message_contents"&gt; Message: &lt;/label&gt; &lt;textarea id="message_contents" class="message_contents" data-bind="value: topic().message_contents"/&gt; &lt;/div&gt; &lt;footer&gt; &lt;a class="save_link" data-bind="click: save_topic"&gt;&lt;/a&gt; &lt;a class="cancel_link"&gt;&lt;/a&gt; &lt;/footer&gt; &lt;/fieldset&gt; </code></pre> <p>Edit: Here is the jsfiddle: <a href="http://jsfiddle.net/jLkxG/3/" rel="nofollow">http://jsfiddle.net/jLkxG/3/</a></p> <p>When you run it, it will assign the default values. However, if you edit the textbox and click savelink, it will output the original (initial) values instead of the values entered in the textbox. </p>

    1. COCan you post a jsfiddle for this? I can't tell what the topic() in your binding refers to since it isn't a property of your viewmodel.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
