    <p><code>this.pretendRender</code> is just a reference/pointer to a function, the context of <code>this</code> when the function is called depends on many things:</p> <pre><code>a.b.c = this.pretendRender; a.b.c(); </code></pre> <p><code>this</code> will be <code>b</code> inside <code>c</code> because the function referenced by <code>c</code> is being called as a property of <code>b</code></p> <hr> <pre><code>window.a = this.pretendRender; a(); </code></pre> <p><code>this</code> will be set to the <code>global object</code> because the function referenced by <code>a</code> is being called as a property of the <code>global object</code></p> <hr> <pre><code>a.b.c = this.pretendRender.bind( this ); a.b.c(); </code></pre> <p><code>this</code> will be the original <code>this</code> inside <code>c</code> no matter what because the function referenced by <code>c</code> is a bound function that calls the original function with context set to the original <code>this</code>. <code>.bind</code> exists in modern browsers but <a href="https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Function/bind#Compatibility" rel="nofollow">must be included to be sure</a> it's available.</p> <hr> <pre><code>a.b.c = this.pretendRender; a.b.c.call( someObject ); </code></pre> <p><code>this</code> will be <code>someObject</code> inside <code>c</code> because it is explicitly given.</p> <hr> <p>Since you are using jQuery, instead of <code>this.pretendRender.bind( this );</code> you can use <code>successCallback: $.proxy( this.pretendRender, this )</code></p> <p><a href="http://jsfiddle.net/AkZZr/8/" rel="nofollow">jsfiddle</a></p>

    1. COMmmm... I get it... It's not that I want "this" to be inside the callback... I just need a way to call addColor()... And it says it's undefined if I just leave it as is

    2. COYou call `this.addColor()` and it will work when `this` is set properly. So: `successCallback: $.proxy( this.pretendRender, this )` if you are using jQuery is the only thing you need to change and it should work.. See here http://jsfiddle.net/AkZZr/8/. I did that only change and it started working.

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).
