get increment ID in info.phtml page on customer detail order
<p>I need to show the current order increment ID in the order details screen, on the client page, via the info.phtml file.</p>

<p>If I use <code>$this-&gt;getOrder();</code> or <code>$this-&gt;getOrderId();</code> or <code>$this-&gt;getIncrementId();</code> does not return anything.</p>

<p>If I use <code>$order-&gt;getOrder();</code> Or <code>$order-&gt;getOrderId();</code> Or <code>$order-&gt;getIncrementId();</code> Returns an error as: </p>

<blockquote>
  <p>Fatal error: Call to a member function getIncrementId () on a
  non-object</p>
</blockquote>

<p>What am I missing?</p>
