    <p>I'm trying to add a define module method to my top-level namespace, which first defines the namespace. For example,</p> <pre><code>APP.define('modules.moduleName', function () { return {name: 'Module 1' }; }); </code></pre> <p>But it seems that with my implementation of it, there is an assignment problem. Here is a simplified example of my implementation.</p> <pre><code>var APP = APP || {}; APP.namespace = function( nsString ) { var parts = nsString.split('.'), parent = this, i; if (parts[0] === 'APP') { parts = parts.slice(1); } for ( i = 0; i &lt; parts.length; i++ ) { if (typeof parent[parts[i]] === 'undefined') { parent[parts[i]] = {}; } parent = parent[parts[i]]; } return parent; }; // Simplified example of my define function APP.define = function( name, definition ) { var namespace = APP.namespace( name ); namespace = definition(); return namespace; }; // Example Module APP.define('modules.example', function () { return { name : 'Application', module : 'APP.module' }; }); </code></pre> <p>However, it seems namespace is not assigned under the APP namespace after assigning it to <code>definition()</code>. However <code>var module = APP.define('module.example', function () { /*...*/ })</code> works. This also works:</p> <pre><code>APP.define = function( name, definition ) { var namespace = APP.namespace( name ); var module = definition(); for (var prop in module) { if (module.hasOwnProperty[prop]) { namespace[prop] = module[prop]; } } return namespace; }; </code></pre> <p>There must be something about object reference or callback scope I'm missing.</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.
