jquery-ui-dialog-extra gives error when used with jQuery-ui-1.9.1
<p>I am using jQuery-ui-dialog-extra to add minimize/maximize/restore buttons to a standard jQuery UI dialog. Its was working perfect when I was using jQuery-ui-1.8.16.Now I have upgraded the jQuery-ui from jQuery-ui-1.8.16 to jQuery-ui-1.9.1 .</p>

<p>Now the problem is when I click 'minimize' button of dialog, then dialog is minimized.But when I click 'maximize' button to restore the size and position the dialog remain as it is and an error is displayed on console: <code>Uncaught Error: no such method '_generatePosition' for draggable widget instance</code>. </p>

<p>For more understanding please look into <a href="http://jsfiddle.net/S4LzA/5/" rel="nofollow">http://jsfiddle.net/S4LzA/5/</a></p>
