    <p>As I studied the issue I am facing in <a href="https://stackoverflow.com/questions/6406123/trying-to-create-nsdecimal-in-iphone-wax">Trying to create NSDecimal in iPhone-Wax</a> I am now aiming much lower. How can I create a fully functional NSDecimalNumber in Wax?</p> <p>I have added the following two lines at the top of AppDelegate.lua in a fresh wax project.</p> <pre><code>local x = NSDecimalNumber:initWithString("2.3") print(x) print(x:class()) </code></pre> <p>The output is </p> <pre><code>(0x631e054 =&gt; 0x631d1a0) 2.3 (0x631e924 =&gt; 0x25f618) NSCFNumber </code></pre> <p>instead of something like</p> <pre><code>(0x621e834 =&gt; 0x620c550) &lt;NSDecimalNumber: 0x620c550&gt; </code></pre> <p>Turning on full logging in wax give the following trace in the debug window:</p> <pre><code>Creating class for WaxServer(0x621bf40) Storing reference of class to userdata table WaxServer(0x621bf40 -&gt; 0x621c454) Storing reference to strong userdata table WaxServer(0x621bf40 -&gt; 0x621c454) Creating class for NSDecimalNumber(0x261120) Storing reference of class to userdata table NSDecimalNumber(0x261120 -&gt; 0x6205e44) Storing reference to strong userdata table NSDecimalNumber(0x261120 -&gt; 0x6205e44) Creating instance for NSDecimalNumberPlaceholder(0x6213450) Retaining instance for NSDecimalNumberPlaceholder(0x6213450 -&gt; 0x621d7c4) Storing reference of instance to userdata table NSDecimalNumberPlaceholder(0x6213450 -&gt; 0x621d7c4) Storing reference to strong userdata table NSDecimalNumberPlaceholder(0x6213450 -&gt; 0x621d7c4) Creating instance for NSCFNumber(0x620c550) Retaining instance for NSCFNumber(0x620c550 -&gt; 0x621e834) Storing reference of instance to userdata table NSCFNumber(0x620c550 -&gt; 0x621e834) Storing reference to strong userdata table NSCFNumber(0x620c550 -&gt; 0x621e834) (0x621e834 =&gt; 0x620c550) 2.3 Creating class for AppDelegate(0x621ec50) : : </code></pre> <p>Two things are showing in this log which I did not ask for, NSDecimalNumberPlaceholder and NSCFNumber. I believe these are the source of my grief and I have no idea where they are coming from. Any ideas on how to fix the issue?</p> <p>Ultimately I want to call the method decimalValue, but wax complains that it can't call a method on a number.</p>

    1. COwould it make a difference if it were a dishonest `NSDecimalNumber`? ;)

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.
