    <p>I have two functions <code>generate</code> and <code>test</code>. When the user clicks a button <code>generate</code> is called which then calls <code>test</code> function. I receive the following error:</p> <blockquote> <p>Pass a function that returns the value of the ko.computed.</p> </blockquote> <p>The error is thrown on this line in the test function.: </p> <pre><code>var unmapped = ko.mapping.toJS(this); </code></pre> <p><code>this</code> is my viewmodel with ko.observable properties.</p> <p>Here are the two functions. If I move the content of <code>test</code> function to <code>generate</code> everything works fine but I need the logic to be in two different functions. What can I do?</p> <p>I am very stuck here. Any help will be greatly apreciated.</p> <pre><code>generate = function () { if (!omega.validatableFranchiseGeneration.validate()) { return false; } omega.franchiseInfo.IsForGeneration(true); test(); } var test = function () { getIpsAndPorts(); for (var i = 0; i &lt; omega.franchiseInfo.LanguagesInfoViewModel().length; i++) { if ($.isArray(omega.franchiseInfo.LanguagesInfoViewModel()[i].SubMenuItemsViewModel)) { omega.franchiseInfo.LanguagesInfoViewModel()[i].SubMenuItemsViewModel = omega.franchiseInfo.LanguagesInfoViewModel()[i].SubMenuItemsViewModel[0]; } } var unmapped = ko.mapping.toJS(this); var jsonData = ko.toJSON(unmapped); $.ajax({ url: "/franchise/Save", type: "POST", // data: ko.toJSON({ folderName: FolderName }), data: { franchiseInfoViewModel: jsonData }, //traditional: true, //contentType: "application/json; charset=utf-8", dataType: 'json', success: function (data, textStatus, xhr) { window.location.href = data.redirectToUrl; }, error: function (request, status, error) { jsonValue = jQuery.parseJSON(request.responseText); omega.franchiseInfo.errorMessages([]); for (var i = 0; i &lt; jsonValue.errorMessages.length; i++) { omega.franchiseInfo.errorMessages.push({ errorMessage: ko.observable(jsonValue.errorMessages[i].ErrorMessage) }); } for (var i = 0; i &lt; omega.franchiseInfo.LanguagesInfoViewModel().length; i++) { InitializeViewLanguagesInfo(omega.franchiseInfo.LanguagesInfoViewModel()[i]); } } }); } </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.
